 power supply from a tek 2465. sadly the fan motor bearing is worn out. (Tek made a fully custom 2-phase fan motor that's impossible to find)   what did i buy? well, i bought this Micro Switch keyboard. 53SW1-8. i'll have to find keycaps. apparently it uses 2SW keycaps. i picked up this Seagate ST-251N which is the SCSI version of the 251 drive I've reverse engineered. I haven't documented the control board in this one yet. and i got a type 2 planar for an IBM PS/2 Model 80. this one is meant to run a 386 at 20MHz. i could use it to upgrade my model 80 which has the slower type 1, 16MHz planar. (there's a whole story about the type 1 needing matched memory cycles and the type 2 not needing that)  @tubetime Weird place for the 7. Does it come from a keyboard with the numpad on the alphabetical keys? @tubetime so that's what it is! A friend of mine gave me a motherboard very similar, noting that there was almost no estàndard conector. I knew it was an IBM but never looked into it further than that. @tubetime I think I had one of those, I wish I had the audio recording of that thing booting into DOS 6.22  @tubetime Hall effect? Honeywell had some nice kryboards in the 80s.  @tubetime loving the "Z80 Inside" cards ... the popularity of older electronics based on a recently defunct processor is exciting.   @tubetime Given the magstripe - > Chip and Chip -> tap evolutions, there must be a ton of these credit card readers lying around. @tubetime I still don't need much more processing power than those machines offered.   @tubetime huhuh I understood that reference, and I think I know which thermostat you're referring to. Even I did a double take. I had one of these, that's a Z-158 if I'm guessing right. lovely systems, no motherboard just a bus connector to put all of the parts into. with a new PAL chip the memory board can take 256K DRAMs for a RAM disk, which was very exciting compared to running programs from floppies.  |
