Wikipedia has corrected the “Write-Only Memory (Joke), the world is right again.
I received a ton of comments that will take a while to read and sort and answer. I see some of you have found the EIMAC data sheet. I’ll be anxious to see again..
Have patience and thanks much for the contributions, I’m overwhelmed.
P.S. Read the data sheet for the UMAC 606, sister product to the 1Z2Z I referenced. You will see the similar, sometimes exact, humor. Still need 1Z2Z data sheet.
