I have a couple of metal tags for a Documation M200 card reader - one
the front green tag with M200 and the logo, and the other the back
(bottom?) black tag with the serial number and stuff. Both in pretty
nice shape.
All this for a buck! Postage included!
Don't be a dick and reply off list, please...

Hello Henrique,
i have same problem as you, reading BRUSYS floppy from RX33,
do you get any help according to your question?,
i would appreciate any help you can give me
thank you
Rolando Cornejo
Dear Sir,
I?m in trouble with the system as the boot stops at :
RSX-11M - Plus V4.3 BL66 2044.KW System "Pt/Ps"
> RED DU:=SY:
when loading from RD53 (RZ 28M-E)
and stops at:
RSX-11M/RSX-11M Plus Standalone Copy System V03
when loading from RX33 (Brusys floppy)
Do you have an idea why the boot does not go on?
Thanks in advance,
Henrique Gomes.
Hi,
I just recognize this situation before 1th of April, and I send
eMails, that I could take care of one or two dec systems (pdp8) but I
never get an answer back.
Hope their systems arnt scraped!!!!!!!
Yours
Gerhard
I for one would like to see it (hope you remembered to record it!). I
would see it myself, but our aerial is actually pointed to Central and
not Sandy Heath (Anglia TV) after my parents got some guy out to allow
my & my bro to have a 2nd aerial line fitted into our bedroom years ago.
We didn't realise what he had done until he had left and he never
returned any of my dads phone calls. I guess you could say he was a rogue
trader of sorts.
I couldn't be more local to Cambridge... ok, perhaps I could if I lived
*in* Cambridge and not nearby (Cottenham). I'd certainly be interested
in being involved with the museum, once I get up and running with my
car.

I'm in the process of thoroughly cleaning my MicroVax 3900 in preparation for installing it in my upstairs computer room. This will be the only "big"* machine up there, all the rest of the iron lives in my semi-finished basement computer room. (concrete floors, plenty of headroom, easy power installation...).
The problem is, that my upstairs computer room has always had a bit of a problem with heat and power. I'm installing a second 15amp circuit, but heat dissapation will be limited to the central air conditioning and ceiling fan.
So, what I'm wondering is... how much power will a MicroVax 3900, with two RA90's, draw?
And similarly, how much heat will it put out?
Thanks!

* Note how I put "big" in quotes. I know that a MicroVax 3900 is not a big machine, compared to, say, most of the other Vaxen and stuff I own. But, it's bigger than an SGI Octane, it's bigger than a Macintosh, and it's bigger than the PC's and all the other boxen that live upstairs. So, comparatively, it's "big". Ironically, however, I think it's smaller than my printer.

That's not bad at all compared to some of the stuff
I've bought over Ebay. I've been pretty disappointed
at some of the 50 or 70 pound lab instruments that look
to be in perfect pristine condition before they're shipped
to me - but arrived in way way too little packaging and
with all the corners bashed in and knobs broken off by
the time they get to me.
Usually I'm so sad about the whole destruction of what
was just a few days before a very nice example of 50-year-old
technology that I can't even bring myself to leave negative
feedback. What's the point, the seller won't learn, and history's
been lost in any event. I'm even sad that I participated in
the destruction (although I make it very very clear to the
seller what I think he ought to do in shipping, usually the seller
just takes it to the "UPS Store" and let them put it in a
lightweight carboard box with some peanuts.) I'm left not chuckling
but pretty depressed.

However the swithers used are less likely to overvolt than fry the
high voltage side (chopper fails!). In the case of the Robin that
is there the risk is (other than the video board cap).

Hey folks;
So I'm busy reading the manual to my brand-new-offa-eBay 1630G and, page
by page, I'm more and more impressed. I've never owned one before and it
just seems like pure magic. I've got it hooked up to a huffy Vector
Graphic in my basement (which diagnosed a bad Z80 in a matter of seconds
on my test try!) and boy is it useful.
First business - does anyone have swaths of the double-grip HP probe
grabbers they might be willing to part with for a reasonable sum? Just
askin' :)
I'm reading the section on the 'inverse assembler', which really is
remarkable (like I said, I'm new to this) to have it disassemble various
CPU instruction sets. What I do not have, though, is either the
appropriate disk drive set (HP 9121S or 9121D, according to the manual)
nor any of the invasm packs.
I don't suppose there's anyone out there who may be willing to also part
with either of the above, again, for reasonable recompense? With the
Vector I'm interested in Z80 invasms - but, frankly, the options seem
endless given the smattering of 8-bit processors I have covering my
shelves in need of attention.
There's a 9121D on eBay (6 days out) for $60 w/shipping, which is...
do-able but seems a shade hefty. Maybe they're getting harder to find
these days, I don't know. As for the invasm packs, for all I know they're
complete unobtanium - but I figured I'd go to the repository for such
knowledge and see what people thought.
Many, many thanks to all.
- JP
