DAMN, I broke the backplate cover when putting it back because I didn't lock the logic board handle back up :-( More UHU Plast… Yeah, should be ok.

Some measurements for later…

Not really sure where to go from there, don't have experience with them.

Didn't have the time for a video but I took some pics of my Performa 5400/180 Black, which was in a box for some years… Also gave me an idea for some future hardware stuff…

I guess we'll have to fake ones with a 2x20 and 2x30… bleh 🤷‍♂️

Aaaand of course Samtec doesn't make the connector I want non-keyed for 2x50 pins… why??? 😭

Oh the bomarc schematics have the full pinout for the 68k connector.

For Marchintosh I dug out this nice black Performa 5400/180 (not DE actually) from the cardboard box it was in the last 10 years or so for a quick checkup… It seems I actually never opened it, and I broke a clip from the backplate cover, and some of the melted bits holding the shield, which...

Not really, even plugging it wrong shouldn't do much damage, I mean even it it shorted the HDD LED output to ground it wouldn't fry the transistor there… You could still check the transistors around (9, 10, 11) for working junctions…

Ah ok so it's the logic board that is failing, not this gear. Or did it work before you tried it?

Are you sure you wired in the correct order? The pins are out-of-order on the schematics, although they also are for J20, so either it's ok or it's all reversed. Does it work without it connected? Did you try just plugging the LED or just the speaker wires separately?

Cool. I wonder if it'd help with those pesky keyboard membranes, the conductive trace melts way below normal soldering iron temperatures…

Oh cool I was thinking it should be possible, one less thing to add to my TODO list 🙃 Although I wonder how they handle bus arbitration, IIRC regular 6502 don't have the signals to suspend them… Or do they halt the clock or something?

Videos are now available here and here. Enjoy!

ORIC \o/

I definitely need to complete a first batch of my AAUI2AUI adapter, maybe film it and time-compress it, so I can post a 2nd video on my yt channel 😅

We start in 30min! Gee… 🏃‍♂️

CET (GMT+1)

See you there tomorrow!
