USB Floppies that are flexible? Cleaning a 3.5" drive?
by John Heritage 08 Dec '20

08 Dec '20

Hey folks, two asks -- I'm looking for advice: Are there any USB or external floppy drive arrangements that are flexible like internal floppy drives for allowing formatting and/or reading of unusual sector sizes or formats? Ex: 800KB Atari ST floppies and PC DOS disks formatted in unusual sizes .. Second question is -what is the easiest way to clean the heads on a 3.5" floppy? If I have a bunch of 'suspect' floppies that I want to clean the head between every disk it seems a little painful to disassemble the drive enough to see the heads and clean. Are there any alternatives? (I'm used to 5.25" drives where there's often enough space in there to wipe without disassembly). Maybe there's a good (modern) source of 3.5" cleaning floppies? (P.S. I have a K6-3+ PC I can put a fresh OS on so I may be cleaning a legacy 3.5" drive instead of a USB floppy). Thanks! John

I for one really wanted to learn more from others more about the methodology of old computer repair, electronics, and testing. I wanted to learn about S-100 and DEC/PDP tech, which was before my time. We did a lot more with memory maps and program listings. We played around with in-circuit emulators too. I was always impressed with how some of the folks could trace a board without a schematic to troubleshoot it. Back in the mid 2000's there were few Youtube how to videos and a lot of the knowledge that's easy to find today had to be re-learned and re-documented for the vintage computer hobbyist. It was much harder to find manuals and documentation and we used to meet just to share paper copies of manuals and hard to find parts at earlier MARCH workshops. We were more focused on S-100, diskdrives and older stuff then. Anything older than an IBM PC. I don't agree that you can easily teach old-school at a VCF unless you disallow use of the internet and electronic copies of manuals to be used to tackle a problem. In other words, you'd have to "make it hard again" to really teach what it was like. That's the kind of hacking you did with Heathkit manuals and why good manuals were the key to their business. The accomplishments at today's VCF workshops are equally impressive perhaps but tools are a mix of old and new. The nature of diagnosis and repair has evolved away from purely vintage/old school ways. Bill

Museum Report 2020-12-06
by Jeffrey Brace 06 Dec '20

06 Dec '20

After a few weeks of little to no visitors we had 12 visitors today. Four groups of 2 and a family of 5. One adult had high interest in the microchip exhibit because she used to verify the labeling on them by sight. She claimed that is why her eyesight went bad from squirting to look at the lettering on microchips at a factory in Hazlet. She also liked the TRS-80 Model 100. She had lots of questions about the different computers and really enjoyed them. There were others with mild interest and the family of 5 had 4 daughters who really enjoyed the paint programs. The father enjoyed trying basic on different computers. Looks like the cooler weather is bringing back the visitors after a unseasonably warm October and November. -- ========================================= Jeff Brace Vice President & Board Member Vintage Computer Festival East Show-runner Vintage Computer Federation is a 501c3 charity http://www.vcfed.org/ jeffrey(a)vcfed.org cell: 732-759-1783

>It would be nice if I could get it to boot from the hard drive. I have an Amiga 2500 and I run a SCSI2SD card in it. It's attached to the SCSI controller that came in it. One issue is that the SCSI2SD boots slower than the Amiga trying to access it, so I wait a few seconds then do Amiga-Amiga-Control or whatever the reboot three finger salute is. BUT... get this. With WinUAE emulator on Windows laptop, I can stuff that SD card in it and boot the emulator from the same SD card that runs the Amiga. I copied all the WHDLoad stuff in via that means, DiskMash unitilies (DMS files) and other goodies. It's very convienient for moving stuff onto the system. IIRC I setup the SCSI2SD to look like 4 2GB disks or something, and I used the diskutil program? to prep em. Listen to see if the disks are spinning. If not a thunk against the table should fix. > Also after opening the unit I found the battery back up leaked on the > board > and cleaned that up, but I haven’t turned it on yet to make sure Good news that it still works hopefully!

