I would probably try something less harsh on pots to start, not knowing what they’re made of. Try fader lube if you can get it.

Small update, a little disappointing but at least there is some progress on my sickly 8425SA. The RetroHackShack video helped a lot on figuring out what was going on. Thanks a lot for the help! I replaced the burned resistor at R45 (1Ω, 1%) but I had to chop up the Molex power connector to get...

I was actually just reading this article about 90° trace angles being just fine: https://www.nwengineeringllc.com/article/right-angle-pcb-traces-its-time-to-kill-the-myths.php It sounds like making traces consistent, short, and avoiding vias matters way more for reflections.

Based on the "sw" headers at the bottom, I suspect this was indeed meant to be used with a switch to select cards.. neat!

Sure, please do if it’s not too much trouble. If nothing else, having good photos of a working one might help someone in the future piece together a fix.

I haven’t tried dumping GALs before, but it would be a fun reason to build a DuPAL. Maybe a good project in a few months. Having three cards in an LC would be amazing, although I wonder if INITs and drivers would need to be patched as they probably make the assumption they’re all alone in the...

I’d be really curious to see some good pictures of this board. It’s not clear to me how they’d be able to do addressable PDS slots: I think the MicroMac one gets away with it because they assume one of the two cards is always an accelerator & therefore runs the bus.

I wonder how they cut such a precise slot into the front of the machine. It doesn't even look like the edges melted.

Not much to add other than I desoldered/destroyed the Molex connector so I could get at both of the joints for the visibly burned R45 resistor. It's a DALE-branded 1Ω 1% resistor, and I'm guessing it's meant to be a pretty expensive precision part. It looks like the same part from the Hack Shack...

I finally figured out that my SE FDHD wasn't starting ("flupping," or the PSU going into protection) because of the MiniScribe 8425SA that came with it. I followed my nose until I isolated it as the source of the burned component(s). For some reason, possibly stubbornness, I want to try and...

That chassis looks great. Are you planning to plate/coat it, or just paint?

I do see a lot of broken PowerBook cables, and I’m scared of opening and closing my eMate, so this is a great service you’re providing. Do flex cables get dramatically cheaper with a larger quantity? They have always seemed very expensive in small shots. One of my friends is also having...

Based on squinting at their respective analogue boards, I suspect there's a lot of overlap between the Colour Classic AB and a 9" Sony PVM. I do have a CC with some very scorched Zener diodes on the AB that I could probably try reversing, but analogue stuff is not my specialty.

Could be one of those right-to-left mistakes, where one person is counting from the left side of a female connector, but the other person is counting from the left side of a male connector.

I set up a configuration for the NEC PC-6601SR (4-bit digital RGBI) and it worked really well, although I still need to figure out how to make a palette. If you already have the gear (pis and the cpld are in short supply these days) it would be my first stop for anything like this from now on...

Interesting problem. It hopefully won't take too much time to take the keyboard apart and check that ADB jack for a broken solder joint, debris in the connector, or even a cracked shield.

Great work so far! Does the “ROM B” button allow you to select a second ROM with more machines on it?

That’s amazing: structural solder mask. I can’t even get the stuff to go smoothly over trace repairs!

Time to benchmark drag race it against a 6100. Fantastic work. Does it get hot?
