Single board 68008 computer. The entire computer was all CMOS except for the processor. The idea was to have it battery powered. Onboard was 1MB dynamic RAM of which 983kB is accessible. Three '157's mux high order and low order addresses to the DRAM. The DRAM was software refreshed by a routine consisting of 256 NOP instructions. I/O consisted of a R65C51 ACIA combined with a MAX232 for RS232 level signals. The DTACK signal line on the processor was grounded as none of the chips required wait states. The processor was run at 7.16 MHz.
