Bob,
Thanks, that looks just about perfect. Solid state, true sinusoid 3 phase, 30A
continuous but can do 140A for 4 seconds - seems made to power a big bunch of
vacuum column tapes.

I use a solid state one, an older version of this:

I also have a small Phoenix rotary phase converter, also from ebay. This
one seems to have unbalanced outputs.

Chuck,
Is this still available? Any idea as to weight? Also how much did batteries
usually run you? I am considering using it as the main PSU for a bunch of my
vintage systems (PS/2s and 386/486 class machines). But may just be cheaper to
buy a bunch of smaller ones locally...b

One of my *US* parts supplier apparently has qty 500 in stock for the IM6100s!
With the failure rate I've been seeing, figure at least 350 of them are viable,
maybe more. I've also had a bunch come ou

Finished building a prototype mezzanine board and testing with the IM6100
(PDP-8 on a chip) in the 560Z board today. Full writeup:

There are a couple of tweaks required, but I should be doing a first production
run of boards before
Looks great!

Let me know what you come up with for the 3 phase converter solution. I have
the exact same problem right now to provide power for my 3 3420 tapes and the

Hello,
Since there are a lot of experts here ( I guess, at least ), I would like for
an opinion / ideas / knowledge.
I've been told that the temperature sensors on Fuels are subject to get

The question is due to this... I just got a Fuel donat
