That's not the case here as the tape is advanced using a stepper motor driving a pinwheel which engages the small sprocket holes in the tape. Regards, Jeff

Cactus 6502

23 May '18

Does anyone have a good picture of Alexander Pierson's (award-winning!) Cactus 6502 computer, up-and-running, without much "stuff" in the shot? If so, then please send me a link ASAP / off-list. It's important. Thanks! ________________________________ Evan Koblentz, executive director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation

Great time as a first time exhibitor, fun as always!
by Ethan O'Toole 22 May '18

22 May '18

I think this was my 5th VCF. Still putting faces to names from the list. Had a good time, things went very smoothly. The talks sounded awesome, wich I could have gotten there earlier but work/leave. I had the SGI table. The biggest comment I got especially from the young people that surprised me was their knowledge of the SGI Indy Nintendo 64 development kit. It's rare, I don't have one (yet.) But there is high awareness of it apparently! Now that I have the feel for how things flow, it will be easier next year for me. I also met a good number of people who also said they were from the Northern Virginia area, very cool. Fun time! And as a pinball and arcade guy I mostly got slayed by my friends at the Silerball Museum Sat eve. Talked with the guy that maintains the machines for about an hour Saturday night. I dig that place (was just at the location in Del Ray Beach FL a few weeks ago.) Good times. - Ethan

I will second Bills thank you! Everything went as smooth as could be expected, especially considering all the last minute issues that popped up above and beyond all the last minute issues that normally pop up at such events!! The weather, the car breakdowns, the gate key disappearing (no VCF persons fault by the way) plus the normal chaos that reigns supreme behind the scenes. All those mentioned by Bill deserve kudos plus any we forgot to mention. I have more fun at these things every year! Not to mention everything in my display worked the whole time! (Always a bonus, never expected) Thank you Evan and Jeff and Bill and adam and Laura and Curtis (manned that gate in the rain for a LONG time!) and Victor for manning the gate all day Sunday and Corey and Jeff Jonas for constantly helping out everywhere (especially helping me) and did I mention Adam? And don't forget Adam by the way ;-) Constantly making sure Evan and jeff got what they needed while simultaneously making sure all of us exhibitors were getting what we needed. One last time: THANK YOU. Tony

New artifacts
by Evan Koblentz 20 May '18

Someone in Long Island donated an HP-2645A terminal and two CLS-18 computers (see page 9 of the PDF here: https://link.springer.com/content/pdf/10.3758/BF03211027.pdf) Thank you Rich C. for picking it up. Rich also picked up some other items from the same person that weren't needed for the museum. He will post about those. ________________________________ Evan Koblentz, executive director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation

A BIIIIG Thank You to Participants and Event Staff of "East XIII"
by svcatitc＠aol.com 20 May '18

20 May '18

This is a "Thank You" eCard (of sorts) to thank all who setup and supported East XIII. Specifically: Jeff Brace: Who always (my opinion) stays in the shadows out of the limelight, does amazing work, and does not seem to get the credit he deserves. THANK YOU Jeff for all your efforts and time donated. Evan Koblentz: THANK YOU also goes out for all your efforts and time. East would not go off without a hitch without your constant attending to detail. THANK YOU, THANK YOU! NOTE: Top billing for these two was handled by alphabetical order of last name, however they are interchangeable in their importance to the organization. Corey Cohen: For all your efforts and managing the finances of this shindig! Doug Crawford: For jumping in the last minute to save the 6502 lecture. Thank You! Tony Bogan: For helping me and the rest of the setup crew in handling chairs, tables and the stage. "The Expandable Apple" was a hit! Please thank Coop for his help! Dean & Drew Notarnicola: For Dean's talk on collections, and for both helping out as docents in the museum. Thank you and others in the museum on Saturday for allowing me to blabber on about the analog side of things, to our guests. Hopefully, I did not bore anybody. Amateur docenting can be fun! Jeff Jonas and Laura: For handling the history recordists' chores. Bill Dromgoole: For his great talk on the 1219 UNIVAC. AND OF COURSE Duane Craps, who in conjunction with Bill, worked tirelessly to get this beast running! YAY! Jeff Salzman: For picking up the reins and starting the new VCF project with MOBIDIC. Your lecture was very informative. Cynde Moya: For the talk on software preservation. Very enlightening. InfoAge / Fred Carl: For hosting us for our event, and allowing us to break the quiet solace of the campus. Roddy Wildeman: (across the hall) who IS / was immense help with woodworking tools and chores. Bill Degnan, Herb Johnson, Dave Riley, The list goes on: Thank you all for all your efforts. If I have forgotten anyone that I talked to at the show, my apolgies. AND lastly to the cleanup crew (which will most likely be the usual suspects) for the thankless job of cleaning up the chairs, tables, etc., and the mess we left. THANK YOU! I wish I could be there to help again with the back end, however, family duties do not permit. I will be there in spirit! Thank you all!

