As far as I know it was not. My first exposure to the Acorn
machines were those brought over in '87 for Apple's first
attempt at a RISC Apple II (Moebius).
I never saw a RISCOS machine sold here.
I've found a few of them on eBay for CHM. Shipping from the
UK is painful. I've also had an unusually high percentage of
them never arrive.

on my bench I have a several multimeters [digital and analog], scope,

So, I've been trying for a few days to get my VAX 7000/640 (currently
with only one processor, so a 610 I guess) to MOP boot into a VMS
cluster.
I'm running OpenVMS hosted off SIMH, and have tried both 7.2 and 7.3,
and have successfully booted my VAX 4000/100 off the setup. I've also
successfully booted the firmware update utility (LFU) and the
file "ISL_LVAX_073.SYS" that comes on the install CD, through MOP.
However, when I try to do a mop boot, the system just halts and says
boot failure:

Ah, you're talking more modern pioneers, ones of the microprocessor era.
Yes indeed. Alan Sugar's probably free now :-) Just kidding. Do we have
any contacts or ideas on how to contact them? Isn't it Sir Clive now by
the way, we don't want to put anyone's nose out of joint from the first

I got the impression that the bulk of the UK classic computing community
was around the Midlands and north, with a few exceptions.
Can we have a quick poll to see who lives where? I'm about half-way up
Scotland on the left-hand side.

I'm just trying to figure out the jumper settings
on a ST-412 drive. I've read the manual and it sort
of helps, but its somewhat obtuse in style.
I have two drives which are taken from working
PDP 11/23's - they both have the same setting on
the jumper block.
The jumper block is a 16 pin DIL socket, with a
14 pin DIL plug inserted. The plug has 7 metal
bars, 3 of which are open circuit, the rest
are closed.
Working from the connector end of the PCB, the
first bar - open
second bar - open
third bar - closed
fourth bar - open
fifth bar - closed
sixth bar - closed
seventh bar - closed
Looking in the manual the first bar would persumably
be written as 8-9, the second as 7-10 etc?
Anyway, I'm trying to use this in a PERQ just to
test the EIO is working, and I can boot of floppy.
So I need to set this as drive 1. What bars would I
need to open and close?
Thanks
Ian.

That was a standard practice back in the 1960's. I still have paper
listings of a FORTRAN program to cross assemble CDC 160-A code on a 3300.
And I think (been a few years) that I have the same cross assemblers for the
1604 and 924 machines.
Later, there were 6600 FORTRAN cross assemblers for all the 3000 machines.
My copies of these are on a 7 track tape which now resembles a solid disk of
celluloid, sadly. The card decks went into the dumpster on the last move.
But you are correct about 8 bit support using FORTRAN. I know I had paper
listings for the 6502, 8080 and Z80 processors. And I think I still have
the BASIC cross assembler for the 6502.
Thinking about it, I also gave Al a paper tape for a 6502 assembler that I
used on an Apple II with a teletype. I'll have to ask Al if he has had any
luck archiving it.
There were definitely FORTRAN cross assemblers for the Motorola chips (6800
&6809) floating around for years. But I don't think I ever saved any. Must
look and see.

Great comment!!! And as to what's in a name, try "recognition" since VCF has
been going on for some 10 years. I would expect both Sellam and Hans to be

There is magic in building it yourself however it's constructed be it emulator
or hardware. The magic is that you have to understand it to build it. Simply
assembling "it" does not provide it beyond the mechanical accomplishment
though if you study the result there will be knowledge gained.

MY $0.02, great teaching tool, good for understanding hardware, excellent for
a look at a straightforward OS example that is very usable. For an old hand
PDP8/11, NS*DOS and CP/M style OSs CUBIX OS was a real eye opener to different
ways files can be orgainized.

Therein lies the greatest value. Even if you didn't build it there is a wealth
of information that applies to any CPU/system.

Having built one and meaning to spend more time with it it's a good project
and in some respects less painful than doing a Z80 CP/M machine from the
ground up. The key thing is that when operational like CP/M systems there
is enough software to be useful. This is unlike the microKIM, CosmacELF
style minimal systems where hand entered programs of a a few hundred bytes
are it.
The other feature is there is a CUBIX SIM and while building you can become
familiar, read docs, look inside the code and develop software or other
projects.

