[pups] PDP11 reverse-engineering(sort-of)

[Jacques Wagener]

Hi there !

Over december last year I had my first wonderful expierence with a
micro-pdp11 running Micro-RSX.
In actual fact I haven't tried much, only a complete reinstall of the
system(which was unecessary, because I've got backup tapes !).

But still an amazing moment.

What I wanted to ask is, in what manner would one transfer old
data/programs/source code from an old
hard-drive/tapes/floppy to more modern drives etc. I basically need to
transfer controller-programs over to x86( Everything works, I believe, but
old hardware is scares) where I want to connect a modern pdp11-interface
card.

Thanking you in advance

Hi.
Nice to hear you have a working system.
As for transfer... Well, there are several ways.

DECnet (if you have it).
KERMIT
TCP/IP (if you have it).
Tapes (if both machine have tape drives)
Disks (both could have SCSI for instance)

So it very much depends on what hardware and software you have.
Also, if you plan on using the Osprey (which the mail almost hints at), 
I think they have the option of hooking up the old disks to the Osprey 
as well.

And then of course, you can ship the disks, or tape backups to someone 
who can do the conversion for you. Me for instance. It's also a question 
of time, money and safety issues involved.

Let me know if you want more help.

Apart from the tools that Johnny mentioned, there is a program I once
write called VTServer, which copies entire disk images into hardware
over a serial interface. The program has since been taken over by Fred
van Kempen, and I don't have a canonical reference to it. However, if
you search for "VTServer fred" on Google, it should turn up.

Cheers,

Wasn't that an RT-11 thing, Warren?
(I have a short memory...)

Actually, it was based on the 2.11BSD bootstrap code, but with a
"virtual tape" device. See
http://www.tuhs.org/Archive/PDP-11/Tools/Tapes/Vtserver/vtreadme.html
for my original version.
