Do you order from small business online stores? I'm thinking Unicorn Electronics, TexElec, ReActiveMicro. Do you order from medium-size stores? Like Jameco, maybe Monoprice, Parts Express. My guess is no, aside from unique items that are only available at a specific store. Free shipping...

Wide-format Xerox 630 printer. Has setups for single-page and tractor feed paper. Works, tested with a Xerox II 820 More photos: https://www.intergalacticmicro.com/files/index.php/s/6VJwm49xdrkghpq For pickup only at VCF Midwest this year, or local pickup from Reed City, MI $150 OBO Thanks...

Works great! Boots single-sided and double-sided disk images from the Gotek. Physical drive is a single-sided model, works well, we tested formatting, reading, writing. We were able to copy single-sided disks from the Gotek to physical. 2 CP/M boot disks are included. Screen is nice and crisp...

I'm working on getting one up and going - possibly a ROM or 2 are in the wrong positions or have invalid. Would be nice to confirm. Thanks! Matt

Just throwing this out there - Executive Summary: I have tons of ICs, Caps, Resistors, and stuff. Most of it has little value, but might inspire someones project. I'll add a grid of a random list of maybe 1% of it to a reply here Want to mess with a 16-bit DSP? Old school A to D? Dual-port...

Hello all, I'm working on a Tandy 1000SL board that's missing an ODD bits ROM - SU4 / HU2 My board is fit with the SU pinout ROM sockets. My SU3 / HU1 ROM does seem to appear OK, I have a dump of that if it's needed. Thanks much! Matt

USE AT YOUR OWN RISK! It's not really good enough to release, but I decided, eh, I don't care. :) https://github.com/IntergalacticMicrosystems/SSDW A way of sending a raw diskette image over serial to a vintage 8086+ DOS PC. Track by track, written to disk immediately, so it's quite...

I have a continuous rotating busload of old stuff to run long processes on (system diag, burn-in, hard drive wiping, Spinrite, system setups, etc.) Mostly 8086 to Pentium PCs, some Apple II series, some Classic Mac, C64, and others. I'm hoping to find one that is robust as far as handing...

See photos here: https://www.intergalacticmicro.com/files/index.php/s/wRlU28JqF0kS9Cn I'll most likely be recycling this stuff in a week or 2. Some dirty, some water damage. If anyone needs anything from this pile, I'll make you a deal :)

Just curious - is there a ROM dump of the microcontroller code around? Looks like it was a mask-programmed chip - so possibly it would be from a de-cap of one if there isn't a "Test" mode that could read the code. Such cool little plotters. I can't imagine they were reliable, looking at the...

Not me - but looks interesting if you're local - saw this on FB "If you’re near Nashville, TN on Saturday, come on by the huge vintage computer sale at Franklin Ewaste. 9am-3pm Saturday. 234 5Th Ave N. Franklin, TN." https://www.facebook.com/marketplace/item/5016078091837014

The SYSCOM II Apple II+ clone I've been working on is weird. The ROMs data lines are wired like this: CPU D0 -- ROM D7 CPU D1 -- ROM D1 CPU D2 -- ROM D2 CPU D3 -- ROM D4 CPU D4 -- ROM D3 CPU D5 -- ROM D5 CPU D6 -- ROM D6 CPU D7 -- ROM D0 Maybe they did this on purpose to avoid copyright...

I'm not sure what to call it - but I'm thinking of something that connects to the pins of a 40-pin CPU in-circuit. Maybe uses an IC test clip to make the connection. Maybe with an FPGA with 5v logic level converters. In theory something like this could: Emulate ROM, IO, Disk, network, even...

Do some machines (or ROMs?) not support cassette? The case has the labelled ports. ROMs could be non-stock At the basic ] prompt: LOAD, SAVE, LOAD "TEST" - all give a ?SYNTAX ERROR immediately In the CALL -151 monitor: 2000.62E7R - returns immediately, no error Same with any xxxx.xxxxR or...

Not mine, just happened to notice it this morning ... http://battlecreek.craigslist.org/sys/5008416579.html circa 1975 Historical Vintage Computer. Powers up and Runs. Just this Box. No Docs. I'll accept any reasonable offer.

A few items, will be listing more this weekend. If you buy something, mention this post in a "Request invoice" email and I'll discount it 25% Make an offer if you see something you need :) http://www.ebay.com/sch/westveld/m.html?_ipg=50 I'll probably be listing these this weekend: Tandy 1000...

I remember them advertizing in Circuit Cellar back in the day, assuming they are gone now... aka Vintage :) Tiny PC and PC-ON-A-CHIP looked interesting: http://www.geocities.ws/megamvs/

My favorite local recycler had a pile of stuff - "package deal - but you have to take all of it" :) Paid a little too much for the actual items I wanted - so I'll try and get a little from the rest - 2 x TRS80 4p One boots fine, keyboard and screen seem good. (couldn't get a good photo of...
