From what you've described, and since you're seeing the CMOS battery errors, it shouldn't be a Power On Password - that one's easy to solve by clearing the CMOS (remove CMOS battery). There's also a supervisor password which is stored securely on an EEPROM inside the laptop which you can't just …

It's tough honestly. There were a lot of big changes going on with laptop display technology through the mid 90s, which stabilised around 2000 - where TFTs (TN panels :)) and 3.3 LVDS signalling became quite standard. The mid-90s laptops can be DSTN (which has a couple of different types) or TFT, …

I like the OLED idea :) Using a white OLED screen, you can just print up a custom mask with some opaque black PETG and some moderately transparent green or red PETG as the LED diffuser, that should give a very similar look to the old style ones if both parts are printed with a small nozzlem or resin …

It's great that you included an extra row of pins to remote locate the buttons, rotary encoder and screen, those could go really well in a 3.5" bay 😀 It may be good to have that as a separate build option so they're not duplicated?

I think that's honestly a fairly recent post to reply to, compared to some posts on this forum and it's not off topic. So personally I would ask him in there, in your situation. It's a weird description of his problem and 2x strange that it matches your problem.

What kind of microcontroller? There are a few with USB host support that could work at this point. I was thinking a Pi Pico would work well for it, people have that working with USB keyboard input and it's easily available.

Nice, there needs to be something easily available for people to be able to use their Pi 3/4 as an MT-32 / midi module, but right now there isn't one that's readily available for people to use. Good that it's got the DAC integrated and what looks like the octocoupler. 😀

Thanks for the pictures! I recently bought the same Compaq 1.4GHz for my Tualatin setup but could not get the heatsink to come off, good to know that it might move with some heat 😀 I was stuck using the heatsink it came with, which might work, but it's pretty basic and hard to mount a fan to.

Does your setup have the -5v line? The SGBXII/Reveal SC100 is one of the few cards that I have that needs -5v. The shot of the back of your card suggests it does too. I thought mine was broken with working FM until I added the -5v line to my test setup, then it started working. But I don't recall …

Hey I recently had a very very similar issue with my strange soundblaster clone card, it could make digital audio but FM audio was near silent.
