Thanks, just trying to save some cash, F series seems to be a bit more available than the HC or HCT series chips Just for information, in case you are not aware of it: Do avoid HC chips for interfacing with TTL logic system (like the ISA bus). A TTL system expects a receiving chip to treat 2.1V as …

So I got the card in my hands, and notwithstanding my capture setup barfing a bit, the card does seem to deliver on very high if not 100% IBM CGA compatibility. https://www.youtube.com/watch?v=atWSy1o8CkE I think it might be possible to hack composite onto the card. Take a look at pin 61 and 62 of …

...substitute LS or F series chips in the build? Yes, you can. However, there might be timing problems if you mix F and LS series, so it is better to stick to only one type - LS or F Thanks, just trying to save some cash, F series seems to be a bit more available than the HC or HCT series chips

Ok, so that header on the Compaq board marked "speaker" I always assumed was a PC Speaker input? Yeah, it's actually an OUTPUT. So don't make my mistake if you buy one of these things. These cards DO NOT have a speaker input.

What speed MediaGXm are you using? Benchmark results for all GXm speeds are reported in the Ultimate 686 Benchmark Comparison. For example, the FPU ability of a GXm-266 is about that of a Pentium 133, while the ALU ability is similar to that of a Pentium 166. On the other hand, if you look at Quake …

Most of the chips used on these adaptor interposers were mobile parts …
