Delta Products Z80 CPU Board
This board came out around 1978. It was the only Z80
board Delta made.
The board featured two serial ports (8251's) and a 24 bit parallel port (an
8255). One M1 wait state could be added for slow memory. The board
could be jumpered to run at 2 or 4 MHz. There was room for an onboard
EPROM which had to be a 2708 or 2716. It also had to reside at F800H for the
onboard power on jump circuitry to work.
The manual and schematic for this board can be obtained
here.
