Are there any PDP11 simulators that run "right down on the iron" of a
PC?
I know there are PDP11 cards that can be put in PCs, that's not what I
am looking
for.
I have "several" MS-DOS machines with 5 1/4" floppy drives that would
probably do the job, and most versions of DOS from 1.1 on up through
6.22. I'll be down in LA this Saturday (Fullerton) and could bring a
machine, or we could meet and I could get the floppies, or ... :). Or
you could mail them up here (Santa Barbara), and I could retrieve the
text files. Let me know if you still need help with this.

Anybody know where I can find documentation for these CPUs? I have some
Z8002's that are just waiting to be wired up to a board...if only I knew
how to use them! I have the datasheet, but no good programming info.

Does anyone have the capability to read 3480 tapes? Ideally, I'm looking
for someone in the Silicon Valley area who has the capability.
Thanks!

Hi Jim
If you were doing 8002's I'd be glad to help you get
a CP/M-8000 up and running. Much of the code is written
for the segmented machine so it would need to be converted
to non-segemented for the 8001. It could still be done
but would require a lot more work and you'd need a reasonable
bank switching setup. I also don't have source for all
of it so it would require a little reverse engineering.
Those pieces that I don't have source for, I do have object
libraries so building a 8001 setup isn't as much of an issue.

Hi Glen
If you don't find someone with a key, most any
lock smith will make one for around $15 or so.
I've had two keys made for me. One was a round one
and the other was a double sided. You just need
to bring the lock to a good smith.

Hi Tom,
Have you tried hooking up a 5.25" drive to winblows and see if
it can read the files off? I'd also bet that anyone with Linux
could mount them and read them for you.
If you can't find anyone closer, I'm sure I could get the data
off (I've written my own MS-DOS compatible FAT file systems). I'm
located near Ottawa, Ontario Canada - give me a buzz off-list if
you want to persue this.
Regards,
Dave
