Ok, the matter is simple, I'm looking for a TU55/TC11 combo.
I may have some other PDP material in trade/swap, let's talk in that case.
If the TU55/TC11 it is only for sale, we can still talk, as I don't
expect it to be without cost.
Email me directly, no need to start another thread......

I've sent some E-mails to ericj at speakeasy.net and haven't heard a
response...
I'd like to get the Xenix to you before the Canada stuff goes to
Denmark.

I brought one of these home from Bletchley last weekend - turns out
they're quite addictive little things :-) It's a Monromatic 8N-3-213
which was marked as broken - I thought I'd see if there was anything
obviously wrong inside, plus of course I was curious as to what the
innards of such a machine looked like.
Question - does anyone have service information for these machines
(yeah, right!) or useful tips on things to check over?
So far I've found an acorn jamming up the works (!!) and lots of dirt,
but the mechanism's reasonably oily still and in good condition. Some of
the keys seem to jam occasionally or not latch - I'm hoping that's down
to dirt rather than wear (it seems to be improving the more I tap away
at things to be honest).
After checking that everything was free to turn without jamming I
applied power...
There's some earth leakage which would be useful to track down -
possibly a break-down in cable insulation? I've not worked out what the
large rotating thingy on the outside end of the motor shaft does yet
though, as this seems to be connected to an insulated plate (and throws
off quite a few sparks when running)
Can't say I've ever seen such a complicated thing. Electronic circuits
don't even come close in complexity :-) I don't think I'd be up for a
complete stripdown and rebuild; I'd never get it all back together.
ps. Is there a better place to ask than here? Not sure whether
electromechanical calculators are on topic or not!
pps. Anyone care to guess a date for this machine? I'd make a wild guess
at mid-50's but really don't know.
cheers

Hi Jules
It might be that the cover was off when the acorn got in there.

Never saw one before.
...I've passed the link/question on to Chuck Shimada.

I think I saw several of these sitting in the back room of Excess Solutions
Had no idea what they were either.
I know this is a really long shot, but does anybody have
documentation, software, a keyboard, or a mouse for a Mindset?
Or maybe information about using more common input devices?
Thanks,
Doc

Very common (both the EEs and the inblowing air :-)) Nor am I claiming
to be a great airflow expert.
What I was saying, though, doesn't really depend on whether it was
designed by somebody who had a clue about airflow or not; it was likely
checked by someone who determined that it worked "well enough" under
some set of conditions. Changing something like the direction of
airflow *without consideration of the consequences* is a bad thing.
I'm not suggesting the airflow couldn't be improved one way or
another.

A little while ago, we had a discussion about the Simon Relay Computer, and
someone was going to look into scanning the articles, did it ever happen?
I have a couple of large ex-radar control units(big box with power
transformer and around 70 relays) here that are beginning to be
converted........

Hi
This is part of the continuing story of the IMSAI's history.
Some part may never be known. My machine, although obviously
and early machine, lacks a serial number. I guess that means
it has no history.

Ok People,
I'm cleaning up the barn.
All the computers have to go. I have over 150 machines sitting there and I
need to get rid of them. I do not really have time to make a full list but
most are shown or listed on my web site.
http://auradon.com/users/sanctuary/index.html
I have a fair amount of duplicates too.
I have boxes upon boxes of docs, accessories and peripherals to go with
them. I do not want to list them on ebay as that would require a lot of
preparations and shipping would be a major pain. I've got better plan for my
summer.
What I would like to do is have a big garage sale.
I'm located in the southern subburbs of the Twin Cities (Minnesota). If any
of you is interested please respond to my email: fauradon (at) fronttiernet
(dot) net
Note: I a only getting rid of the machines that appear under these titles:
Computers, Portables, Laptops and Cartridge based computers on my website.
I will keep the PDA, Pocket Computers, Video Games, Calcultors Robots etc...
I will actually take any in trade as well.
I can arrange for any convenient weekend.
As a longtime member of this group (1997) I understand the hobby and am
ready to make reasonable deals with any of you.
Looking forward to hearing from any of you.
Thank you
Francois
