Thank you! I had been using PCem since v12, where I started to experience all those nostalgic BIOSs, reminding me of my first ever 486 PC, that it made me start building vintage PCs in 2017! I previously authored DOSBox patches in 2012 to 2013. I still continue to use DOSBox, PCem, and VMware, but I …

Sound card wise, I use an Asus Xonar D1 PCI in my Asus workstation, and an Asus Xonar U7 USB for my Mac, which I had since 2010 and 2015 respectively. Monitor wise, I use the Audioengine A2 speakers and Focus Spirit headphones, which I had in 2014 and 2016 respectively.

woah holy crap that's an awesome job desoldering! Your next task is to desolder a modern MacBook... Thank you. This gave me some experience desoldering through-the-hole devices. The next tool is a hot air station. Maybe I could upgrade a BGA soldered CPU in my MacBook? Not going to be easy, but I …

As for the original one that I bought over 18 months ago, I had a problem with the disk presence sensor that was sometimes sticking to on, despite correcting the jumper setting, causing the system to think that there is a disk present when in fact there is none, or the old disk is still present …

As below, you can see that one of the jumper settings is different, as both drives report disk change / drive ready differently to the system, despite both being TEAC FD-235J, but with different suffixes (3653 and 5670) to the model.

I have not been updating the base DOSBox build ever since, especially …

Having searched single board computers, I suppose I could get an ISA back plane, mount the main SBC, Trident video card, I/O card, sound card, etc., and see if I could get a complete 486 PC? Has anyone had any experience with SBCs? I am relatively confident that Tseng card was sold by JDR Computers …
