Last minute Festivus Info
by Jeffrey Brace 03 Dec '16

03 Dec '16

There is a train show going on, which is a pay to enter event, so please be aware to close the gate behind you. It is better to park in the main parking lot, unless you are unloading stuff. There is a hot water dispenser connected to the coffee machine for those tea drinkers out there. Does anyone have any glow in the dark tape or lights? I just noticed how hard it is to see the door entrance area in the dark. -- Jeff Brace - ark72axow(a)gmail.com

Van is packed and ready for the rest of us.
by Ian Primus 03 Dec '16

03 Dec '16

Finally finished herding everything together. I think. I have a van packed full of televisions, game consoles, and alcohol. I have like 95% of a Festivus back there. If there's something I forgot, well, try to drink to forget the fact that I forgot it. I'm aiming to be there by 10 tomorrow. See you all soon! -Ian

MIDI Sequencing programs for Windows 3.0/3.1
by Matt Patoray 02 Dec '16

02 Dec '16

Hello, I am looking for a Midi Sequencing program that will run under Windows 3.0 or 3.1, looking to use my Roland LAPC-I a bit more, and it's patches do not map to general MIDI so I would need something to rearrange the tracks. I seem to remember a program called Cakewalk that I had a demo of years ago. I was wondering if someone might have something for download or sale. Thanks in advance, -- Matt Patoray Owner, MSP Productions KD8AMG

Coffee is too caffeinated for me. Otherwise I'll use the microwave but it's noizy. Thanks for linked photos of the cafeteria. Makes it clear now, there's a sink, a small microwave, a conventional commercial coffeepot for ground coffee, many refrigerators. Possibly a sliced bread toaster on that shelf at the end of the refrigerators; a hot water pot on the right shelves. For those who stay overnight, it is a blessing and a convenience to make a simple breakfast on-site. I'm very thankful to InfoAge (and the state of NJ) for this facility. Herb -- Herbert R.

Speaking of looking for stuff at Festivus
by Ian Primus 02 Dec '16

02 Dec '16

Looking for some blank/used/junk tapes - specifically 4mm DDS1 tapes. There was a whole box of 'em on the free pile at VCFMW but I didn't think I needed them at the time. Now I do. Doh. Also, speaking of tape, garage sale season is over, so my supply of blank audio cassettes has dried up. Anyone got any blank/used/junk cassettes they are looking to get rid of? -Ian

Yeah, I had noticed them putting the tape reels on backward. They also had a Decwriter II in the scene set in 1969. Not only was that a bit early for a Decwriter II, but the big systems at MSC were IBM. I was also terribly amused at the idea that they needed a strip of paper tape to log in to the system. BLS

Festivus Wanted: DDR3

Anyone have any free used DDR 3 that they would part with? My "modern" PC is aging a whopping five years old ;) I have an Dell Alienware Aurora R2 which takes 2-channel DDR3. The Capacities are 1GB, 2GB, 4GB. I have two 2GB sticks in there now with two slots free. Speccy says that they are at 668Mhz even though the specs say 1066 MHz or I333 Mhz can work in my machine. Looking to add at least 2 - 2GB sticks. If not free, then maybe a low cost? Or a place that sells them cheap? -- Jeff Brace - ark72axow(a)gmail.com

FS: TRS-80 Model 1 with Monitor, Expansion Unit, Disk Drive
by Systems Glitch 01 Dec '16

01 Dec '16

All, I've got a TRS-80 Model 1 from the Philly purchase. I had time today to set it up and power it on. It comes up into BASIC, responds properly to BASIC commands/keyboard works. No further testing done at the moment, I don't know much about TRS-80s aside from the Model 100. I've got the matching expansion unit, B&W monitor, and a 5.25" disk drive which claims to have a Shugart SA-400 inside. The expansion interface appears to have the RS-232 card installed. Power supply is of course built into the expansion interface, I don't have a separate one. The keyboard is missing the ?/ key, immediately to the left of the right shift key. Looks like the expansion interface is the expensive bit to this. Open to offers, I have nothing to go on for pricing except closed eBay listings. Prefer to bring to Festivus, of course. I'll see if any of the odds n ends go with it, I may have disks. Thanks, Jonathan

