#171421 - production testing
Responding to: ???'s previous message

I can't imagine how one would "read" the program store content, as not one of my programmers has any entry or algorithm for the i802x parts, since they were not field-programmable, but were offered with masked-rom only.

There must have been some way to perform production testing, i.e. to test the ROM.
As I said above, I was lucky reading out several makes of 8042. I don't remember whether the Elnec programmer I used did have a "generic" 8042 option, or I used some of the 8742's algorithm, though.
