I assume that was 'third party'?
No, that's a real DEC front panel. They could have put that on an off-brand
chassis, but I would _guess_ not.
(The outer housing I can see looks like the slide-in ones DEC used to hold
the BA11-N/BA11-S, but I don't recall what the housing for the BA11-M's
looked like.)
For some reason the BA11-M's seem to have been going for more than the
BA11-N's. Dunno why, maybe the original LSI-11's have some sort of appeal?

Discovered a Z-World "Tiny Giant" SBC220D development board. Seems to
work; if powered on, the LED blinks. Its a Zilog Z180 board--and I can't
remember a thing about it other than playing with it a bit.
Yours for shipping (it's about 5x6") and should fit in a USPS small FRB.

While I'm at it, any interest in Neoware thin clients? I've got a few;
they're set up for CF card as hard disk, but most have 5GB microdrives
installed.
How about 3-button serial mice?
Cheers,
Chuck

PS: Apparently the 'official' DEC name for the 'ball on post' plastic brackets
is "latch molding". Not very descriptive/apt, alas.

There is a CPU board for sale on ebay, M8189, and it has the usual 3
chips CPU, MMU, FPU.? However, there are 2 extra chips and I've never
seen that before.
Anyone know what this is?

Board KDF11-B

Yes, those are _exactly_ what we're looking for. Thanks very much for
taking the time to take those!

So, Dave and I are getting to the point where we're about to start mounting up
our indicator panels, but we're not sure what some of the mechanical details
(below) are.
Could someone who has one please take a look and let us know (or, even better,
send us photos)?
It appears that the bezel and inlay mount to the rack with the same kind of
'ball on post' (BoP) mounting things used for blank panels.
What we can't quite make out is how the Belenex light shield, and the circuit
board with the bulbs on it, mount to the rack. I suspect it's totally
independent from the mounting of the BoP mounting devices for the bezel/inlay,
but....
The one mechanical drawing we have (RF11 engineering drawings, pg. 186) does
have cross-sections, which confirm the board is mounted to the Benelex on
stand-offs, and that the Benelex is somehow thrust up into the bezel, but
exactly how the Benelex is mounted is not clear to me. The mention of a "Mtg
Bkt Benelex" suggests that's mounted to the rack with brackets, but...
Help!? Thanks (hopefully :-)!

Hi all --
I'm attempting to resurrect a MicroVAX I (because it's there, that's why)
and the CPU appears to have developed a fault. Microverify passes at
powerup, but I can't get VMS to boot (it dies with a SYSBOOT-F-Unexpected
Machine Check almost immediately). Also tried Ultrix and it dies shortly
after enumerating disks. I know the memory and disk controllers are fine,
and there's nothing else in the system at the moment, so unless anyone has
any bright ideas, I think I'm going to need to debug the CPU.
I'm trying to track down the diagnostics for this machine, no luck so far.
Anyone have a copy sitting around somewhere? I believe there were two RX50
floppies for this purpose, DEC part numbers BL-T856A-DE and BL-T857A-DE.
Thanks as always,
Josh
