I should have a Teledisk image somewhere that I got from Don a few years back.
Email me off-list so I'll be reminded when I get back to the office in a few days.

Well that's interesting....
How much of it will be running?

Don't worry, there will be :-) Plus there'll be various other British
machines littering other sections (Inmos, ICL, Elliott, Marconi, BCL,
Digico, Diamond
etc.) which naturally fit better with some of the other 'themes'.
I'm not quite sure when the room with the focus on British machines will
come on-line; notionally we're starting at the top end of the building
(Colossus, Tunny et al, workshop, really big iron, analogue machines)
and working our way down the corridor room-by-room. The 'British Room'
is about halfway down - hopefully get to that one in around 6 months or
so. It's slow going as every room ends up having to be gutted, cleaned
and repainted...
I was going to ask about Irish machines and see that James got there
first; did Ireland ever make any micros?
We spent today doing some final assessment work on the ICL 2966
mainframe prior to its move to final destination (as well as the 40 or
so cabinets there seems to be a metric buttload of spares).
Wall-painting's now finished in the room that it'll be going in to, and
a couple of different firms are coming in on Monday to see the beast and
give us a quote for moving it. If all goes well hopefully it'll get
shifted in the next couple of weeks...
cheers

That's the first I heard about a Belgian computer. Not sure whether you'll
actually find one seen that I never came across one (and in fact, I didn't
even know we made computers at one time...)
Hi, do you still have the H716 minicomputer? I worked on them from 1970 for some 20 years woth Honeywell in the UK. Do you still need help with your wonderful machine? If you are thinking of disposing of it please let me know.

Before I write to the group, Kurt Klemm, if you read this please try
sending me a message on my web forum at http://www.stockly.com I am
getting your e-mails but based on them it sounds like you are not
getting mine! : (
--- Now to the rest:
I'm wishing I've kept all the broken TTL chips over the years...
I am evaluating a TOP2004 programmer for testing TTL chips. I bought
it off of ebay from
http://www.mcumall.com/comersus/store/comersus_dynamicIndex.asp I
bought it on ebay because the price was cheaper. They are located in
Canada and it took 5 days to get shipped to Alaska. Very well
packed. The other TOP programmers ship from china/japan.
I want to be able to recommend a TTL tester to my customers of the
Kenbak kit. With 132 74xx TTL chips it would really come in handy!
So far I think it does a good job. If I lift a signal leg on a
74LS04 it both can't auto detect anything and will report a 7404 as
bad. I only have one known bad part, a 74LS376. It DID report it as
bad and undetectable.
What I'm wondering is if anyone knows how I can prematurely kill a
TTL device or simulate static failure. I'd like to try to test how
thoroughly the programmer tests the chips. It can't tell the
difference between a 7410 and 7412, but that isn't too important for
knowing the chip works (mostly)
On a second note, I have successfully over clocked my Kenbak
500%. Its running happily at 5MHz. : ) Although it gets a lot
hotter! I need heat sinks...
--I suppose giving one 12v to simulate hooking up a power supply wrong?
--Hooking 12v to a device normally powered at 5v?
--Shorting out a buffer output? (I think some buffers are designed
to be shorted out though)
--Vehicle ignition coil to an input? : D

I'm sure you hate this question, but did anything ever happen with Don
Maslin's disk collection? I spoke with and exchanged disks with Don over
the years and just tonight learned of his death.
