Hi,
Although CPN isn't real CP/M, its an
almost-compatible look-alike. A
Torch Z80 won't run real CP/M, though it will run a modest subset of
CP/M applications.
Agreed, this was the main reason I got rid of the system all those years
ago....I'd already got several Beebs at that point (and had just picked up
the "Visual 1050").
PDP-11/23 +
Z80-CP/M co-processor card
That's unusual too. Who made the Z80 card?
Again, I got rid of that particular machine quite a few years ago, I don't
recall the manufacturer of the card.
It was a standard dual-width Q-Bus card, containing the Z80, 64K DRAM and
various support chips. Communications with the board was done via a serial
port located near the module's handle, with a pinout compatible with the
ports on a DLV-11J.
That's about all I remember about it, I only ever firec up CP/M on it
once....I was more interested in the DEC side of the system. ;-)
Perhaps I should've kept the card when I got rid of the machine, but then
hindsight is a wonderful thing....
Transam Tuscan
Another unusual one. Does it work?
You would have to ask about the machines I've parted with.... :-)
It was in working order when I got rid of it, but that was a few years ago
and I'm no-longer in contact with the chap who had it from me.
I hadn't realised how rare these machines are, otherwise I might've kept
hold of it. But it's the usual story of too many machines and not enough
space/time.
