Z80 Computer Board

I picked this board up at the dump. Z80 CPU, Z80 SIO, Z80 PIO, Seeq DQ2817A 2k x 8 EEPROM, 6116 2k x 8 RAM, 32k EPROM, ADC0808 A/D Converter, AM26LS30/32 RS-422 line drivers. The EPROM label reads

487635003W SERIE 01
 FW-ATU-PRESET 1/1

The PCB is marked 045.763.019L ED-1 on the top and the bottom.

Interesting to note is that somebody some time fixed or tried to fix it -- notice the places where the conformal coating is burned.

I have no idea where this board would be from. No clue in the eprom dump either.
