Sorry to spam the list, but I find myself in need of some holiday cash (or
positive PayPal balance, anyway) so I am offering a REPLICA Cromemco Cyclops
Camera for sale. This is ONLY THE CAMERA. You will need to have your own
Cyclops interface board set or build an XYZ scope interface as in the
manual:
https://www.autometer.de/unix4fun/z80pack/ftp/cromemco/Cromemco%2088%20ACC%2
0Manual.pdf
This will be the camera I demonstrated at 2018 VCF East. All three circuit
boards are clearly labeled REPLICA in the copper layer. Details of the
construction and other photographs are on my web page:
http://wsudbrink.dyndns.org:8080/cyclops/index.html#Cromemco
I would much rather sell it here to someone who clearly understands what
they are getting, rather than dealing with ebay. I will also include a pair
of REPLICA side panels (made from measurements of an original) that I had
made last year. I would be happy to zoom with the buyer and demonstrate the
camera in operation.
Email me directly if interested.
Thanks,
Bill S.

Hello,
I have looked at vintage UK computers on Facebook Marketplace and the
like. The people usually will not post, especially to me in the USA. They
are normally looking for local collection. Anyone in the UK want to be a
vintage computer swap friend? Looking to get some systems from there and
could help get systems from here in return. I am in the USA.
Private message if interested!

[consumables BNIB]
[operable but streaky when last in service ~2015]
Lot C : Samsung CLP680 A4 Color Laser Enet 230V
- contains consumables, level unknown
- motion fault when last used "A1-4112"
+ CLT-K506L Black toner
[consumable BNIB]
[defective "A1-4112" when last in service ~2022]
While these are on the margins of classic, I'm happy to give the community first refusal on a free to a good home basis.
Collection needs to be no later than next Thursday 8 December. If firm collection arrangements have not been made by CoP Sunday they will be offered on Gumtree ... If they are still here after Thursday, they may go wheee. Apologies for the short notice.
Replies to ftagh(a)janefield.net will be regarded as offers. Collection offers will be considered in the round, but the early bird is likely to have an advantage, accepted offers will be honoured until the agreed collection time passes, thereafter the acceptance will lapse and they will be back in play.

Found an ad from 1984 - poor resolution but gives you an idea of what the strap looked like. -W

Does anyone have a Philips P2000C CP/M luggable with the carrying strap?
I will be restoring such a machine in the near-ish future and mine is lacking the strap. Clear photos of the end fittings that slot into the machine, the dimensions of them, etc would be a great help in making something up.

Greetings,
Been a while since i have posted here. I have several PDP11 systems and
peripherals. I picked the original lot of a system 34 and related tech
in Miami FL a couple years back, and have since found several more pdp
11/34 machines, and a pdp 11/05, 11/85, and others.
It has been a goal to get the original PDP 11/34 system up and running,
however my job schedule kept getting in the way of my repair efforts,
making it easy to loose track of where i was at with the repair
progress. Thankfully i no longer work in a datacenter in a 10 hour
overnight shift, so it should be much easier to devote my time to this
repair.
I am looking for advice to get the 11/34 system up and running. I have
started to put together a site to document my progress, to stay on track
with the repair effort. The system has 2 rl02 drives, and an attached 9
track tape drive. I had worked to repair a power supply issue at first,
there was a problem with the main transformer, as well as one of the
smaller voltage "bricks". Thankfully i have many systems and i was just
able to swap in the needed working parts.
So this is about as far as I got, I had a minimal config of the 11/34
machine running, with not much more than the cpu, and a serial card to
talk to attached terminal. Power supply works, and i was able to toggle
in programs from the front panel to output characters to the attached
terminal.
I believe the next logical step was to try and attach the rl02
controllers, and see if the disk packs still have working installs of
RSX installed. I am not sure how to proceed with this though.
I have mainly been following the advice of Paul Anderson, who has been a
godsend in regard to advice and guidance with getting these old systems
fixed up. I hope that if i keep a log of the repair effort on my site,
it will allow me to pick up where i leave off with the repair much more
easily.
So that is the present condition of the machine. Good power supply, can
toggle in simple programs to print to the attached terminal. Any advice
on how to proceed is much appreciated. I Need to get an itemized list
of what hardware and cards i have on hand, and post that here so its
understood what i have.
Thanks,
Devin D.

The H7842 PSU in my Rainbow failed yesterday. At first the machine just
powered down and there was a slight burning smell, I wasn't next to the
machine when this happened, so I didn't see or hear anything to tell me
where the problem might be. Not being sure if there was a short in the
machine or a problem in the PSU, I disconnected the fans, FDD and HDD and,
probably foolishly, I applied power again to see if the machine would work.
At this point there was a bang and a flash in the PSU.
On opening up the H7842 power supply I found that one of the transistors had
completely disintegrated. It looks to be the main switching transistor, here
is a picture of it:
https://rjarratt.files.wordpress.com/2022/11/img_20221120_165850.jpg. I
have identified a source for this transistor, but if anyone can suggest a
modern replacement that would be useful too. However, that is not my main
problem.
Given that before the transistor blew up there had clearly been another
failure somewhere else, I tried to find the original failure. There were no
obviously damaged parts, so I just probed around near the transistor for any
parts that were open circuit or short circuit. I found a diode connected to
the base of the transistor that appeared to be short circuit. So, I decided
to lift one end to check it. As I de-soldered one of the leads, the diode
broke in two. So clearly the diode was either damaged by the failure of the
transistor, or it was the cause of the failure. This is the diode:
https://rjarratt.files.wordpress.com/2022/11/img_20221120_165913.jpg.
I can't quite make out the markings on the diode to know what to replace it
with. I think it says "D610". Would that be the right designation? If so,
can anyone suggest a suitable replacement please?
The diode seems to connect an inductor to the base of the switching
transistor and the collector of the transistor is connected to a
transformer. Should I be looking for other failed parts? Not sure if the
diode failed first and then caused the transistor to fail? Or if something
else has failed which caused these parts to fail?
I do know that there are no shorts in the Rainbow itself, because I have a
spare PSU that still works fine in the same machine.
I blogged this here (it repeats most of that I have said above):
