I recently purchased what I believe would be called a Mits 300/25 with the rack, desk and supports. The table top is in reasonably, but not perfect, condition. It looks complete with an 8800b front panel and a turnkey board. And dual Pertec eight inch floppy disk drives all on rails. I believe I...

I've got this Radio Shack TRS-80 Model 1 working after replacing a chip in the Video RAM. I'm missing three key caps. 'X, ':' and 'BREAK'. Anyone have some spares? Is there a TRS-80 Bone yard? Wonder if a model 4 keyboard can be a Donner? The break key would be the wrong color though. I...

Back in the day the Vector Graphics Vector 1 S-100 computer was a favorite. Somehow I let it getaway. Now I'm wanting to find one again. I'll give it a good home. There is one like this image and also one with a 5" drive too. I'll consider either one. Back in the day I had one as pictured.

For use in my Imsai FIF project.... I'm attempting to run Martin's MEMON80 monitor from an AM2716DC EPROM placed at the top of a 64k COEX (Tanner/ Digital Research) Static RAM board. I burnt the EPROM with an ME2700. I put the ORG at F800 The eprom appears to match the .PRN. I took an educated...

Background I have a couple SSM VB1B video cards. I'll refer to them by their serial # The one I have working is 1133, the other I'll call SN BB because 'Bad Board' is etched with an electric pen on the foil near the SN which is blank. I'll start a separate thread with the BB sn most likely when...

I got a signon out of RDOS with my Cromemco Z-2D. Check it out here for some pictures. ZPU, (2) 16KZ RAM cards and a 4FDC. I have some possibly suitable drives, if my Siemens end up bad, from a Heathkit 3 drive enclosure. Not really wanting to break this up as I have an H8 I'd like to get...

I'm repairing a Solid State Music (SSM) IO4 card. I'm configuring it as an Altair 88-2SIO which I've accomplished previously on another board. I verified my cables and TeraTerm config using Martin's 88-2SIOJ card first. I cleaned up some questionable solder spots, checked voltages. The board...

A couple weeks ago I applied ECO 1000 - 1002, crowbar, to a recently acquired early Sol-20 with an original regulator board. With deRamps diagnostic assistance I replaced the TIP41, placed a 100k resistor in parallel with R12. Also replaced the power push button - there was a funky installed...

KerBroken. Dark screen of death. Nothing. Nada. Anybody want it for parts? I feel it's a sin to throw away computers. It might be a sin to keep them when you desperately want to reclaim space in your garage. I bought a collection from a guy on Craigslist because I wanted the Commodore Pet with...

The powerbook 145b seems to boot. I can hear the HD spin up then sounds like it's loading. I never see a desktop. The 100 seems dead. Hopefully these are worth a couple bucks as parts. Any takers? I hate to throw stuff away. But I'd really like to reclaim some space in the garage. When have...
