BG micro ( www.bgmicro.com ) still has 765,1771,1791,1793,1795,1797,2793
and 2797 floppy disc controllers if your old machine need a new floppy
disk chip. Looking at the same page they also have some old memory chips
like 16kx1 drams and 1kx1 static ram.

I'm going to get this wrong here :-) but
isn't the LK201 used on the VT220 (and
later terminals) but the LK201 used on the
Rainbow? (I guess that the Pro 380 et al.
use the same keyboard as the Rainbow,
but I don't have any of those).
The LK201 specs are in one of the appandices
that come with the VAXstation 3200 manuals
(possibly in the separate VCB02 tech manual).
The Rainbow tech manual almost certainly
includes the LK250 spec (I have that scanned
too, but it's not available anywhere yet, I think).
If someone is looking to develop a PIC LK2xx
implementation, it would be nice to handle
both variants.

Sure -- that's why the Sinclair-based systems had the keywords printed on
the keys. Those of us who use alternate keyboards either have
screen-printed keys, a chart glued to the keyboard, or, after 20 years of
squeezing the last living cpu stroke out of these things, have simply
learned them. To me, it's still easier than typing the whole keyword.
An additional benefit is that it made the built-in syntax-checker possible.
You simply *can't* enter a syntactically incorrect line of BASIC into a
program using a ZX81.
Of course, serious ZX81 programmers use very little BASIC, same as with any
other machine. I'm NOT a proponent of BASIC on *any* platform, but ZX81
BASIC sure did get a lot of kids interested in computers.
Ever wonder why the UK leads the world in game programming? Answer: ZX81
and the Spectrum. These machines taught kids to make the most of the
hardware.
The kids I know today think they're hot tuna because they can "build web
pages." They've never heard of machine code and haven't a clue what an
assembler or compiler is.
20 years ago, the inquisitive kids said "BASIC sucks, what's the next
level?"
Know what I mean?

I've aquired a copy of each:
MVII DIAG MAINT TK50 AQ-GM5AN-DN
MV DIAG CUST TK50 AQ-GL5AP-DN
I'm going to try using dd to generate an image for duplication
tonight. If I can make a bootable duplicate from the image, and if
there are no licensing issues, I'll make the images available. Any
interest or comments?

Hmm, I regard single-key entry as a feature . . .

Does anyone have hardware docs for a DEC RC25 dual drive? I just received a
couple and was planning to install one of them in my 11/725 but the power
connectors are different. Any help would be appreciated. I am also looking
for a spare CPU set for an 11/34.
I'll be out of town until Sun so thanks in advance.
Brian.

How did I do that? Not with the boot tape, DEC has screwed that up
(not supporting their supported hardware for the boot tape, duh!)
The key to success really was SIMH. With SIMH I could install ULTRIX
on an RA90 image. Then I simply ripped the "a" partition as a binary
image (3.5 MB zipped) and moved it to the VAX 6000/VMS. The move was
greatly helped by Brian Wheeler, who gave me an uVAX-II and Isildur,
who gave me a TK50 for it. Although I found out a trick by which one
can drive the console port of the VAX6000/VMS up to 38400 bps (simply
boot the machine and VMS with NO terminal attached, not finding a
signal, it bumps up the speed to 38400 and keeps it there. This allows
moving 3.5 MB in a bit less than 30 minutes.) Then I simply copied
that image onto the disk mounted /foreign, booted the disk and
voila! First time I got it up I was so excited that I messed up the
unit numbers and accidentially killed both my VMS 7.2 system and my
new ULTRIX disk! Luckily I had a spare VMS 5.4 disk in reserve. In
a way I'm happy I blew my VMS 7.2 disk, because its DU0 and that
should become ULTRIX anyway. Now I don't need to think about backing
the VMS stuff up any more!
Folks, this feels sooooooo good. I have been muddling for almost
one year for this moment!
The next questions are, since Evi Nemeth et al. unfortunately neglect
ULTRIX in their otherwise excellent book, where do I learn about such
things as ULTRIX 4.5 kernel configuration? I need to build a custom
kernel, but when I tried it with my 4.3 BSD knowledge of how this is
done, it failed because it didn't find sources and stuff. Can someone
give me a few hints? Do I have to manually copy the .o filed of the
BINARY directory into my own kernel directory? There are a few options
in the config file that I don't understand, is that described anywhere?
Also, does anyone have experience actually building the 4.2 sources?
My next steps are:
- make custom ULTRIX 4.5 kernel
- build the ULTRIX 4.2 system from sources
- get the CI working to the MTI StingRay and the HSC90
- load a bunch of software, especially GNU stuff, gcc,
emacs, bash, less ...
- Install PostgreSQL
- try building the JDK
- get a VAX 6660 and hack support for it into ULTRIX 4.2
- load NetBSD sources and build as far as it gets and
add support for XMI, KA64A, etc.
and for the other machines, get the MFM drive for my uVAX
formatted (need to produce a diagnostics tape for that.) Start
up my VAX 11/780, turn it into a 785 and make a dual CPU
machine from it. Install the PDP-8/A rack and make it going.
Final question for today: is there a program that rips an exact
tape image from a physical tape (TK70). I have that diagnostics
tape on a TK70 but need to move it onto TK50. The TK50 drive
is not happy on the TQK70 controller (or VMS isn't happy with
it.) So, I need to make a binary image, move it to laptop,
boot uVAX-II/NetBSD and write it on TK50.
Thanks so much for all your help and advice without which I
wouldn't even have started getting the VAX 6400 ins the first
place, much less making it boot ULTRIX.

Afternoon, all! :)
I've had a Vaxstation 2000 sitting around here for a
bit, but I've just gotten around to tinkering with it.
Alas, the poor fellow seems to have an ill hard drive.
I've managed to get the case open, but... well, this
is rather embarassing... I can't quite seem to figure
out how to get the drive itself out.
I don't believe it is open at the moment, but I think
the layout inside is something like this :
____________________
----Motherboard-----
--------------------
PS | Floppy
| RD32 HD
____________________
The drive is held in by at least a screw or two on the
right-hand side - I can remove those, but it is still
held in by another seeming inaccessible screw and / or
the cabling hooked up to the back of it.
Any help or recollections anyone might be able to
provide would be very much appreciated! :)
Thanks very much!
Cheers,
Andy

I would have been in real trouble had I actually been _drinking_

Perhaps "List administrator" might side-step that issue...
