This reminds me, when I was attending UIUC in 89-93, PLATO was still in
use, and someone (not sure who) had created a PLATO emulator for the
C64. It did everything, as I recall, and connected to the PLATO system
using the UIUC dialup network (333-something, but time has erased it
from memory... You could access all of the machines
from that dialup
system) It used 1200 bps as I recall, and worked well.
Sadly, I cannot find the disk with the SW any more. I wish I could, as
I think the PLATO archivers would want a copy. I don't know if other
8-bit machines had ports of the emu.
