I have an HP IIISi printer. It was working fine. Then it sat idle for
quite a while (some small number of years, I think); then it was moved
(the movers picked it, and a bunch of other stuff, up and held it for a
few months before bringing it to the new place).
Now, the printer doesn't work. I turn it on and the front panel does a
brief lamp-test (each lamp in turn turns on briefly), the display says
"05 SELF TEST", then "SWITCHING TO PS", then "55 SERVICE" with the 55
flashing.
I did a little noodling around and found hints that this indicates some
kind of internal communication failure - and, indeed, I don't hear the
brief motor-and-solenoid noises that (admittedly hazy) memory says
normally accompany selftest; after the clunk of the power switch as I
turn it on, the next sound is the clunk of the power switch as I turn
it off in exasperation at seeing "55 SERVICE" again. (It's possible
there are fan noises, but there are enough fans in the room that it
would be had to tell unless they're fairly noisy fans.)
I found a PDF on www.lbrty.com which purports to be a IIISi/4Si manual,
probably a service manual from the context and the "sm" in the
filename. But every page just gives me "**** ERROR: Unable to process
JPXDecode data. Page will be missing data." and an empty page. I am
looking into other possible ways to get its content, but, in the
meantime, does anyone have anything to suggest? I'm not afraid of
voltmeters and soldering irons, but my test equipment is limited - I
don't, for example, have a 'scope or logic analyzer I can use here. I
do have a pretty good multimeter - a Fluke 87 - though.
I took the printer apart to some degree. I've had it apart before;
there was a power filtering cap that went and arced enough to eat away
some of the PC board under it. I cleaned it up and replaced it and
it's worked fine ever since...until now.
Any thoughts, anyone?

No packaging or anything, I'm afraid. They could do with a good clean, as well.
Posted because Jules just recently mentioned that he was looking for one.
I've put them up with a starting bid of a tenner. I hope that does not
seem too much like price-gouging, but I was not willing to go for my
usual 1p approach with some genuine rare (not "ebay rare") kit.
Apologies for the spam!

I have also been in touch with Kevin, but he has not sent me an update.
However, if I do get there, I am coming from the opposite direction -

It would be appreciated if you could advise me as to which items,
if any, you have arranged to pick up from Kevin so that I might
determine what may be still available.

Maybe this isn't the perfect match in context for the list, but I'm guessing its as good as any.
I've had a classic asteroids arcade cabinet since I was about 16 (1985). We ran it off and on for a few decades, and then it sat in the garage for a while. Last time I turned it on, the vector screen initially displayed only a center dot, then a line, then the full screen after a while of being on.
I wan't to bring it back up again.
What precautions or efforts should I take to get the machine back up? I don't want to damage it. The only repair made so far was a replacement of the lit player 2 button.

Hi, folks,
I did some preliminary googling and didn't find any obvious hits for
this terminal. It has a metal shell, blue textured paint, a couple of
switches on the back for features, a DB25, and the older type of
modular power plug often seen on instruments - the short recessed oval
with 3 pins.
I plan to dust it off, check for loose things, then examine the PSU
before even thinking of powering it on.
If I had to guess, and I do, I'd expect it to be a glass TTY no
smarter, and probably a lot dumber than an ADM3. Anyone have any
facts about it? I'll know more when I get a chance to open it and
clean it, but I thought I'd ask.
Thanks!

Good news, It now looks like our new 80286 Master/Slave S100 bus CPU board
works fine with not only our 4MG Static RAM board bit also the 1M RAM/ROM
board.
The problem I outlined below was due to the fact that I had jumpers wrong on
both the CPU and ROM/RAM boards. The 80286 works fine with both boards at
11MHz (with no wait states).
One of the reasons for "upgrading" the ROM/RAM board was to simplify the
"rats nest" of jumpers on the earlier boards for the diverse range of RAM &
RAM chips (including flash RAM) that board can use. The new RAM/ROM boards
should be here soon. If you have the older board, consider switching over
(it uses all the same chips/parts) . For new users it is a very useful
memory board.
One remaining bug I see with the 80286 board is that some older S100 Static
RAM boards (particularly those that use PALs, such as the Godbout 128K
static "RAM21" board or the BG Computers 256K Static RAM board), need a
patch. You need to bend out pin 2 of U56 and jumper it to pin 9 of U68 - the
bus controller. This seems to provide the early MWRITE status signal these
boards require. Interestingly this is also the case for our 8088 CPU board
(jumper K5,2-3), but not the 8086 board.
I have written up a detailed account for the 80286 boards construction
here:-

Hi everybody. I have just written up construction notes on this 80286 CPU
board.
Please see here:- for details:-
http://www.s100computers.com/My%20System%20Pages/80286%20Board/80286%20CPU%2
0Board.htm
Unfortunately there are some strange issues with the board running with RAM
boards other than our 4MG Static RAM board
(described here:-)
http://www.s100computers.com/My%20System%20Pages/RAM%20Board/4MG%20RAM%20Boa
rd.htm
With that RAM board, the 80286 is rock solid at 11MHz (no I/O or ROM wait
states required).
Please see the bottom of the page for details.
I am traveling all of next week but will explore further when I get back.
Sorry about the bad news
John
I have a cable which I *believe* is for a HP 95. It has a DE-9 female
connector on one end and some proprietary looking connector on the other
side, which seems to have 4 pins and is also female. If anyone wants a photo
I can arrange to take one and send it to you.
If anyone wants it they can have it for free as long as they pay the cost of
shipping.
I am in Manchester (UK).
Regards
Rob