VCF parking & setup

Probably I missed this... what time(s) can exhibitors come in and setup their tables? Where we should we park? (Not the grass!) I probably won’t be there until maybe 3pm today. -- Jameel Akari

Where should volunteers park?
by Neil Cherry 18 May '18

18 May '18

This may not matter but my understanding is that VCF draws a pretty good crowd. I've volunteered to work with the IXR soldering exhibit tomorrow and I was wondering where should volunteers park, or does it really matter? -- Linux Home Automation Neil Cherry ncherry(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies

by Christian Liendo 18 May '18

18 May '18

I have two non-working SGI Octanes. Once has a blown capacitor in the power supply. The other, Just doesn't run. They are free to anyone willing to take them. I just assume not even bring them in the building. I would rather just move from one car to another. One complete Commodore PET 8032 in box with dual drive and printer all in box. Original everything. Two IBM 5150s I may also have a Teletype Model 43 and an ATT 6300 Brian is bringing some TRS-80 Model IIIs What are you guys bringing?

talk at VCF-East on audio cassettes for data; stuff
by Herb Johnson 18 May '18

18 May '18

http://www.retrotechnology.com my home page starts with Web links to my VCF-East talk, and to a Web page stuff I'll be selling there as a vendor. http://www.retrotechnology.com/restore/cass_data.html There are adults alive today, who have *no idea* what an "audio cassette" is! Shocked me. Learn how the Ancients communicated in tones! Lost technology, recovered by experts, even as we speak. Voices from the past! http://www.retrotechnology.com/vcfe_may18.html Less exciting fare. I'm adding more by the day. Lights that blink, boards covered with chips, clicky keyboards. Some of you know me - ask me about something I have you don't see. Root around my domain to see more. No IMSAIs No Altairs pls, light stuff OK? Surprisingly, I don't get axed much, about old Macs.

Chris: I might be interested in one of those Octanes if no one else is. If others are more interested however then feel free to give it to them as I already have 2 SGI machines already! Bill: Might be slightly interested in the Alpha system since I am still looking for some Unix machines. As for myself, I am bringing an Admiral 1949 TV which already has a buyer. Outside of that might bring one or two Apple systems but they are not nearly as interesting. -Lou >>* I have two non-working SGI Octanes. Once has a blown capacitor in the *>>* power supply.

Anyone have IBM PS/2 mice?
by Jameel Akari 17 May '18

17 May '18

Reminded by Tony's post... does anyone a have IBM-branded PS/2 mouse or two I can borrow for VCF? (No, didn't find any in the warehouse.) Specifically this style: https://en.wikipedia.org/wiki/IBM_Personal_System/2#/media/File:IBM_PS2_hii… Or even a little later: http://product-images.highwire.com/2952082/793c7b2c-d100-4659-8a59-ed6105d7… I've got plenty of PS/2 interface mice of course, but somehow I never kept any of the original style. Thanks! -- Jameel Akari

VCF item request
by Tony Bogan 16 May '18

16 May '18

Was wondering if anyone has an Apple II SCSI card I could borrow for the show. The only spare I have is acting up, the other is being used. I don't care if it's an earlier revision or high speed as it's going in an Apple iie not a iigs. I could try to get another profile working but since I have the scsi drive ready to go this would be oh so much better :-) Let me know if any of you out there have a scsi card you're willing to lend for a couple days. Many thanks in advance! Tony Sent from my iPhone