Perhaps a small group of interested parties could meet to see if such an

Not much. Just enough to have a table for my laptop & opened up Amiga. I
could bring a few issues of 80 Microcomputing aswell, which would be the
ones I have duplicates of. The duplicates aren't in particularly good
condition so it doesn't matter too much if they were to get accidentally
damaged :) All the other issues of 80 Microcomputing I have are pretty
much in mint condition and I wouldn't risk bringing to the event (is
that bad? Would anyone else feel the same way?).

Hi,

Don't get me started.... ;-)
> Yes it is not assembly, but it is also much closer to the
>hardware then most of the other structured programming languages
>out there!
I've always regarded "C" as more of a "high level macro assembler", I
personally don't regard it as a high level language as such - sort of a
halfway house.
Now, if you understand how C "works" (read K&R a few times as a start) and
the intimate details of your target hardware then you can do a passable job.
The problem is, most programmers nowadays simply don't have that level of
knowledge, which inevitably leads to large, slow, buggy firmware which is
nigh on impossible to fully debug.
And then there's the issue of readibility. I don't care what anyone says, I
find assembly language listings VASTLY easier to understand than someone
elses' "C" code no matter how well commented/documented (even when I've
never encountered that particular processor before).
I'll give you a personal example. I was once tasked with converting a real
time OS from Z8 assembly language (yes, Z8) to V50 (x86) assembly language;
we're talking a lot of code here, the assembled code filled almost an entire
32K EPROM.
Took me about three and a half weeks, at the end of which I had a well
structured, fully documented and FULLY DEBUGGED (I took a LOT of pride in
never releasing code which was less than 100%) product which was cleared for
production.
Unknown to me at the time, initially at least, my boss also tasked our "C"
programmer to do the same job. He did the conversion in about two
weeks....and then spent the next TWO MONTHS trying (and failing) to track
down the bugs in his code, about a third of which were caused by compiler
bugs rather than something he'd done wrong.
I was eventually brought in to help him, at which point I learnt rather a
lot about how bloated and inefficient the output from "C" compilers can be.
Needless to say, it was impossible for us to fully debug his code (or fit it
into a 32K EPROM for that matter) and so it was dropped in favour of mine.
"C" certainly has it's uses (I'm sure), but in my opinion, embedded
systems/device drivers isn't one of them....

Unlikely. 'B' was a BCPL derivative which predated 'C' at Bell Labs.
BCPL was used at PARC as the basic high level language for the Alto.
During this same time period, a strongly typed language called Mesa
was developed, which was used on the Alto, and later on the machines
which evolved into the Xerox Star. Variations of Mesa were the primary
Xerox development languages up through Globalview, which caused Xerox
huge problems with hiring programmers, since no one outside of this
world had any experience with the language. They eventually developed
a Mesa to C translator called Memosa.

Hi Tony,
I did try some other drives, namely some MFM drives
I had to hand from a PDP 11. These were ST-412
drives.
I simply connected the existing PERQ controller to the
new drive, hoping the hard disk would show ready, but
no joy.
The drive didnt even show a flicker on the LED.
The drives were all known working, and boot fine on a
11/23. I didnt change any jumpers as the drives were
the only drive in the PDP 11's.
Could this mean a fault EIO card?
I've examined the board carefully under a maginfier
for
track breaks, dry joints, and damage. The edge
connectors
were cleaned and all IC's have been carefully
re-seated.

Hi Tony,
Thanks for the reply.
The drive is a Micropolis 1303, and I think it has
failed. The
drive does spin down after a minute or so.
I noticed the PERQ manuals do state that the hard disk
must
be able to perform a "locate disk heads" operation,
even
for a floppy boot - which I assume means find track 0.
Hence
I'm unable to boot from floppy.
I will check the signal levels just to be sure.
Wondering where to go from here. I'm guessing I could
buy a
replacement 1303 drive - but they are not cheap (hence
my
other posting) just to try and see.
Ian.

Are there still copies of Z or the operating systems around that you know of?
I asked Dave Cheriton about this a few years ago, and he didn't have a copy.
On the chance that someone might know someone from HP Colorado Springs..
Is there any documenation around on the operating systems or internal

the hardware or software actually works.

Hi,

a Multibus backplane and eight plug-in cards. I need to be able to work on
these cards with them still attached to the bus - hence the need for an
extender.
Any pointers would be much appreciated. I'm in the UK, but am happy to
import.
Cheers,
Steve L.
