So Christmas is coming and I wanted to take a crack again at a few games like MS FilghtSim 1.0, Drol, DigDug to name a few. My AppleIIe
had a 4mhz Transwarp card that wouldn't cut FlightSim. A whopping one frame a second while sitting on the runway. This just wont do. So I ordered a
FastChip. Awesome card easy to setup. Love the variable speed control. First game to try LodeRunner. It loaded up but when I tried to play
things went south.
I went back to configure FastChip and wasn't able to access the setup routine. After many attempts I pulled all cards and powered up to the ] Prompt.
Tapped letter q and got qv as output. See picture below. Suspecting a keyboard or bad encoder chip I borrowed a keyboard assembly from a spare
unit hiding in the closet. Same thing, same output. So its a logicboard problem. Noting years of dust I scrubbed the board with denatured alchohol, q-tips,
and a couple of discolorations with a q-tip dipped in windex. Pulled and reseated all chips.
Powered it up and... Same thing still getting 2 for 1 on keyboard output. See picture below: starting with 1h, 2f, 3g... Any ideas what happened?
Unit boots, loads floppy but keyboard not so much now. By no means do I blame FastChip for this problem, or even think its related to this weirdness.
I checked voltages from PSU +5 = 5.1v +12v = +11.8v -5v=-4.0 -12v = -10.5v . I don't think the negative voltages could be causing issue but throwing it
in for review.
