All ‹ I spent most of yesterday trying to get some sort of 8/16-bit hybrid system working using both new S100 Computers boards and some vintage stuff. The closest I came to having it working was the following: RAM22 (8/16-bit), SCP-200 8086, MSDOS Support (for the ROM) and my SSM IO4 serial card. In that case, I can get only console output ‹ the monitor will not receive input. I suspect maybe that the 16-bit data buss is causing the problem, but who knows.
So, I stripped the system down to the SSM serial card, the RAM22, and the S100 8088 master/slave card. It still doesn¹t work and now I don¹t get any output at all. I tried to follow the instructions to make the 8088 card a ³master² but I think there are some inconsistencies in the instructions. For example, it says to jumper K10 for 1-2, but this grounds the output of an 'F04 inverter. That doesn¹t seem right. I¹m sort of encouraged because the M1, MREAD and MWRITE LEDs are lit, so something is working. Does anyone have the 8088 card working in master mode? If so, can you maybe send me a picture of the jumpers so I can compare it? Thanks!
