It's fairly simple, if a bit stupid.
You can see an older version of the Datatrieve code inside the C file,
but a more up to date version is in the CMD file.
The C code also make use of a C library to access the DTR call
interface, making it a bit easier to use than the standard interface DEC
defined.
Ok, it sounds like that's a good example to learn from. I hope to
dig into it soon(ish).
An extra RL02 is almost invaluable. We do crash dumps
on it, we run
diagnostics from it, we can easily move files to/from it on the RL02 and
so on...
And the tape drive is nice for backups, software installations...
Although nowadays with virtual tapes, the tape drive isn't needed that
often. A long time since the last RSX release came around. :-)
TU81 is 1600/6250. So from time to time we have hooked up a TU77 as
well. But the status of those drives are a bit unknown today.
That reminds me, I forgot to mention, FANG does have a TE16 on an
RH70. We're waiting for Terry of Terry's Rubber Rollers to finish
recovering from covid19 so we can get the roller re-done, but we've
gotten it to the point where it pulls tape.
Yes we very much want to plumb in that RL02.
But occasionally we also get requests for media
conversions... For that
purpose we also did plan for quite a while to hook up an RK11 and RK611
to Magica. But now I think we'll have to scrap that plan.
:-(
If you get stuck and need RK07 work done, LSSM has an RK07 on a
PDP-11/50, and another on a PDP-11/t55.
I sortof don't like the 11/34 that much. Boring
front panel (if you even
have one), and limited capabilities. :-)
The 11/34 is my favorite PDP-11, because it was my first, 36 years
ago. (not this one, but one just like it)
The one other big thing on the wish list for any 11/70
would be a
PEP-70/HC-70 combo...
Yes, that would be very nice indeed.
