I tried out the Tandy 640x200 16 color driver for SCI 1 this morning using the LSL1 VGA remake. The result looks pretty nice, though as I expected this game is more or less unplayable on an 8 mhz 286. The fastest machines with this video mode would only be 10 mhz, so I doubt they would fair much …

Yep could shove an p24t pentium overdrive in there or And this is literally the only vintage CPU that I recommend overclocking. Every SX I have ever owned overclocks to the limits of the motherboards stability, might need a heat sync but 40 or 50 MHz is possible depending on how stable your board is …

Computers in the 90's were expensive and few people needed one. Why spend 3000 dollars on a compaq or a HP when you could spend 199$ on a SNES? It didn't make any sense.

It would be beyond my skills for sure, but at least in theory, wouldn't it be possible to hack a CGA monitor to bypass the TTL logic, Yeah, I know, it's sacrilege to mod increasingly rare CGA monitors, I get that. But it can be done in a way that would leave the TTL compatibility in tact, right? …