PDP 8i's (10 yes 10 of them)
by william degnan 01 Dec '16

01 Dec '16

Guys, Tomorrow I plan to go to the family's house who owns 10 PDP 8i's. I don't want one just so you know, but I am hoping to find a good home for them. I mentioned the VCFed museum, etc. when I visited them last time to see if they'd donate one, but they want $$ for these. I am thinking they may have an inflated idea of their value. Here is a picture set: http://www.vintagecomputer.net/pictures/2016/PDP8i/ The tape units are not DEC, they look like IBMs. They're is not returning my emails so I am going to pay them a visit to see what's what with these machines, on my way to festivus. He lives in the NJ pine barons near my old High school home town, Medford NJ. Anyhoo...if I don't show up at the festivus now you know why. What I need from you all BEFORE Saturday morning 1) Show of hands for anyone interested in a complete PDP 8i system (each is three full sized rack cabinets) 2) What would you pay for such a thing, assuming you had to rent a truck, move the racks into your truck, etc. Look at the condition closely, these ain't new. I want to take these informal offers info to these people to see if I can get him to budge. I am looking for honest offers given the circumstances. Although I don't mind discussing this publicly feel free to send to me serious offers privately via vintagecomputer.net/contact.cfm. I will print the forms and deliver to the owner. If there are less than 10 offers I will discuss some sort "how do we part a few of these out" deals. Bill

27 Nov '16

Dean, Drew, and I worked in the warehouse from 10am-6pm on Friday. An untrained eye would still see it as messy, but we got a lot done. Highlight: we moved the contents of several pallets onto shelving carts, which makes things easier to access/catalog and makes floor space. Lots more to do, but this was the first warehouse day since February so we are happy just to make progress. We have a plan for where to continue next time.

Floppy Days #67 - HP Series 80 Part III
by Randall Kindig 27 Nov '16

27 Nov '16

The HP Series 80 (HP83/85/86/87) This episode is the third and final in a series about the Hewlett Packard HP-85 computer, or more accurately, the entire line of similar computers known as the HP Series 80. Once again, I have the tremendously knowledgeable duo of Everett Kaser and Vassilis Prevelakis helping me impart information to you about that venerable line of historically significant desktop computers. In this episode, we will primarily be covering tech specs, peripherals, expansion, magazines and newletters, books, emulation, modern upgrades, connectivity to modern computers, buying one today, community and Web sites. Wow, now that I list this out, it’s obvious we have a lot to cover. In addition, I will briefly talk about my new vintage computer acquisitions, feedback and perhaps a little news. http://floppydays.libsyn.com/floppy-days-67-the-hp85b-computer-part-3-with-… <http://floppydays.libsyn.com/floppy-days-67-the-hp85b-computer-part-3-with-…> Randall Kindig host Floppy Days floppydays.com

