Solid State Music - CB2  Z80 CPU Board
This was SSM second CPU board.

 CB2 Z80 Board   

The board could run at 2 or 4MHz. The board could accept two 2716, 2732's EPORMS  and /or 4016's 2K RAM's with independent addressing to each socket.. There was power on jump to the EPROM.  The board came out before the IEEE-696 standard but was designed to be completely compatible with it.  There is a great discussion about some of the key bus signals in the manual.  Great care for example was taken to get Clock 1 & Clock 2 compatible with older boards.
