The connector
at the centre-front of the EI is electrically
unconnected (apart from grounds) if the serial board is not installed,
so anything that connects there will need the serial board. Period.
Ok, then I'll go back to my pathetic and desperate plea for a couple
serial boards for the TRS-80 EI.
Will trade for money, food, sex, whatever.
Wasn't there a TRS-80 modem that would connect to the EI connector on the
back of the keyboard unit?
