Lomas Data Products  -   Hazitall  Board

This board had two serial ports, two parallel ports a clock/calendar circuitry, 9511 or 9512 math support function (optional), and a hard disk controller interface.  That's all I have so far. Need a manual. If you would like to share one please let me know. 

The clock/calendar chop had battery backup. Software was provide for the clock for MSDOS (none for CPM-86).  The hadt disk interface was for a Western Digital WD1000 type drive.
