Gregory's Serveri've used a similar technique to repair an Amiga 500. the idea is to 3d print the missing piece.

  @tubetime All this is making me miss my old Thinkpad 701 Butterfly. Damn that keyboard design was so neat. the operation won't start until the parallel port is ready--i had to pull the BUSY line low with a jumper, and now i instantly get this error! good luck figuring that one out  @tubetime @tubetime I'd really like the W variant to use external bubble memory just 'coz 1980s Intel. 🙂 But what the heck is it, only thing I can see is a Japan fab variant mentioned here: https://www.cpu-galaxy.at/cpu/Ram%20Rom%20Eprom/Microcontroller/Intel%208X196%20section.htm Even the 8XC196Lx Supplement PDF linked there does not mention it.  @tubetime *takes out a bucket of popcorn*    @tubetime I don’t know why I’m surprised that IBM used MCA in ThinkPads, but it does make sense! @tubetime Where's the code setting up the DMA channel so the parallel port doesn't read/send data from the weeds? :D |
it's a quick 20 minute print even with a 0.3mm nozzle, 0.12mm layer height, and 100% infill.
