Here's the MITS serial interface everyone wants, and this one is fully tested and working! I had to replace the baud rate generator (DOA, replaced with a milspec Harris DI-4702-9) and a 1488. Previous owner had lifted two pads in the baud rate jumper area. I installed wire wrap pins so that a) pads won't get lifted when you need to change baud rates and b) you can jumper both ports to the same baud rate. Includes two nice ceramic Motorola 6850 ACIAs, original to the board. Currently jumpered for standard MITS port addressing (0x10 or 020 octal), RS-232 serial, and 9600/2400 bps.