ANNOUNCE: VCF East XIII 8085 Single Board Computer
by systems_glitch 13 May '18

13 May '18

Some of you may have noticed that I've been extra busy/slow to reply lately. It's not just because of taxes :) This is on my bench: http://i.imgur.com/TppyO2Mh.jpg We got together on the idea of a special edition vintage computer project for VCF East last year, but there wasn't enough time between when someone mentioned the idea and the event to actually get it done. This year, I've revised my 8085 SBC design into a larger, more full-featured board as seen above. Specs as follows: * 8085 CPU * 64K Static RAM * 32K ROM available in 4K pages * Autoboot/ROM switchout circuit * 8251A USART for console port * DS1233 EconoReset * Baud rates from 300 - 38400, baud clock independent of CPU clock * GlitchBus expansion header * Single 5V power supply The board is 8x5 inches, the GlitchBus expansion stacking area provides for a 4x5 inch board. Currently I've got the prototype version running GWMON, my ROM monitor, from Ferroelectric RAM in the ROM socket. The goal is to have a customized monitor and fully functional BASIC by VCF East. This is also the first board to commit to a GlitchBus pinout/layout -- several of us have been working together offline and through IRC to get it nailed down. Eventually, you'll be able to add a storage controller (CF, floppy, etc.) via GlitchBus and boot/run CP/M! The ROM can be switched out under software control, so the full 64K of RAM will be available to user programs. The board also supports FeRAM, so it's possible to have a core-like setup for main memory. If you use FeRAM or an EEPROM in the ROM socket, the board can update its own firmware. This revision is going to be released at VCF East XIII and is a special edition that will probably be limited to the show. We'll be doing an event-long workshop to build and test the SBC at InfoAge during VCF East, just like we did with the XT-IDE and Apple II prototyping workshop last year. If you choose to assemble your board at VCF East, you'll leave with a 100% tested and working 8085 SBC. I may bring a very few CRT terminals to make available to builders of the 8085 SBC. Evan got me a high-res PNG version of the VCFed logo, which I was able to work into a copper-and-silkscreen graphic for the PC board: http://i.imgur.com/H6iJnXIh.jpg I haven't nailed down a price for parts kits yet -- that will be forthcoming. Thanks, Jonathan

FS: Motorola MEK6800D2 6800 Trainer/Dev Kit TESTED/WORKING
by systems_glitch 12 May '18

12 May '18

link: https://www.ebay.com/itm/273207889695 This one looks like it was essentially built and never used. Nothing has been added to the prototype area, it looks like the EXORcisor bus connection was never plugged in to a socket, and there was no additional RAM in U18/U19 sockets. I cleaned it up, removed some areas of excessive rosin flux, and brought the board up on a 5V bench supply. It draws around 1A with address/data info on the displays. Ran through the sample program in the manual, which worked fine. I added two Fairchild branded 6810 SRAMs to bring it up to a total of 512 whole bytes of memory :) Didn't test the cassette interface, I no longer have a cassette recorder kicking around. If you're interested and will be at VCF East, let me know -- I'll take substantially less if I don't have to pay eBay/PayPal fees and ship. Thanks, Jonathan

