Thanks to everyone who responded!
I decided, after a look at the manuals, and on eBay, to go with the
23B/Unipak2B combo; it seems like it is likely to cover most things
I want to do, and was available, something I could hook up to, etc, etc.
A few points:

I checked, and the 29B/Unipak2B combo does not support them. Does anyone
know if DEC used 1702s in anything PDP-11?
Are there any other early PROMs I'm likely to run in PDP-11's that are also
going to be difficult to deal with?

Well, I don't know about for PDP-11s, but the very first thing I'm going to do
with it is blow EPROMs for a diagnostic ROM pack for my Tek 1240's, and those
take 68764/68766's (or equivalent). So that one was out, for me. (BTW, what's
the difference between the two? Looking at the data sheets very quickly, they
seemed to be pretty much the same?)

I have no idea what PROMs I will, over time, want to blow. I know of a couple
of applications right off the bat (BDV11s, which I guess take a large range
of things), and the afore-mentioned Tek 1240 ROM pack, but in the long run, I
don't really know what I'll want to do with it. That's why I said I was
looking for something that could do a wide range of early stuff.

Hi all,
I'm currently searching around for a small cardcage+backplane, if I'm not
mistaken DEC part numbers H9281-BA or H9281-BB for a bigger one. The -BA
(4x dual heights) has my preference as I'm looking to build a very nice,
cute and not that power hungry PDP-11.
Does anyone have one available?
With kind regards,

I'm working on one of these systems, and have run across a floppy
controller issue. Everything else in the system is functioning fine,
including booting from HDD. However, I have a problem where the floppy
drive has power, physically works, and connected properly etc, but what
I find is the drive/controller will recognize a disk is put in, click,
then nothing. Just due to the way I'm working on this, I haven't been
able to test any signals at the controller IC (WD2797), but I have
completely swapped the IC with a different one just to check.
Now, the question is, without looking at signals, what is the
probability the lack of any action is could be a problem with the input
to the IC (write, ready, track0, index, write protect, density signals)
or with the output signals (step, direction, DRQ IRQ)? There are
tri-state buffers (74LS244-input side, 74LS240-output side) on these
signals, and I'm thinking one of these are misbehaving, but trying to
determine which. Or could it be something completely different? Or any
good suggestions on troubleshooting this?
Hi all,
Now that RS is going down is there any effort to preserve the
information that is on their website, which I assume will go down at
some point (I could be wrong though)? Apologies if this has been
discussed before.
Things like this for example (pinouts, specs, drivers etc)

In the absence of other suggestions so far:
Brief background: Real VAXes had real diagnostics. MicroVAXes had diagnostics in ROM, or if that wasn't sufficient, the MicroVAX Diagnostic Monitor was available. Readers of the list may know where to get hold of a copy of the MDM; a quick search doesn't find an obvious source.
Moving on: Are you aware of
EK-O19AE-SG-005_MicroVAX_Troubleshooting_and_Diagnostics_May89.pdf
or similar? Bitsavers is where I found it, e.g.
http://bitsavers.trailing-edge.com/pdf/dec/vax/3800/EK-O19AE-SG-005_MicroVA…
Does your emulator have a console ROM like the real thing? Does it have any tests in it? The KA630 ROM diags are covered briefly in Chapter 5 of the KA630 Users Guide, e.g. at
http://www.vaxination.ca/vms/microvax/EK-KA630-UG-001_FEB86.PDF
A VAX is a VAX, to a large extent, so generic diagnostics (not CPU-specific) might be helpful in some cases. The detailed innards of memory management may not be one of those cases, though there are likely some CPU-independent parts too.
Have a read of the manual(s) above if you haven't done so already, see if you can get hold of a downloadable MDM image, report back?
Best of luck.
Hey all, Im looking for HP UX for my HP 9000/712
Anybody got a source, I cannot find anything and I am trying to get it
back to its original glory
Thanks

After some downtime recently due to a hard drive failure, I've received a
new ESDI drive! 30mb this time, but from a good source. Should be up again
later tonight!

I picked up a DESQA recently which seems to be configured for thinwire
rather than AUI. There is no external switch for it and I can't find a
manual to tell me how to swap it to AUI.
Does anyone have a scan of the manual? BitSavers doesn't have it, and the
Manx link is broken and is probably only for the ToC.
Regards
Rob
Hello,
I have the following manuals, I could scan them if not already available
somewhere.
Al, please could you check if you have all of them on bitsavers, or if
you need some parts to be rescanned?
