Jay,
I was trying to locate the name of the owner/founder of Western Digital
and came across your note re System Industries disk controller and
Western Dynex drive. I was the VP of Engineering at System Industries
from 1973 to 1979. The 3040 and 3051 were disk
controllers we developed
during that time. As I recall the 3051 was a 3040 with ECC
added -
could be wrong. I am still in touch with some of the engineers from
those days who may be able to answer specific question. Let me know.
