   They did have COBOL for the PDPs, but the PDP-8 and PDP-11 were quite   
   different from one another. 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).   
      
   Jeff.
