I mean, the Atlas II *does* have good heat tolerance because it's smaller! :-)
Brain fart again.

For third-party controllers, extremely common. For DEC controllers, rare;
in fact I can't think of a single one that does.

Not necessarily or even usually on a bus terminator card. On the 11/24,
11/23+ and later Qbus processors (11/73+, 11/83, //53, 11/93), the ROMs are
on the processor card. For many Unibus machines, and the Qbus processors
that didn't weren't integrated with SLU, LTC, etc, it was often on a
separate ROM card or a multifunction (SLU/LTC/RAM/ROM: MXV11-A or MXV11-B)
card. The BDV11 used in 11/03 ansd 11/23 systems was unusual in being a
combined terminator/clock/bootstrap card (like a TEV11 or REV11 with
extras).

I've seen (indeed, own) another card that does that. I think it might be
one of my Dilog cards, but it could be the GR RXV21.

This sounds like the Cornell Program Synthesizer developed
by long-time Cornell professor Tim Teitelbaum. It was used to
teach Pascal to tens of thousands of students at several large
universities in the early 80s, on Teraks and perhaps other
computers. I think he gets the credit for developing the
first practical language-sensitive editor, the progenitor
of most IDEs out there today.

How does a PDP-11 boot from an RQDX3 controller?
I have several 11/23's based on the KDF11-AA CPU, which has no on-board boot ROM. The Andromeda UDC11 disk controller that most of these use contains the boot ROM. These machines are in a 4-slot dual-wide card cage which is full. There is the CPU, a memory card, the disk controller, and a serial card.
A couple of these machines are missing the disk controller. RQDX3's seem to be readily available, and there is adequate documentation of the card on the web (jumpers, cable pinouts, etc). Will the KDF11-AA be able to boot from an RQDX3?
If not, can anyone suggest an good alternative?

Just saved these PDP11 related docs from being dumped. 1st come, 1st

Not wanting to offend anyone, just going from prior experience and my

That's okay, only 50 meg is going to be Mac OS... everything else will be
A/UX partitions for NetBSD! ;)

However...
I *think* you'll need OS 8.1 or later to format a drive
that large as a single volume. Formatted as two 2GB
partitioned, you should have no trouble using older
Mac OS's.

Dear sir
I,m write to you about a lap top computer,Taht i,ve found on a job site they where beening disgared so i kept one.
But the poeblm with it is I get a (ple wait) come up then it go to (- ) then it run a driver then stop.
I think the programs have been deleaded , i was wondering if i could get a restart programs for it could you help me the model is a Amstrad PPC640S portable personal computer . If you can help me i would be very happle.
My email adress is austn29j(a)icqmail.com
Anything to help would be good.

If he doesn't let go of it, get back to me, I think that's the
trash-80 book I pulled off a garbage pile a few years back. It
won't be in pristine condition, of course.
Just lemme know...
