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.