All Amiga Keyboards are Amiga only. The 2000 and 3000 share keyboards. The 1000 and the 4000 are their own kind. None are compatible with AT keyboards. Same with mice. I would invest in one of the Amiga to USB converts for Keyboard and mouse available on ebay, as the A2000 keyboards are expensive and may have issues due to age. I would also pick up a Gotek floppy emulator for the A2000, as the drives are not compatible with anything and you need a working Amiga to make disks. With a Gotek you can load ADF (disk files) onto USB sticks and boot those as emulated floppies. You can find versions of Workbench in ADF format floating around. I have actual floppies but I just recently restored my A2000 and found a few of the floppies are bad. I ended up installing via Gotek onto a SCSI2SD adapter used as the hardrive. Also the Amiga Explorer was something I used- it allows you to push files from a PC via Serial port onto the Amiga (everything can't be turned into a ADF disk file...) https://www.amigaforever.com/ae/ https://www.everythingamiga.com/2017/05/amiga-explorer-pc-to-amiga-data-tra… You'll also need/want a hardrive for the A2000, which means a Hardrive card/scsi controller: https://www.ebay.com/itm/Vintage-Commodore-Amiga-A2091-SCSI-Hard-Drive-Cont… If you don't already have one in there.

No problem I knew that you were Commodore guy and I figured you had a “graduated” to Amiga at some point.

Of course now I wish I had them and I would still have the software, well that’s how things go right? Do you have any idea when we will be going back to doing workshops?

Ordering Snark Barker MCA (Sound Boaster clone) PCBs -- Want One?
by Alexander Jacocks 30 Nov '20

30 Nov '20

All, I'm in the process of ordering PCBs for the Snark Barker MCA (microchannel), which was just announced, here: https://twitter.com/TubeTimeUS/status/1333123576346468352 The design files and BOM can be found here: https://github.com/schlae/snark-barker-mca I'll be ordering from PCBway, who does gold fingers, so that the boards will be able to be able to be repeatedly inserted, without wearing out the contacts. Is anyone else interested? The cost (at quantity 5) would be about $34+shipping, per PCB. The cost should go down with a bigger order, should more than 4 others want boards. I could probably be convinced to make the parts order, as well, if folks want. Thanks! - Alex

I was specifically asked to do my C64 Capsela Robot exhibit that I did about 5 years ago for World Maker Faire. I agreed. It will be fun to bring up this project again and to build a new robot. I may also show off in more detail the 80's Bedroom Exhibit in our museum which features a C64 and The Print Shop.

Hi Randy, Good eye! I built it from a NOS bare board. It almost worked the first time. I had a tiny solder bridge between 2 traces which wasn’t that hard to do as there is no solder mask. It is one of the few S-100 boards I had built that wasn’t solder masked. I guess I got complacent. I also have the BYT-8 front panel board but I have been looking for the enclosure for years. I may wind up getting one fabbed down the road if I don’t find one.

VIC-20-Hyper-Expander
by Christian Liendo 24 Nov '20

24 Nov '20

I saw this on facebook and I figured some people would be interested https://github.com/svenpetersen1965/VIC-20-Hyper-Expander The Hyper Expander is a cartridge for the Commodore VIC-20, which provides up to 16kB EPROM and up to 32kB RAM. It is a super-set of the original Commodore VIC-1211A Super Expander, which provides only 3k of RAM. The Hyper Expander can hold up to two 27C512 EPROMs, the 8k memory bank of both EPROMs (A13...A15) can be selected for both EPROMs. The same selection applies to both of them. Each EPROM (IC1 and IC2) can be jumpered to two chip selects. That is BLK2 or BLK5 for IC1 and BLK1 or BLK3 for IC2. The RAM is a 32kB 62256 type static RAM. The memory is divided into four banks. A 74LS148 decodes the active chip selects to one of each memory bank. The used chip selects can be configured with JP5 and JP4.

