I recently rescued what appears to be most of a MAI Basic Four Terminal (model 7250, ~1980) from the local e-waste. The parts had been tossed loosely into a box, but they included the power supply, main board, CRT board and CRT. After a bit of testing, I found the power supply works perfectly...
*** Tektronix CPS 250 Triple Output Power Supply : $100 CONUS shipping included ***
I'm upgrading to a larger power supply, so this one needs to go! Used and slightly scuffed, but works great. Has two 20V/0.5A outputs (in independent mode) and one constant 5V/2A output. Will include a power...

After trying a couple different drives and updating my imaging workflow I have been able to recover much more data from the disks than before. I'll be uploading the results to Archive.org soon. Is just the disk image files fine for you or would you like the individual files extracted to a...
I still have the disks, but after some discussion on the WinWorld PC forum I decided not to upload any incomplete images (which was most of them).
If you'd like I can try re-imaging them with the latest Greaseweazel software and post what I get here for you.
