I recently acquired a 1400FD with a bad PS. I was able to bodge a simple one together, but now it does not seem to want to read the floppy. The floppy cable seems to be very similar to a 1000 cable with +5V on several pins of the 34 pin connector, but attaching a known good floppy to a custom...

A ribbon cable would be difficult as the pin pattern on the DIN-96 connection is not excessively uniform. I think laying out a board would be more straightforward. In truth, I was a couple of hours of wire-wrapping for me. I had a couple of minor goofs to resolve, but nothing excessive. As...

I wire-wrapped mine. It's tedious, but for a one-off project it worked fine. The photos are on thingiverse. I had a DIN-96 connector that was wire-wrappable (~12mm long pins), and a ISA connector that I had de-soldered from an old motherboard. Not much else but follow the schematic. --bryan

@Mike1978 , I saw your question on Thingiverse. I have not don't anything but build and use mine. I briefly considered doing a PCB layout, but that's not my forte. A dual-card one would be possible, but I didn't do that to keep the size down. With 2 cards, the strength of the attachment...

I had tried to use the infrared link from the keyboard, but it's modulated at 40kHz and I only had IR modules at 38kHz I believe. I ended up using the wired interface and wrote some (really dumb) code to interface to it that way. The code is on github at...

Hi. I had a similar idea and was able to locate schematics at https://forum.classic-computing.de/forum/index.php?thread/16680-compaq-portable-ii-und-compaq-portable-386-expansion-unit-schaltplan-und-connect/ I created a simple bracket to hold the connectors for a wire-wrapped version here...

I created a simple T-shirt design, available here: https://www.spreadshirt.com/shop/design/fully+vaxenated+since+1977+mens+premium+t-shirt-D6163b4b2dc5b1108ab00c279?sellable=orNvQOAGMzIGRENoxypo-812-7

Hi, Years (20+) ago I was given a TI S1505 system that had no drives, but included the S1505 motherboard, a multidrop card and I think another serial card. I was able to briefly at the time get the firmware to give me some info, but not able to do much else. I _think_ it still works, but the...
