It's got some pretty obvious name. My memory is
saying something like
'APPLE PROMS', but I'd not bet on it.
Are you sure this is on the DOS 3.3 System Master? I don't remember ever
seeing that file and I'm almost positive it would have been something I
would have looked at when I was actively using my Apple and booting that
disk often.
Did it drive
the printer that could be attached to the I/O port?
Yes.... That's basically it. Not suprisinging it was a replacement for the P8 PROM
on the bit-banger
serial card. It removed some features (block up/download IIRC) to make
some space and added an ETX/ACK handshake mode. This meant that the card
could be used to interface to certain printers, including the
popular-at-the-time Qume Sprint 5 daisywheel.
So instead of hooking the printer to the I/O port you'd instead hook it to
the serial card?
BTW, I have one of the "bit-banger" serial cards installed in the Apple ][
I'm working on right now. I'm putting together a pretty cool demo for VCF
4.0. It involves two Apple ][s, two of the Apple Serial Cards, two sets
of paddles, and a null-modem cable. The only thing I'm missing from the
equation is one Apple Serial Card. I know I have one more somewhere in
the collection (buried, of course :)
