Personally I have solved the problem through the acquisition of a 17" CRT screen. It handles all use cases (DOS, early Windows games) perfectly. Nonetheless darry's suggestion is excellent for those who don't have enough room or can't find a CRT.

Not to my knowledge, but if your intent is Windows gaming, you can get a pixel perfect doubled 640x480 by using an nVIDIA card and selecting the option that preserves the ratio (hence 1280x1024 is sent to the monitor, but really 1280x960 is shown with black bars above and below).

I did Scythifuge. They work without issues at 70 Hz without frame skipping. However you will need the OSSC if you want to avoid pixel doubling artifacts (640x400 incorrectly sampled by the monitor as 720x400). This is a problem common to all LCD monitors I've tested. Note that this pixel doubling …

If you need a parallel port, there are many socket 775 boards of that era that have a native port, such as the (G33) ASUS P5K-VM https://www.cpu-upgrade.com/mb-ASUS/P5K-VM.html or the (P965) Asrock 4Core1333-Viiv https://www.cpu-upgrade.com/mb-ASRock/4Core1333-Viiv.html .

If you search for IMG31ISA, you'll find a socket 775 motherboard with one ISA slot. I can't vouch for it but you'll get SSE2.

If OP really wants ISA, then I suppose the Abit KT7A could fit the bill. A 2 GHz Athlon XP works great, albeit the lack of SSE2 restrict it from running more modern software.

I would suggest avoiding Haswell and sticking to Ivy bridge: - Ivy has officiel XP drivers, especially the integrated graphics part - Ivy is also the oldest platform officially supported by Windows 10 - Haswell has removed some legacy stuff (eg. see https://forums.virtualbox.org/viewtopic.php?f=2&t= …

Thanks a lot. I tried Mickey's 123 (enhanced) with L1 disabled but did not hear any clicks/pops. The sound effects were fine although of a low quality. Maybe using the CT2290 in a relatively modern system (Athlon XP) fixes the issue?

I had some errors with memtest86+ on a Abit KT7A that manifested at the 512 MB boundary. I'm not sure which test it was, but in normal usage I never had any issue. You could try to do a cpu/memory intensive task such as compiling a large piece of software like the Linux kernel; if it runs correctly, …

Or just buy a board that doesn't have these caps. Or only replace the ones that are actually faulty. Blindly replacing everything is just bad practice and shouldn't be encouraged. Diagnostics first, replacements second. He should replace all power components as well because they fail just as many …

Great post! Could you kindly share your technique for replacing caps? I have recapped a KT7A but it was a very difficult process , in particular the removal of the old capacitors.

Having tested the CT2290 with UFO enemy unknown, there are graphical glitches and the pops are loud and clear at the CPUs original speed (here an Athlon XP @ 1666 MHz) when a mission starts. However after L1 is disabled the graphical glitches and pops disappear completely. Please keep in mind I'm …

With single cycle/single cycle I have some faint noise added, but nothing dramatically bad. I'm not hearing any loud pop or click sound when the sample loops. …

Sounds awesome BeastOfSoda. You might also be interested in Resound OPL3 which could potentially be easier to setup than a full CT2230 and still provide genuine OPL3 FM. Sadly it seems out of stock ATM. OTOH the Resound 2 OPL3 is available but has less features (in particular, no internal oscillator …

The opamp is only one part of the equation. The filtering of electrical noise from the rest of the system, in particular CPU activity, is quite important. I'm not expert on the matter, but the simplest is to buy the card and return it if you think the noise is not acceptable. A good way of testing …
