That sounds like "Flash Attack" - I saw that reviewed in an old (but
it was new at the time) Byte Magazine. I imitated the technique to
hook my first C-64 to my old 32K PET 2001-N.

I think what Mike was asking about, and please correct me if I'm
wrong, would be to have something akin to a dumb terminal sitting off
of either the RS-232/user port of a C-64 or off of an IEEE-488 serial
port on a PET (yes... they exist... I have a couple of them, made by
"TNW", IIRC).
I'm curious about this, too. Obviously direct screen access wouldn't
work, and there might be an issue with ASCII vs PETSCII, but the
question is, I think, can you just redirect both input and output
streams to an external device, even if that device might have to run a
custom communications client to handle wierd PETisms?

Yes, that's what I'm talking about. What I have in mind is having my
various systems, which are in the basement, remotely controllable
(including power on/off) from a "terminal" in my office upstairs and,
through a bridge, via the internet for direct file transfer.
This is of course trivial for PCs and CP/M/UNIX type systems with
RS-232 consoles, and not much more complicated for systems that at
least have an RS-232 port and I/O vectors that can easily be redirected,
but the PETs are a bit of an extra challenge. Using an emulator is
probably the way to go with them (especially the graphics-intensive
C-64 etc.) but I was just curious if it had been done without much
extra hardware etc. I did think of using an old laptop to drive the
keyboard I/P through the parallel port and using CMD to capture
O/P on the serial or a second parallel, and maybe I will still play
with that a bit.
My IEEE<>RS232 (& Centronics) interfaces are CmC ADA's BTW.
Forgot about Flash Attack; anybody try playing over the internet?
