The A500 is great for non-AGA games. It will play hundreds of titles as-is. There are lots of cheap accelerator options for it as well. Pistorm, HC508, ACA500, Vampire, Terriblefire TF534/536, Classic 520, etc. There are tons of different ways to expand the RAM, Chip RAM, CPU, hard disks, and all …

I have to setup a few different test rigs to test the two cards soon. I have one more work trip to go on this coming week, then I should be free for more play time after that.

Not really sure of many alternatives in that small form factor. Maybe a Sony Vaio P or UX, GPD Micro PC, or OQO? There's also Aliexpress packed with all sorts of mini-PC's like the One Netbook One series. If you went Linux/Android and modern, there are options like the Gemini PDA and Lisperati 1000. …

Vinyl/plastic dye works great as well, and it won't chip off.

Look at the part number on the RAM. Pull up the datasheet for that particular RAM. Search for equivalents. You likely won't find modern made equivalent chips, so you'll have to source it new old stock, or used off other hardware.

I remember PC Chips back in the day. Not many people here in the US bought them. It was mostly used by mom & pop computer shops to make super cheap pre-builts in lower income areas. Then the high failure rates caused them to abandon using that brand. I specifically remember the stigma of that brand …

Only thing I can see off in the pic is on RAM chip bottom right of the fan, left row of pins, right in the middle, check that isn't a blob/flake of something conductive. Looks to me like that pin is broken away from the pad, shifted downward toward the gold finger side of the card. It is definitely …

You'll want to boot up a DOS graphics mode test first to confirm for sure it isn't working in text modes. Also test both Windows and DOS 3D applications/games. Try different drivers. Try different refresh rates and resolutions in Windows. Try a different cable and different monitor. But if it is a …

Measure at the ISA slot with a multimeter to confirm it. Some boards may have a linear voltage regular installed to provide -5VDC, as rare as it might be.

99%+ of ISA slots you'll be putting an Adlib in will have phosphor bronze mating pins. It is corrosion/oxidation tolerant to lead and tin -- of course tin because it is partly made of tin itself. Also, lead is often melted in with it on purpose to give it better casting ability and flexible …

Use a RGB2HDMI if you want to hook up MDA to a modern monitor. By far it is the cheapest and best working solution.

Of course going directly into the CRT's circuitry would work, if you wanted to tear apart the TV and trace it down. Most people don't want to do that though.

You'll be extremely lucky if the tape drive actually works. We run the Compaq DDS3 drives at work in our Alpha Servers and all of them have failed.. and all of the replacement drives have failed. I wouldn't be too worried about the DDS3 tapes themselves. They are pretty reliable and I've pulled 15 …
