Which one - 'computermuseum.org.uk'? Many of the pictures I saw online were
on pages with copyright notices. I was actually hoping someone who _has_ one
the the things I listed would take a picture and send it to me.

They are in low-light locations; without flash it's a long exposure and I get
blurring because my hand isn't steady enough. And I don't feel like moving
them, or re-doing the lighting - too many higher priority things to do.

I've seen some go by on eBait, so I have an idea of the value, but I
couldn't get enthusiastic about listing them.

Again, not enthusiastic enough to put in the work...

OK, I will add that.

It's spotty, and seems to die out later on. The -11/40 boards have it, but
for the -11/45 and -11/70, some do, and some don't. None of the KDF11 or
KDJ11 QBUS CPU boards do.

Ooops. Fixed. Thanks.

That's the KDJ11-B, no? That's there.

    > Is a /44 really worth that much now?!?!  

Hey, one just went for more than that: eBait #183624991924, $3K! Admittedly,
that one was loaded, but the page does say "a number of factors will cause
them to vary considerably from the numbers given here ... Exactly which
peripherals and memory are included".

But I did adjust the number a bit - the boards are going for about $50 each,
and add in a BA11-A, it's probably $700 for a bare machine. Actually, I
really need to check all the numbers.

But I think I'd rather get the QBUS boxes sorted out first; I pretty much
only know the BA11's. If someone could tell me what later boxes to list,
above the BA23, (which I also need an image of), that would be very helpful.
