Hi,
I used the following entry lines and successfully copied DECtapes.
set df enable
att dt0 os8.tu56
att dt1 os8drv.tu56
att ..... (what ever other drive you use)
Then it is striaght forward: boot dt0, and access dt1.
The "tape names" (os8.tu56 and os8drv.tu56) should be substituted
by the names of the files that you use, of course :-)
I don't know much of pdp8's, there are others that know a lot more!
success,
- Henk, PA8PDP

As far as I can remember (at work now) they have the following shape,
the bracket is drawn in front of the box. The "s" is a hole in the
bracket. The flange (at both sides) at the front side of the box has
also a (bigger) hole. You put in a screw (s) from the rear side of
the flange, through the bracket and tighten the screw on the front
panel. See the figure. F=front panel, B=bracket, BA=box.
Making such a bracket from a strip of aluminium should not be too
difficult.

I'd pull the MXV11 and the National card them bump every one up.

Thats a good sign.

I don't think which is which matters as it's a parallel pass through
and the drive select plug is the determining factor.

Should list the devices the system knows of. It may be possible that
one of the cards is not passing intgrant. If the system doesnt show
the RL02 either grant chain is broken or the controller is not there.
Which controller? Two board set or later single board m8061 one?
The controller (RLV12) must be address at 17774400 (q22), 774400 (q18).
The vector is 160.

I got my PDP-11/73 booting by connecting an RX02 drive to the system
and using an RT-11 boot floppy. I've convinced myself that the 1.5mb
of memory (two M8059s and a third party card) works and that the
KDJ11-A CPU is working as well as the multi-function boot card
(M8047) and the RX02 drive and controller (M8029).
Unfortunately, I still can't access the RL01 drive. RT-11 sees the
controller card but if I type "DIR RL0:", there is no indication that
the drive is even accessed. The disk seems to spin up and the ready
light comes on on the drive but I don't seem to be able to access the
drive from RT-11. I've also tried using a scratch pack and typing
"INIT DL0:" but that doesn't work either. Does anyone have any idea
what might cause this kind of behavior? Also, can anyone make me a
bootable RX02 disk with the RL01 diagnostics on it? I can supply the
blank disk?
Thanks,
David
I discovered a couple of these (ceramic carrier, 16 pin DIP) Fujitsu
MB8907F. My databooks and an online search shows nothing. What is it?
Cheers,

Subject: Panel question
I'm trying to mount the front panel on my 11/34, but I've run into aproblem: I have no mounting brackets. What do the brackets look like formmounting to a BA11-K, and does anyone here have any extras?Secondly, was there a H964x style beige panel with black vents that would goon the non-covered portion of the 11/34a's BA11-K? I seem to rememberseeing that sort of thing on some 11/44s and 11/24s.Again, any advice would be appreciated.

I thought I had an extra, and was going to look at it. Seems like
I must have sent it off to someone. It's not like the older clip
on panel types. It is screwed to a bracket. If no one else comes
forward I'll remove the one from my 11/34 and look.
As to the other panel, mine is simply a 1/2 DEC black panel screwed
in from the front above the programmer panel.

I'm trying to mount the front panel on my 11/34, but I've run into a
problem: I have no mounting brackets. What do the brackets look like form
mounting to a BA11-K, and does anyone here have any extras?
Secondly, was there a H964x style beige panel with black vents that would go
on the non-covered portion of the 11/34a's BA11-K? I seem to remember
seeing that sort of thing on some 11/44s and 11/24s.
Again, any advice would be appreciated

Well, I was working on my 11/34 last night, and I noticed when I flipped
it on its side that the power regulator H745 does not have its red light
on. Does that mean the other two H744s are problematic, or does it mean
that the H745 is the problem, or is this all normal?
Opinions please! :)
Thanks
Julian
Hello DEC community,
How much of a market is there for sealed in box DEC RKO7K DC disk packs?
