Does anybody, by any chance, have a copy of the processor technology "Simu-cisor" program? It is a program for testing a Persci drive that exactly simulated the Persci factory drive exerciser hardware using a PT Helios disk controller. It was distributed on audio cassette tape, not disk, and it's tape name was "SIMU". It was only a dealer/service center item, it was not normally distributed to end-users. If you have this, please contact me (Watzman(a)neo.rr.com). Thanks, Barry Watzman
