Even a cursory comparison of DOS V1 with CP/M would show that it's not a clone. A bit of investigation into the history would support this conclusion. As for CP/M being reminiscent of RSX, the only similarity is in the name of the program "PIP". On the other hand, CP/M is *very* similar to RT-11; it's quite clear that Kildall had been using RT-11 shortly before he wrote CP/M and borrowed a number of ideas from that system. -- Geoff Kuenning geoff@ITcorp.com uunet!desint!geoff