FS: At Festivus
by Systems Glitch 27 Nov '16

27 Nov '16

All, I've got a few items I'd like to sell at Festivus. Contact me off-list with interest or for pictures. As follows: 1x IBM 5150 PC: This is the "absolutely first" PC from the Philly pick-up. Turns out it's a common 256K late production PC with the 60-some Watt power supply. Little bit of marker on the front. Has dual FH 5.25" floppies, IBM floppy adapter, 3rd party RAM expansion, and 3rd party MDA/parallel card. $100 OBO. Add XT-IDE rev 3 card with 64 MB DOM for $100. I'll write out a boot disk, and the XT-IDE utils if you like. No monitor/keyboard included. 1x Lawrence Livermore Labs MST-80B trainer *board only*. This is one that came to me without the suitcase. It was apparently a parts donor board, I repopulated it and got it working. Your choice of the "stock" LLL ROMs or the modified code that came with this lot of trainers. Not sure what the different ROMs do, I've dumped them so you can take a look if you'd like. Keypad operation appears identical to stock ROMs in my testing. $100 OBO. I can bring my bench supply for testing. 2x BAFCO Inc. Frequency Response Analzyers. I bought these at auction for the panaplex displays. One uses an IEC cable and I've powered it up, does stuff and appears to analyze the frequency response of a 50R coax jumper :) The other uses a 3-pin adding machine style cable, I haven't powered it up. One has asset management stickers from Comsat Labs. $50 each OBO, asking price is what I think the panaplex displays are worth. 1x HP 1415A Time Domain Reflectometer. Picked up at auction with other test gear. Does "stuff," makes a trace on screen that sort of matches what I'd expect for a time domain reflectometer. No further testing. It does include converters to go from those early high-frequency RF connections (not sure what they're called, I'm used to seeing them on ancient Gen-Rad stuff) to BNC. Make offer. 1x Gen-Rad 1217-B Pulse Generator. Mix of tubes and transistors IIRC, but still makes pulses like this: http://imgur.com/X1KwZ8e I haven't used it in a while, hence the selling. Wouldn't call it fully tested/calibrated, but it does work. $50 OBO. Might have more depending on what I have time to test this week. PM me if I'm supposed to be bringing something for you, just to make sure I've got it on my list! Thanks, Jonathan

As much as I truly do love to make and share my ribs with you, I must pick up some equipment that Saturday morning; thus, I will NOT have the time to spend making my ribs for those of you at Festivus. There is just so much happening at this time of year and there's too little time for it all to happen in. Perhaps, to make it up to you, I will whip up a couple of racks when VCF rolls around.

Looking for XXDP TAP image
by william degnan 27 Nov '16

27 Nov '16

If anyone knows of or would be willing to make me an XXDP TAP image compatible with a 16K PDP 11/40 that I can convert into a CONSOLE script? I'd take a RAM dump after loading XXDP on say a 11/35 11/40, probably also 11/34, 11/05, 11/10. If I could run TU58 emulator I would...it's not working correctly, I have tried everything I can think of. I will keep working on this and I also still can't boot my RL11 (RT11 on RL02). Given my circumstances the next thing I imagine to attempt is the download of XXDP "manually" via a CONSOLE as if it were dumped from TU58 tape just before initialization. I do have BASIC running in core at the moment, at least there's that. Given at least that works my theory about my inability to boot RL11 or TU58 could be that that I have a DMA-related UNIBUS issue. I have not supplied every detail of my system analysis here in this message but that's what I think is the "core" of the issue. har har. Open to suggestions thanks. Bill

(Mostly) 68k Macs at Festivus (FTAGH)
by David Riley 26 Nov '16

26 Nov '16

(Sorry if this is a duplicate; I wanted to make sure the MX change didn't break things) Hi all, As promised, I've catalogued my uncle's old machines that I'm bringing to Festivus. I've removed the ones that are already claimed, everything else is available. All have had batteries removed (some were stored in a garage with them in, as noted, with the usual disastrous effects). Except where noted, most of this is untested, so expect to have to perform some maintenance. Please let me know ahead of time what you'd like so I can pre-assign recipients. I'd like to see it all go at Festivus. 2x LC 475 1x Performa 400 (LCII) 2x LCIII 1x LCII 1x LCII with bad battery corrosion on LB, may be unrecoverable, but RAM, Ethernet card and case/parts seem fine 3x PowerBook AC adaptors 1x PowerBook Duo AC adaptor 1x PowerBook G4 AC adaptor 2x AAUI-10Base2 adaptors 1x PowerBook video adaptor 1x "puck" PowerBook AC adaptor, computer end broken (tip snapped off) In addition, I think there might be a PM7200 in there, and I have a PM7100/80 (very dirty, unknown condition) coming my way that I should be able to bring. Please mail me directly with enquiries. - Dave

