The PDP-8 was fairly primitive as computers go. It didn't have a consolidated CPU, the memory consisted of iron rings woven together with wire, and it had no concept of a stack. It had only 8 instructions, with one instruction including all operands per 12-bit word (with one exception). The exception was a microcoded instruction that could represent (and execute) multiple operations simultaneously. DEC's goal with the PDP-8 was to make an affordable computer (<$20K) for people and businesses who may not have needed a full-blown IBM mainframe. Although it's dwarfed by even the most modest of modern computers, it was quite popular at the time. There was even a cheaper, slower model, the PDP-8/S that had a serial system bus: it did everything one byte at a time. The PDP-10 (a successor to the PDP-6) and PDP-11 were more advanced. I can compile a DOS or Linux version if you'd like (although I'll bet that there are already Linux binaries out there somewhere).
