I just _know_ there was discussion of this subject within the last
year or so, but )&(^ Google doesn't turn up anything.  I'm interested
in writing a filesystem driver to support an A2 as client on a
DriveWire server.  This is a simple protocol developed for the Tandy
CoCo, but it's generic enough to be adapted for almost any small box.

The CoCo can bit-bang serial communications at 115k baud, so I'm
hopeful that something like this is possible for some flavor of Apple
2.  There was some talk of folks achieving hi-speed serial I/O on bus
cards (Super Serial card?), but cannot find the thread.

Also, some years back Don Lancaster had some sort of bit-banging
serial driver that used the game paddle connector to talk with a laser
printer. Can't find any detail on that either, just some peripheral
mention of it on the "Ask the Guru" website.


Search google using "site:tinaja.com 57600 apple ii"

First hit for me was:

See page 110 and following.
Bingo! Give the man a prize. That was what I was looking for. Thanks very much for the pointer.
I tried at least 5 permutations of "apple 2", "game paddle", serial, "laser writer". Basically danced a complete circle around it. As I said, I'm doomed when it comes to Google. Whatever I think of for search terms is guaranteed never to find what I'm looking for :-).
