Enrique Collado, could you expand on this? from APF_M1000.txt: CSS is connected to the PIA. It is set or reset with the bit 3 of 8193 when the bits 4 and 5...
Decided to play around with 8193 and 8194 to see what I could figure out. And how it worked on actual hardware. Managed to crash the system several times... ...
Apparently, VDG INT/EXT is connected through PIA 8194, bit 5 (32). As pokeing 8194,32 gives me SG6 and the non existent External Text. Much like SG6 on a COCO....

In my M-1000 INT/EXT(Pin 31) was connected to VSS(Pin 1). Perhaps yours is another version. In my M1000 board, the version is APF M100 REV3 PN DA-01 JUL6 '78....
Since this group started I've had keywords that would spot an APF MP 1000 console. Well, one came up the other day (the first one in quite a few months). I...

Hey Adam! Even though the cart boxes are generic I've never seen so many of them and all those instructions. That looks like the bottom styrofoam to the...

Yeah, unless you need all those carts you can probably get a better deal on another one later. I'd wait for one that is tested since Ebay untested usually...
