Probably the lowest effort option also makes the fewest changes to the
original: A small external "boost" autotransformer to give maybe 10 or 15%
extra headroom.
This could be done without using a big transformer. What you do is use
a say 20VAC 3A transformer secondary in series with the primary, wired
to that you end up with 140VAC with 120VAC in. This can use a physically
much smaller transformer than a 140VAC 3A isolation transformer.
I'm guessing the AC current at the input to the power supply is circa a
very few amps or so (why I suggest a 20VAC 3A unit above).

This week is the end of bidding on the straight 8 (PDP-8) at www.pdp12.org
I have just (Monday night) added a whole bunch of new stuff to the bottom
of the webpage, including filler panels, connector / cable assemblies, a
DF-32 for parts, some magnetic media, and a ton of docs.
Cheers,

I tried to attach a LaserJet III to a JetDirect EX Plus. The printer
looks like it's ok. It can print a test page from the control panel
just fine. I haven't tried to attach it to a computer parallel port
yet, so I haven't ruled out the parallel port on the printer and cable
yet.
I installed the HP TCP/IP driver for vista. It finds the JetDirect box
just fine. I can see in the router logs that the JetDirect asks for
and receives an IP Address. Vista lets me create a printer using the
TCP/IP "port". When I go to print a test page, nothing happens. It
just says "error" in the printer window. I can see the network light
flashing on the JetDirect. But nothing happens.
Can anyone suggest something else to try?

I blew one of the biggest deals of my life a while back. A barely used *color* NCR PC4i. And free to boot. It had a horrible death.
Well I do have a few green screened PC4s. Would like to swap out the monitor section. Came across a Samsung EGA monitor. The PC4i had 400 lines of resolution, the EGA 350. I've been told in some circles it was common to display that sort of video on something *close*. Are there inherent dangers (x-rays, etc.)? Do you abnormally shorten the lifespan of the monitor by doing that?
Available : 2 RA-60 drives.
They should be working, as they were spares, and I can add 3
RA60 packs per drive.
Pickup only, no shipping as they are quite heavy (50 - 60 Kg's).
Contact me off list.
BTW, they are in the Netherlands.

I have a published book that tells you how to mount a Mac 128k or 512k Logic Board in a PC case, and make the adapter for the video to work with a Samsung MGA Display.
It looks very similar to this unit.
I always intended to make one, but never got round to it.

On review the design isn't so outlandish since it was basically based on a

I'm not sure if I mentioned it here but I have some photos from the
office building that I was talking about 2 wks ago. There's more rooms
of this, some are mostly 70's stuff, there's 4 floors of stuff here -
all jam packed. But the other problem is getting a bigger flashlight as
there's no electric in the building. They only have one floor being
lighted at a time with a generator as they clean it out.. It's slow
going as they only spend 1 or 2 times a week to cleanup the place. But I
can reserve any TV's if they know someone is going to pick them up. My
buddy's shop is running out of space, so there's little chance of
storing any more TV's for a future pickup/delivery. This place is
located in Pittsburgh,PA. I plan to get some more photos next wknd of
any interesting TV's.
