Thank you!
It would have been nice to be able to disable the
PC's base memory to
allow all ECC memory but there was no easy way without hacking up the
main board.
At a West Cost Computer Show in 1982,
PC Faire?
(Fall 1982, offshoot of West Coast Computer Faire, you were in
the balcony of Cicic Auditorium?)
some IBM employees came up to my booth and pulled out
memory chips while
the board was running on an extender card. They did not believe it was
real ECC memory. After seeing it was still running, IBM bought 50
boards. That was our biggest sale.
No one else really cared about the ECC, they just
wanted more memory for
cheaper.
I cared.
Although I was/am cheap, I'm disgusted by "Macintosh doesn't have a parity
bit, and it NEVER has PARITY ERRORS".