Commodore stuff at Festivus
by Herb Johnson 18 Nov '16

18 Nov '16

http://www.retrotechnology.com/herbs_stuff/amiga.html These are Amiga, C-64, C-128, VIC-20 related service manuals, published by Commodore. I'll bring them to Festivus for some deal. Probably 25 pounds of manuals in a box. Most of these are probably online as PDF's, I'm told. I'd like something for these - ALL of these. Same deal, for a dozen books about C-128's or C-64's or related devices. Assembly language, programming, user's stuff. Another box. I'll also bring a VIC-20 and C2N cassette drive, both in the box. I have a loose C2N too. Again, looking to pass on there for a modest price. These are common., they are not "mint". Herb -- Herbert R. Johnson, New Jersey USA http://www.retrotechnology.com OR .net

EAI TR20 analog computer exhibit

Bill and all: I've taken the liberty to post a reply under a proper subject line that's relevant to the thread. Not "digest question blah blah" which is irrelevant and will be impractical to search back for in the future. I really encourage people who post, to use relevant subject lines, but this is up to the Moderator to enforce, (except when he doesn't). Bill, I worked with EIA analog computers long ago, and I'm an old electrical engineer. So it's good to see this EIA TR20 will be restored and demonstrated. But very few people in the VCFed list, have any experience with analog computing or with differential equations. Fewer visitors will know this stuff. The classic demo of these sorts of systems, is some kind of "bouncing ball" display. Everyone has seen a ball bounce, so it's familiar. There ought to be enough integrators to make a damped oscillator. Since you want a chart recorder output, the frequencies will be sub-audio. But you might allow for a speed-up at audio rates, so an oscilloscope and speaker can demonstrate operation, without requiring the chart recorder and using up paper and ink - all points of failure, weeks and months later. If it were my choice, I'd go "audio" so it's easier for the docents to demonstrate the unit and avoid problems with chart recorders. That's my considerations. Something simple, familiar, and convenient to demonstrate when you aren't there. The amazing thing will be that it works, and has been preserved. We can run real programs, another day.

>> I need analog math problems to be submitted, so that when the TR20 is restored, we'll have simulations to run on the computer. I'll make a list of what computational modules we have so you know what to work with, i.e. integrators, DFG's, summers, etc. The plan is to have an XY recorder and XY scope for results output. We have some books on the subject. Aren't there also samples in the TR20 documentation? >> As you saw, Evan becomes the safety net and guides us all in the right direction. As he self proclaims himself: "chief cat-herder". It all started when nobody else was foolish enough. :)

>> Evan,If you would like a video camera for the display, I've got a broken JVC Everio GZ-MC500. It was a cool DVD-quality Handycam-esque unit from 2005. It might be too modern in one sense, but it's small. And being broken, having it glued to a wall seems like a good use for it. That's perfect, thank you. Can you bring it to Festivus? If not, then I'll let you know where to mail it.

Hi Eugene; I am a Newbe also, and for what it is worth, I figured I would intro myself to you and the group. I am the one working on the EAI TR20 analog computer exhibit, since I worked at EAI from 1978-1985. I now become(?) the resident expert(?). We all know the definition of an expert: amateur away from home! I agree that sometimes it feels a little intimidating to know where to put / discuss stuff in the different forums. I figure this: put it out there, where you feel appropriate, and someone will pick it up and start the thread. I'll start one thread..... All you guys....... I need analog math problems to be submitted, so that when the TR20 is restored, we'll have simulations to run on the computer. I'll make a list of what computational modules we have so you know what to work with, i.e. integrators, DFG's, summers, etc. The plan is to have an XY recorder and XY scope for results output. As you saw, Evan becomes the safety net and guides us all in the right direction. As he self proclaims himself: "chief cat-herder". Bill Inderrieden In a message dated 11/12/2016 6:00:02 A.M.

Question about the various means of communications available to us. So I see a lot of infoage/camp evans/club related discussion here. But not a lot of technical q&a. On the VCFED website, there are various forums. Is that the right/best place for technical discussion and this is more for club-related activities? Do I have this right?
