Heathkit ETA-3400 Modifications

[Paul A. Pennington]

    (Talking to myself again)

    OK.  I just got off the phone from calling Heath Educational Systems. 
The only ETA-3400 manual they sell is 95 pages long, so that must be the 
operations manual.  They want $35.00 plus $6.50 shipping for it, by the way. 
$41.50 is pretty strong, in my opinion.  Fortunately, this is the one manual 
I already have -- it's proper title is:

Heathkit Manual for the Memory and Input/Output Accessory for the ET-3400 
Trainer, Model ETA-3400, part number 595-2271, copyright date 1979, 95 
pages.

    If anyone has the manual (not sure of its exact title) describing the 
modifications necessary to connect an ETA-3400 to an ET-3400, please email 
me on or off-list.
