Hello. My name's Dave, and I'm a Calcoholic.

I know I am slowly sliding into another thread here... I'll stop now

That's what i was afraid off, PEEK as it is in the 71B OS, won't PEEK as the EPROM is seen as a protected ROM. [ERR:File Protect]

SYSEDIT from the JPC E2 was my friend.

Read it back and every bit should be a '1' if it is erased correctly.
