Intel iSBC 188/48 Single Board Computer

I obtained several of these boards in 1998. I will use them to provide terminal connections in the other multibus systems I am working on. I am also looking to use one to provide cross connections and translation between baudot teletype equipment (teletypes and terminal units) and ASCII serial devices (computers and terminals) in my amateur radio station.

iSBC 188/48 Board

I have partially disassembled the EPROM with the code from this board. The source code code is found in file 147305.asm. The MASM listing is found in file 147305.lst. This software was originally written in PL/M-86. That is evident from the assembler code generated. The source code will assemble with the MASM32 tools.
