Hi,
I cleaned the dust out of a small 4 slot card cage with the power supply
at the right side. I was never good at naming the BA box types, so here is
the description. When you look at the front side, the 4 slots are at the
left side, and the PSU is at the right side and has at the front 3 switches
(DC on/off, enable/halt, and LTC on/off) and 2 LEDs (DC on and run).
The following cards are installed (I have not yet powered up this unit).
<------ M7270 ------> <------ M8044 ------> ==================
<------ empty ------> <------ M7940 ------> | o o __ __ __ |
<------ empty ------> <------ empty ------> | ~~ ~~ ~~ |
<------ empty ------> <------ empty ------> ==================
I have 2 questions from this system.
1) As I am not that familiar with QBUS, are the cards in the correct slot?
2) The M8044 says on the handle "M8044-DK" but on the board is in the etch
"M8045" and "16KW x 18 BIT" (IIRC that last part). Strange or common ?
An other thing is the following. I also have a M7264. This board is quad
sized,
but has 4 kW memory on the CPU board. The M7270 is dual sized (with no RAM).
Can I remove the M7270 and M8044 and put the M7264 instead in the above
rack?
The reason for this swap is that I hoipe one day to add a M8018 (WCS), and
as far as I know, the WCS option does not work with the M7270, but only with
the M7264. Is this correct?
And *if* the M7264 is installed, can I then move the M7940 to the left in
the
same slot and put in the open space the M8044?
A lot of questions ... I am really into UNIBUS machines, but this small
system
is too cute to put away!
thanks,

At a garage sale recently I bought what I thought was a 'complete with
software' Commodore 64 system. When I got it home (two printers, two
disk drives, C64 system, cables, etc.) I discovered that all the
colorful printed software boxes were EMPTY. Well, some have inserts and
what-not, but there was not a SINGLE diskette with software in any of
it.
Someone obviously grabbed the disks to use for some other purpose, or
they were all in a case that was lost or thrown away.
Anyhow, I am going on the notion that there are probably Commodore
collectors who would like to get these boxes anyways. There are a
mixture of different boxes for various things, games and what-not. It
will be relatively inexpensive to ship them since it's all empty boxes.
First respondent who shows interested in these gets them for the cost of
shipping.

It's cleaning-up weekend here.
I have a medium-sized box of Apple drive sleds to give away. These are
the slide-in plastic parts under the drive, that I've salvaved over the
years. I'm not doing much anymore with 'beige box' Macintoshes but
thought maybe somebody else could put them to use. There are 3-1/2" and
5-1/4" (CDROM) sleds included, from a variety of Macs. Mostly
7200/7300/7500 desktop cases.
They're in a USPS Priority Mail shipping box right now and anybody who
wants them can have them for the cost of Priority Mail (so I don't have
to rebox them) shipping from zipcode 46131. The box weighs aprox. 8.5
pounds.
As always, first serious respondent gets them.

Toner system clogs, sticking cleaning blade, developer unit problems,
drum(photoreceptor) issues, paper handling. But the bulk issues
were print quality related.
At a bare minimum before using I'd pull the cleaning unit and developer
unit and thoughly clean both, inspect the drum for surface damage and
make sure the cleaning blade is good condition. Then I'd inspect the
corona assemblies and lamps for operation.

I got to monitor the service the performance of all 1500 sold. Most
were used at the 200,000 page per month and higher level and FS
weren't making money off them. A few machines set records at over
800,000 pages a month and FS were visiting them every two weeks
for major work. It's true it was much better than the little
ones but when that thing hit around 2 million pages it really
wanted a lot of work. At the other extreme it tended to perform
poorly if it didn't run regular and the running joke was 45days
or 150k page whichever came first. The problem being simple,
it was fast was not enough as people wanted/expected print volume
to replace Xerox9700s, the other extreme wanted only a few pages
but 11x17 printing was appealing.
The uVAX however, check the fans and keeps on truckin. A DELQA
gives better service but many had DEQNAs that works just fine.

That will help.

Being close or atleast based on Forth stack language it was fun to use the
uVAX in the laps 40 to do things like process and print calculated results.
My favorite was a print job that stayed resident and printed pages as 2up
as a paper saver. Another like that counted pages used since loading.

You may just have to. ;)

I was highly disappointed with the reliability. Anything that
could print at 40ppm was likely to see 100-250,000 page month
and that machine was good for maybe 100-150k pages between mech
failures.

You may need to do a bit to get it working if it's been sitting for
a long while. One the toner tends to pack or harden if cooked
at 110F or higher. The selenium drum may be ok, tough to find
if damaged.
The worst part is wearout parts such as feed rollers and a few
other bits. It would help you to find a few for parts.
The other part is my memory os 15years old so there may be
some I forgots. I didn't keep much in the way of docs.

Have you tried Armour All (that's what its called here) - its used for
revitalising Vinyl and other plastic type stuff

Subject: Restoring (and I do mean 'Restoring!') Plastic
Hi, gang,
Got a couple of 3M telecom test sets (965TD's) that need some
cosmetic help. No, they're not off-topic. First, they both use an
embedded DOS-based computer, and second they're both over ten years old.
Anyway... The outer housing is made of (I think) high-density
polyethylene, the same stuff that the outer jacket of telephone cables
is made from, molded in bright glossy yellow. At least it was bright and
glossy when new. As one might imagine would happen with field craft
instruments, these have been dinged and marred pretty badly.
My question is: What's the best way to restore them? I've tried
simple plastic cleaner/polish, and it helped a bit, but the scarring is
still there. What I'd like to do, ideally, is take enough of the outer
layer off to smooth things down, and then polish it up so that they look
new.
With that in mind: Anyone know a good way to recondition HDPE?
Thanks much.

I completely missed this item on eBay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5226857402
It's an Altos 586 system with all the system install diskettes.
I have an Altos 586 and would REALLY like to have diskettes to reinstall
the OS 'stock' (mine has a limited version of Xenix with an 'office
suite' on it as well). Does anybody know this buyer?
