RetroChallenge 2023/10 - Applix1616 restoration/documentation

Short weekend update:

Was looking at how to mount the BlueSCSI and found that 2 case holes right in front of the motherboard are exactly 68mm apart, which just so happens to match 2 of the holes in the BlueSCSI V2 Desktop. There’s also just enough room between the BlueSCSI and the Motherboard for everything to fit nicely. As long as I use the shortest nylon stand-offs I have, any cards in the motherboard slots should clear the top of the BlueSCSI easily. I’ll put a 3rd standoff on the BlueSCSI but not screwed into the case so that it doesn’t wobble on just the 2 stand-offs.

Inside of case with holes circled in Red:

That said, while setting up the the BlueSCSI V2 Desktop with mounting posts ready to go into the case (just after installing the latest firmware), I noticed that one of the chips fell off the BlueSCSI board.

Have contacted the supplier on Saturday afternoon by email, and they got back to me in a few hours. Going to send it back to them on Monday. They’ll sort it out then get it back to me, no charge. Fortunately they’re in Sydney, so turn-around won’t be too long. It was supplied as a kit (with all the SMD parts already mounted on the board), so it’s hard to test till it’s assembled. Very happy with their service to resolve this, though of course any delay is not ideal.

Cut some of the patching plates on the laser cutter at Canberra Makerspace today and tapped them for M3 screws. Mounted them on the case and used nylon screws as I’m still low on the original screws. Also put an 80mm fan in the case as well. The plates are 3mm red acrylic, which I found in the scrap bin at the Makerspace. The red is very similar to the 1616 in the Applix logo, so it seems to go well with the case.

Back of the case with the plates installed:

Cut a plate to cover up the card slot holes (since the cards don’t have brackets on them), but I got the holes in the wrong place, so will need to give it another go.

There’s a place for a 6 pin header on the motherboard (near the power connector) that has GND, +12V, -5V, -12V, +5V and GND (repeated) on it. I should be able to run the fan off the GND and +12V pins. If needed, I could run the BlueSCSI off the +5V and GND pins, though in theory the BlueSCSI should be able to work on the SCSI bus termination power.

May also have a suitable monitor coming to me. Just waiting to find out when I might end up with it.
