*** REPLACE THIS LINE WITH YOUR MESSAGE ***
I have an Apple //e with a Super Serial card and have found a way
to use a Prometheus Promodem at 1200 baud without any characters
dropping. The problem wasn't the slow firmware in the card, but
rather the way the card didn't work with my 80col card. The solution
was to use a Microsoft Premium Softcard //e (Z80 processor, 64k addit. 
memory and an 80 col card all on one huge board) as my video interface.
For reasons unknown to me, this configuration works perfectly!

	Feel free to mail me with any questions regarding dip switch
settings, cables, modem configs. or anything... I've spent two years
trying to get to this point and I might be able to help. Keep trying,
it feels great when 120cps fly across your Apple screen!
