Indeed. A couple of years back I had a floppy controller problem with the
XT that runs my EPROM programmer, etc. I put the board on an extender,
and used OUT commands from cassette BASIC to write to the various ports
while I looked at signals with the LogicDart. Didn't take long to find
the failed inverter chip that was holding the 8272 permanently reset...
Did anybody ever run just BASIC from Rom, no DOS
at all.
Yes.
The PC was available without drives $1320 with 16K RAM
and "cassette BASIC" was necessary for troubleshooting when the drives
didn't work. Lets face it
the only thing
good at that time on it was the keyboard and mono-display and warranty.
Ben.
What's SO good about that display? ($300 for board, $300 for monitor)
At least they also sold the CGA, which could be used
with a "normal"
composite monitor.
And which did sort-of graphics (the MDA is strictly text-only). Of course
you can have both an MDA and a CGA card in the same machine (my PC/XT and
PC/AT machines that I _use_ are configured that way).
Warranty ?????!!!!!!!???
What for?
I didn't void my warranty for 72 hours.
How long? I don't think I've ever kept a warranty for more than a day :-)