Reanimating Zorba (long)
by Mike Loewen 11 May '18

11 May '18

It's alive! http://q7.neurotica.com/Zorba1.jpg http://q7.neurotica.com/Zorba2.jpg After several extended troubleshooting sessions, my Telcon Zorba (Nomis 9) is up and running! I don't know what happened to this system, but it had some major problems. When I received the system, it did nothing: no lights, no fan, no display. My first thought was a bad power supply, and a voltage check showed that the +12VDC line was down to around 8V. No filament on the CRT, either. Unplugging the display board allowed the 12V line to pop right back up to spec. So, something was wrong on the display board. A visual check of the display board didn't reveal anything obvious. I used my DMM and a curve tracer (connects to my oscilloscope's X-Y inputs) to look for anything odd. I found a large diode which appeared to be shorted. On desoldering it, it just fell apart! No idea what caused it to short, but I ordered some horizontal output transistors just in case. The diode was a MR854 400V 3A fast recovery diode, and the HOT was a BU807. The old HOT tested similarly to the new transistors, but I replaced it anyway. I replaced the diode with an MR856 (600V 3A) for an extra margin of safety. After adjusting the power supply, I plugged everything back together, and bingo, the filament lit up and the 12V line looked good. Still no display though, so I started looking at signals. With the help of the schematics, I traced things back to the CRT Controller chip (CRTC), an Intel 8275 programmable CRTC. No signals coming out of the CRTC at all. I found an Intel P8275 on Ebay, and sat back to wait. (tip of the hat to Ian Primus for troubleshooting advice) After I replaced the the CRTC, the system immediately beeped (which it had never done before), and eventually the boot display came up, telling me to press <ENTER> to boot. A slight tweak on the horizontal hold pot was all it took to stabilize the display. So, second problem solved. However, pressing <ENTER> did absolutely nothing. There was voltage going to the keyboard (the caps lock LED would toggle), but nothing was happening. I checked the output from the keyboard on the scope (looked okay) and from the inverter going to the 8251A USART for the keyboard. Time to haul out the logic analyzer and find out what's happening on the bus. On the diskettes which came with the Zorba, there was one labeled "Gemini Zorba Source BIOS 1.7A". I imaged the disks with IMD, and was able to pull the files from them. On the BIOS disk was source code for the CP/M BIOS, as well as source for the boot ROM. I dumped the boot ROM with my Data I/O 29B and ran it through a disassembler (z80dasm). Things didn't quite match up, and it was obvious that the ROM in my Zorba wasn't exactly the same as on the disk. Working with z80dasm on the Linux side and Z80ASM on the CP/M side, I was able to create an ASM file which assembled and loaded to an exact copy of my Zorba's boot ROM. Armed with the correct assembly listing, I hooked up the logic analyzer HP (1650B) to see what was happening. The code was stuck in a loop, waiting for the floppy drives to home to track 0. The heads would move (if initially off of track 0), but the code was waiting for an interrupt from the FDC (1793) which never happened. I started checking the circuitry for the interrupt chain, and found a shorted 2N3904. After I replaced it, the code moved on, but again was looping, this time waiting for the keyboard. I intially thought the USART for the keyboard was bad, but swapping it with another 8251A on the board didn't change anything. A check of the signals going to the USART showed the proper select lines activating, but the RxRDY line never showed a character ready. I finally checked the clock line for the USART. The frequency should have been 19,230Hz, but was nowhere close. The clock comes from an 8254-2 Programmable Interval Timer, which has 3 independent counters. The 8254 is programmed early in the boot process, and counter 3 takes the 8MHz clock and divides it by 416 to provide the TX/RX clock for the keyboard USART. The USART then divides the 19,230 clock by 16 to provide something close to the 1200 baud clock for the keyboard. The logic analyer showed the correct programming sequence going to the 8254, but only random values were coming out. So, back to the order form for a couple of 8254-2 chips and some other spares for inventory. As soon as I replaced the 8254 (actually with an 82C54-2) the frequency counter showed 19,230 from counter 3, and the keyboard magically came to life. It booted! This is the most difficult micro fix I've ever had to make. The tally of bad components reads: MR854 diode (shorted) 8275 CRT controller (dead) 2N3904 transistor (shorted) 8254-2 programmable timer (dead) I ended up using the following test equipment to find the problems: Tektronix 485 oscilloscope HP 1650 logic analyzer Curve tracer module Logic probe DMM Data I/O 29B programmer Advantest TR5823H Frequency counter I also wasted some time chasing imaginary floppy drive problems. To simplify things, I was only using a single floppy drive. After chasing code with the logic analzyer and the source listing, I discovered that whoever wrote the boot ROM code decided to wait for BOTH floppy drives to interrupt when they reached track 0 before moving on. If one of the drives is bad, or not installed, the code will loop forever waiting on the bad/nonexistent drive. All told, it was an interesting journey, and I now know more than I ever wanted to know about the Zorba. :-) Mike Loewen mloewen(a)cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

VCF East XIII - Building 9059 Room Planning
by Jeffrey Brace 09 May '18

09 May '18

FYI 9059 will be our classroom instead of the model train room down the hall from the museum. So I took pictures of the room: <https://drive.google.com/open?id=1HNi6Lnajl6TxhKhlkW8YT5UltKYSwamh> Looks like they put new tiles on the floor, painted them and the walls. Also there are new electrical outlets on the wall as well as ethernet ports. The projector screen is there *and* works. I made sure to test that it unrolls. The projector on the ceiling *doesn't* work, so we need to supply one. I counted 22 adult chairs and 10 childrens chairs, so I won't count them. I had thought about mentioning this room a few times in our VCF East planning, but we never go through our list so I kept forgetting about it.