Back then, it was on the bench at work (and IIRC, they paid $250 for it new, in 1981-82). When the company folded in 1993, I bought out the stock and bench and continued to support our (few remaining) customers for the next 1-2 years. I've replaced the heater once and the thermostat unit once in those 36 years. I could use a new strain-relief grommet on the cord but it's been fine for years with gentle handling. About the only thing that could replace this battleship is a nice Hakko with a sheaf of SMT tips. -ethan

Dang they don't make them like they used to ...
by Neil Cherry 19 Nov '20

19 Nov '20

So my POS 35 year old Weller workstation that I got out of the back of the Computer Shopper for $25 shipped has developed a crack in the heat guard sleeve. I mean really I spent good money on this and it only lasted 35 years. I want a refund! ;-) I think I can fix the crack with some heat shrink tubing. BTW if anyone has ever seen my Weller they'd wonder why I still have it. It looks like someone took a BB gun to it. It's looked that way for the last 35 years. I do need to take some epoxy to a few things to fix some of the broken parts but it still works and the tip is good (small chisel tip). The tip was bought new when I got the Weller. I think it cost more than the Weller. I also have the original tip. It was a bit worn but usable. I wonder if my Hako will last that long. Might I never use it. ;-) -- 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

Re: [vcf-midatlantic] With New COVID Restrictions, Is Museum Affected?
by Jeffrey Brace 17 Nov '20

17 Nov '20

Bill, It's not likely that InfoAge Museum will shutdown unless ordered by the Governor. Apart from a few occasions that brought in a lot of people at one time such as scheduled boy scout tours or a Jewish holiday there haven't been too many visitors at one time. Visitors have trickled in at a slow pace over the last few months. Also the protocols that we have been using already limit people to 10 at a time in a museum room. So even with the 10 person per room restrictions, InfoAge (and VCF) are already following them and have been following them since re-opening in June. I would expect that unless there is a order or some problem, InfoAge won't shutdown. They are already following strict protocols such as limiting the number of people, requiring everyone to wear a mask, taking temperatures at the front desk, taking down contact tracing info, hand sanitizer, etc. It is up to IA to make the call. In the VCF museum we are already limiting people to 10 inside our museum and following all protocols for mask wearing, temperature taking, and sanitizing.

I'm sorry to report that due to new guidelines in New Jersey Festivus is cancelled for this year :( But don't lose heart, I'm hoping to do a Summer Festivus if conditions permit. So stay tuned for that. The steering committee will still be announcing the two new Steering Committee members during that weekend. We will let everyone know the time and method of announcement.

Festivus and Covid-19
by Jeffrey Brace 16 Nov '20

16 Nov '20

So I'm currently monitoring the spike in cases in NJ and in the region as well as the guidelines. As of today Festivus is still on. The current guidelines are: ******** General indoor gatherings must be limited to 25 people or 25% of a room's capacity -- whichever number is lower. All attendees at indoor gatherings must wear face coverings and stay six feet apart. ******** The plan that I have will follow these guidelines. If the guidelines change to something less (i.e. no more than 10), then I will have to cancel. I will make a call by December 7. Festivus is scheduled for December 12 & 13. Even if I cancel it, there is no reason why I can't reschedule it to July or any other month. It might even work out better for some people. -- ========================================= Jeff Brace Vice President & Board Member Vintage Computer Festival East Show-runner Vintage Computer Federation is a 501c3 charity http://www.vcfed.org/ jeffrey(a)vcfed.org cell: 732-759-1783

Micromint MPX-16 technical manual
by Richard Cini 15 Nov '20

15 Nov '20

All – I found a Micromint MPX-16 motherboard in my attic yesterday. I know back in 2002, I traded away one in the enclosure and it had the technical manual, but strangely I didn’t scan it for some reason. Now, I’d like to see if this board I have works. The magazine article gets most of the way there, but what’s missing is the DIP switch settings. I’ve made some guesses based on the source code for the ROM, but the actual manual would help. Bitsavers doesn’t have it, unfortunately. Thanks! Rich -- Rich Cini http://www.classiccmp.org/cini http://www.classiccmp.org/altair32
