[comp.sys.cbm] Help with Cardco C?/B printer interface switch settings?

miker@shamu.WV.TEK.COM (Mike Reiney) (09/17/90)

I acquired a Cardco C?/B printer interface for the C=64 and can't
make it work.  Open 4,4:print#4,"text" does nothing (except lock up
the computer waiting for a response from the printer).  I tried all
the switch settings.  I even tried address 5.
Yes it does have power from the printer and is drawing about 270
mA.

I had a similar one before, but this one is quite different
physically.  It's a board with a sleazy moulded plastic cover that 
slides over most of the back end.

There are three configuration switches on the board.  What do they
do? (Want the truth table)

As I recall, there are several secondary addresses.  What are they
and what modes to they enable?

Thanks for your help.
