The salient details of this hardware are: + + 25 MHz external clock + DRAM address multiplexing provided by 68360 + 8-bit 180nsec PROM to CS0* + 4 MBytes of 60 nsec parity DRAM (1Mx36) to RAS1*/CAS1* + Console serial port on SMC1 + +The board support package has been tested with a home-built board and with an +ACE360A board produced by: + Atlas Computer Equipment + 703 Colina Lane + Santa Barbara, CA 93103 |
