Wait why would a PCB have EPROMs and SRAMs on the same bus with demuxes feeding the chip-select pins? Not useless, but I'd have expected it to be easier to transfer data from RAM to ROM if they were on seperate chip-select cycles. Maybe they still are, if the inputs to the demuxers are independant on the mother board, since this is just a daughter board with a header.

I really wonder what this thing came from, since it's got ~100kB of EPROM and 20kB of SRAM. Some sort of computer that uses pin headers like this for its memory board? I may see if I can get other parts from the same machine.
