74XX Arcade Repair

Arcade repair, retro gaming, vintage computing, synth-o-sizing!

Got all the pieces together to get this IBM 5160 up in color! Found this Commodore 1902A locally which does digital RGB, and bought an EGA card from eBay. This is Black Cauldron from Sierra, the "booter" version which doesn't need DOS, in glorious 4-color CGA. What EGA game should I try?

Today's repair.. My own dang Centipede! The monitor chassis died they other day. One minute it was fine, the next minute, no high voltage. It was one of those cheapy AliExpress specials, so I just replaced it.

Speaking of FDS, my copy of Legend of Zelda is quite odd. It's a blue disk, with a generic label. But the case has a possibly-legit spine with "ファミコン通信" at the bottom, a legit sticker on the back, and a US style hand drawn cover on the front, which is glued on. Can't tell what's under it.

Realized I had maybe one of the rarest arcade marquees around, and it's unused. The layer on the front was cemented on and I'm getting it off now with some water and heat. Can anyone guess what it is?

For some reason I was looking up the Beavis and Butthead point-and-click games and was surprised to find they weren't all made by the same dev. The Illusions Gaming Company might have had the most esoteric cross section of games I can think of:

One more repair to round out the evening. Konami's blades of steel. Bet you didn't know it was an arcade game? Well I'm counting on that for my next big video. This one had no sound due to a good ol' fashion bad Fujitsu logic chip. When we see the 'F' we say "Ffff..."

Today's repair - Rally X. This one had only basic blocky shapes and messed up color. The graphics ROM on the CPU board (go figure) was dead, no output. One PROM had one dead output giving weird colors. A good chance to use one of my FLAP adapters, which lets you use a cheap flash chip in its place.
