Bill, I've got extra 2716s (with some 2516s and 2616s sprinkled in), if that is close enough. Happy to contribute what I can. I'm in northern VA so shipping would be fast. -Jonathan

I am looking for 8 or so 1702A eproms if anyone has some for sale but I will buy more if the price is right. They do not have to be rare/ceramic. I will pay more for tested / readable. Please contact me privately if you have a tube of these avail via https://vintagecomputer.net/contact.cfm. I may also need 2708's. Shipping to Landenberg, PA. Thanks Bill Degnan

Bringing out Capsela Robot again!
by Jeffrey Brace 24 Nov '20

24 Nov '20

After running shows and helping with shows, I get to do my own exhibit and actually enjoy someone else's show! :-D I was asked to do an exhibit for the Virtual World Of Commodore 2020 on December 5. 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. If anyone is interested in doing a Commodore exhibit, sign up here: https://docs.google.com/forms/d/e/1FAIpQLSc7Wr7ajcAV-t6iswLy1CcnabRQkAjYght… More info on the show: https://www.tpug.ca/world-of-commodore/world-of- commodore-2020/ Here are pictures from the last time that I did the exhibit: https://drive.google.com/drive/folders/1Wus7obefZBDws1woX5p1szfNQZUXvLgq?us… -- ========================================= 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

Re: [vcf-midatlantic] Wanting to get into s100 homebrewing

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.

Bobby, Note back then that was the Wilmington Del. repair shop, now my business is located in Kennett Square, PA. Kennettclassic.com for hours and location. You'll need to make an appointment because I will need prep time to.set up the Compupro and terminal. Do you have 8" drive(s), cables and boot media?

Any terminal will work, or a computer running comm software. If you're going the comm software router, to start, avoid using a usb to serial adapter and try to use a true serial port until you're sure the computer is working with a serial terminal. I have used all kinds of things with a Compupro; Zenith, Just a question whether you need a null modem or not, I dont recall. Does it have the Interfacer card?
