I think the decdatasystem 570 is pretty, but coloured like an ice
Hi guys,
There is now a special 11/40 adapter board for the BlinkenBone system.
With that you can plug a physical 11/40 panel to the extended SimH
running on a BeagleBone.
Surprisingly there was some demand for the 11/70 panel adapter, so
adding the '40 panel may be worth mentioning.
There

I have both (though the H960 variant needs restoration).
I actually find that the corporate blue cabinets to be easier to deal with.
One aspect is that it’s a “package” rather than multiple H960 racks. Why
is that important? Because the corporate cabinets did nice things like

Speaking of cabinet variants: if you ever run into a "Corita" cabinet, with the
abstract art on the side, be sure to hang on to it. I'm not sure how many were
built, probably not all that many.
Another variation I know of: I think it was the Vaxstation-2 that came in a
small roll-around cabine
I have completed my transcription of what I felt would be the most
salient entries and information in those entries of the PDP-11/45
DEC-O-Logs.
Curiously, there were no entries at all for the KB11-D.
The transcripts are available on my Google Drive at

Yes, but also, there was apparently rework of logic feeding the CONF console
flag and associated abort signaling. Before the
Does anyone have any DC6525 tape cartridges they would be willing
to part with? One of the Expansion boxes on my VAX has a TKZ10
but none of the older QIC tapes I have can handle the format from
this drive.

My google-fu is failing me; forgive me.
Is the Tandy DWP-220 daisy-wheel printer a rebrand/OEM of someone
else? In particular, can I find ribbons and font wheels under another
manufacturer?

While I love the original purple tones and the H960 cabinets, perhaps because
they fit with most of the other DEC gear I've collected, I think that the
commercial
blue tones and Vax style cabinets are sexy as hell too. If I had loads of space,
money and time, I would love to have all of the variet

My PDP 11/40 suddenly lost it's ability to boot RL02 disks except the XXDP
disk. I have two drives, both boot up an XXDP (I have more than one) just
fine, but any formerly-working RT-11 (v 5, 5.1, 5.3) no longer boots, it
just hangs. I have been troubleshooting, running the 11/40 XXDP tests, but
My recollection is that XXDP tries not to use Interrupts or DMA, unless
it has to.
I would check out those areas first for problems if it hangs in RT-11.

RT11-SJ is less dependent on interrupts, I think, so that might be another
thing to try.
