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?

[Teal deer: I'm looking for generic any-VAX MMU-hardware test code.]
Some of you may recall that I've mentioned, a few times, that I've got
a MicroVAX-II emulator I've been working on. I think it's most of the
way there - seems to me I'm into the last 10% of the work which takes
the second 90% of the time. :-)
But when I netboot NetBSD and start to run it diskless, I get peculiar
crashes which make me think I'm mis-emulating the MMU somehow. Basic
operation seems to work fine - cd, ls, and the like - but under
conditions the details of which I haven't pinned down yet, I get
crashes like
pid 65 (install), uid 0: exited on signal 11 (core not dumped, err = 14)
panic: pmap_protect: outside P0LR
Stopped in install at _pmap_protect+0xdf: movl $15, r8
db>
I can reproduce it relatively reliably, but it takes about five minutes
to do so. I'm trying to reduce the test case to something a bit more
manageable, but, in the meantime, I also thought it might be worth
asking after possible thorough test code. I have some test code, but
it seems to be for bigger machines - 780, 8600, and the like. I
searched for KA630 and I searched for MicroVAX (case-insensitive); the
former gave no hits and the latter only two. One MicroVAX hit was a
message in one test saying
H-Floating instructions are not part of the MicroVAX instruction set,
therefore tests 71 - 98 are not executed.
The other was in a .hlp file, describing the use of the ATTACH command:
2 MicroVax
DS> ATTACH
Device type? LESI
Device link? HUB
Device name? DAA
UDAIP? 772150
[...]
Collectively, these make me think the tests I have probably predate the
MicroVAX-II. I'll be trying to get the diagnostic supservisor
netbooted, but it doesn't look designed for netbooting, and it's not
clear to me that any of the tests are sufficiently generic to be of any
use here.
So, while I will be pursuing this on my own, I'd be interested to hear
if anyone has any test code I might be able to get my hands on that's
generic (or uV2-specific) and might indicate what's wrong in a useful
way. (Useful to a simulator author, that is; "PCRB L from U248 not
getting to U144, or U248/U144 bad" is not useful, whereas "translation
not valid fault is pushing a partially incremented PC" is useful. :-)

Hello,
I managed to repair the SCSI board of my tape unit.
In the end it was fairy simple, just one bus buffer not working as expected.
On SCSI board I have ROM 193996 rev 10,
while on control board ROM 123248 rev 30 and ROMs 123615/123616 rev 06.
Could worth to update it for better tape reading support or compatibility?
Anybody has some more recent ROM?
If anybody is interested, I can share the ROM images.

Hi Lawrence,
I am going to have to go to this year's VCFM10! It sounds Awesome!

Through the efforts of a volunteer, I've re-started uploading scans of New
Zealand Bits & Bytes, Browsing through the pages might be of interest to
some.
This one is from February 1987. Among other things there are reviews on
the Commodore PC/AT and the Apple IIGS. It also includes an article I
co-wrote on a simulation I developed for my students.
http://www.classic-computers.org.nz/bits-and-bytes/issue5.5.htm
Other issues will be uploaded when Richard (the volunteer) gets time to
scan them.

On re-reading this, to ensure that I had fully extracted the content into my
brain, I realized I didn't fully grok this. Could you expand a tiny bit on
this (and especially the push-pull reference)?
On thinking about it, I guess that what's happening is that there are two
driver transistors, each attached to the center tap and one end, but with the
polarity reversed. A positive pulse through one produces a positive pulse on
the output secondary, whereas a positive pulse through the other produces a
negative pulse on the output secondary. Or am I mis-understanding?
What I don't get is why that's better than simply attaching two opposed
transistors directly to the address lines, as one sees in the output stages
of audio amplifiers, to handle the two halves of a sine wave.

I've uploaded the issues of International Journal of Computer Forensics
and the Z-Letters I got from Chuck a while back. They're on
http://www.retroarchive.org
All scans were done at 600dpi.
I'll be getting them uploaded to the IA as well.
