Alpha Micro -  AM-310 Four Channel Serial I/O Board

This board came out in 1982. Again quite advanced for the time when most serial boards had only 2 serial ports. It is another quite rare board. 

AMD 310 Board

The board was claimed to be S-100 compatible. (This needs to be confirmed since their AM-100 CPU was not).  It had four RS-232 I/O ports which were independently controlled by an onboard Z80 and DMA controller.  Again this board was clearly designed for an efficient multiuser serial I/O system.  

The manual for this board can be obtained here.
