- 8080 Board

This was ECT's main CPU board for a long time.  Notice how few chips it takes to drive the S-100 bus with an 8080!

8080 CPU Board

The clock was crystal controlled and digitally generated for optimum system performance. 74LS244 bus drivers were utilized to provide low power with high drive capability. M WRITE was generated on the board and a switch selectable 'JUMP' on Reset circuit was provided for use in systems without a front panel. Low profile sockets are provided for all IC's.

The manual (with schematic) for this board can be obtained here.