08 May '18

They were expected to arrive May 16, but I got a message from UPS that they will be delivered tomorrow 5/8. A whole 8 days ahead of schedule. So I need to give t-shirts to: 1) Exhibitors 2) Volunteers 3) Instructors Who else are we giving t-shirts to? I want to separate them out. I should have all of their sizes. Now I'm wondering about folding them. Who can do this? Laura? It needs to be done by Thursday night, so that they are ready to go Friday. -- ========================================= Jeff Brace Vice President Vintage Computer Federation

Museum Report 2018-05-06 May 6, 2018
by Jeffrey Brace 07 May '18

07 May '18

Got here earlier than usual because of the weekend event says the museum should be open at 12. Tony was here moving the new backdrop for the featured artifact. I helped him move it. He also measured his exhibit table and looked at the Apple //. We had about a dozen visitors today from the casual run through, to the give me a tour to the move extensive long tour. Connor S stopped by with his mother and grand parents visiting from St. Louis. I let him try some BASIC programming on the original chiclet PET as well as play Little Computer People on the Commodore 64. I asked him for an update on his science fair that he did on vintage computers. It sounded like it went well. I assessed the state of various machines to see how we could get more demos running on them. One thing that I would like to have is a MOD player for the Amiga 1000 called EdPlayer. Could someone bring that in? I would love to get other micros working in the museum such as: Getting the floppy drive working on the TRS-80 and run some demo on that machine. Getting an iPod to load programs into the Apple /. Getting the tape drive working on the Commodore PET etc. -- ========================================= Jeff Brace Vice President Vintage Computer Federation

Dozens of casual visitors going through the museum It was a big event all over Monmouth County. It was Weekend in Old Monmouth advertised via Monmouth County Historic Commission. One unique visitor worked on the project for the Original IBM PC. She said that the group making it took the little name plate and put it on badges. But one guy objected because the name plate was supposed to be for production computers. She recognized the manuals and asked where was DisplayWriter. It's fun when you get visitors that have worked on the original machines. -- ========================================= Jeff Brace Vice President Vintage Computer Federation

Museum report
by Evan Koblentz 05 May '18

05 May '18

Don C. and I met at the museum at 10am today. We worked on various projects for VCF East and the museum itself. Most notably, we constructed a wall/backdrop for the featured artifact exhibit. It is L-shaped: 6.5 feet tall and 4 feet on each side. We painted it the usual gray. Next time I'm there, I'll trim the sides/top (probably with dark green) to make it stand out. ________________________________ Evan Koblentz, executive director Vintage Computer Federation a 501(c)(3) educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation

talk at VCF-East on audio cassettes for data
by Herb Johnson 04 May '18

04 May '18

I've agreed to give a casual talk at VCF-East, on the use of audio cassettes and recorders for program storage on first-generation (1970's) vintage computers. I'll describe how a "TTL logic gate" can create audio waveforms and interpret them, with little more than software and hardware. I'll try to point to early Altair/IMSAI class S-100 computers, early COSMAC (RCA 1802) computers, possibly others. I'll try to reference the earliest efforts to create various standards. And I'll point to current recovery work on some old cassettes. I'll likely point to various Web pages for details and images - no PowerPoint presentations, no exciting videos. Maybe one wailing audio tape. Some stuff I won't know - I have an idea about that. So why do this? There's recent and successful efforts, to recover programs today from COSMAC tapes 40 years old now - that's interesting. Many period micros are operated today, with MPEG music players acting as the audio source; so it's still in use that way. I mentioned the techie bits of cassette storage and retrieval - I'll draw some schematics. And unfortunately, experience with audio cassettes is becoming "lost" - a generation of young adults have NEVER handled such a thing. (shrug) so it's a teaching moment for those folks. Unaccustomed as I am with public speaking (snort!), I'll welcome some discussion from the audience. I'm sure some attendees to VCF-East will know more than I, about some part of vintage-time use (or modern use) of audio cassettes for data. So people with an interest or experience, may want to think in advance about what they might say, bring props, whatever; but keep to the point and be brief. I'm simply making a point, that cassettes-as-storage was a REAL THING that mattered with first-gen microcomputers; it wasn't that hard; and these things are surviving pretty well. One thing I'd like to hear from others about, was the volume of cassettes available for 1980's video-gaming "systems", for instance the Timex/Sinclair 1000. Early Apple IIs and TRS-80's used cassettes. Those systems weren't on my radar at that time. My impression is that a lot of little companies, computer clubs, individuals, distributed bunches of those program cassettes in the period. If anyone remembers cassettes for their system, consider speaking up at the talk. If you are so moved about some notions on the subject, email me via my retrotechnology.com site. A Web search of my domain will find plenty of cassette material, but it might spoil any surprises from my talk! ;) Herb -- Herbert R.
