I'm now ready to take orders for P112 kits from people who didn't get
onboard the Kickstarter project. For a complete kit (board and all parts
that solder or plug into it), the cost is $200 to addresses inside the US
-- $215 outside the US. If you want one (or more) please email me with
your Paypal address so I can make up a proper invoice. Alternatively, I
will accept check and money orders.
If you want Terry Gulczynski to build and test the kit for you let me know
and I'll get that set up. If you're outside the US and want this service,
you can pay the inside-the-US price. I'll ship the kit to Terry. He'll
charge you for his services and ship you your board. If you want to order
a GIDE board at the same time, he can do that too for you. He'll also
sell you the GIDE board by itself if you want to build it all yourself.

I'll bet they'd love to buy lots of R at RE gold plated IEC to BS1363 power cords.

Hello.
I'm trying to identify some DG boards using the 107-xxxxxx-xx numbers.
There's a reference list to associate these numbers to the product series?
BTW, the numbers I have are these, with draft descriptions:
ALU Arithmetic Logic Unit Board. 107-001627-02
Dual Video Board. 107-501548-01
Disk Controller Board. 107-000375-06
ILC Intelligent Local Network Control Board. 10700205403
Disk Logic Board. 107-00089104
Servo/Clock Board. 107-000738-01
Sync / Async Controller Board. 107-00083404
MVII Bus Repeater. 107-00218501
Thanks

The old IBM terminal is gone, as is all of the Display Write stuff.
The HP terminals are also gone, as is the original Apple ][, and a few of
the Apple single floppy drives.
The Apple III is also gone, but the Lisa is still here.
Those who wanted things (other than what is sold above), please email me
again, and I will get you pics and requested prices.

I was looking to see if there was a patent on the 3M Kappamat format, and came across patent 4422111

Fantastic! I got in touch with Hector Parr, and he directed me to a
memoir he's written, and I now have a story: One Alan Wilkinson wrote
the book 'Computer Models' (a copy is now on its way to me) which is
most likely inspired by Brian Crank's article series. Alan was
teaching at Spennymoor Grammar School, and Hector was teaching at the
nearby Darlington Grammar School. Hector read Alan's book and
proceeded to get the Maths department and pupils to finance and build
a machine called DENICE, designed from scratch but with inspiration
>from the book.
Alan moved on to Teesside Polytechnic where he looked after an IBM
1620, which was made available to schoolchildren.
Hector later taught at Barnard Castle School, where he was
photographed in 1978 with a different computer:

His memoir can be bought at
http://www.lulu.com/shop/hector-c-parr/music-maths-and-machines/paperback/p…
- there's a copy of this too on its way to me.
I now discover that Alan's book has been referenced at
http://en.wikipedia.org/wiki/Transistor_computer#cite_note-15
since Nov 2010.
(As for the reported cost of ?50 in the late 60's, I'm told a weekly
shop for a couple would be ?2 and a pint of rough cider would be 1/9d
(that is, 21 old pence, which were 240 to the pound.) According to
http://safalra.com/other/historical-uk-inflation-price-conversion/,
the project would cost ?750 today, although those anecdotal prices
suggest rather more.)
I wrote up some notes on the WW machine here:

One of my HP 2113B CPU's doesn't boot the right way, after switching it on
all lights are on except the over flow light which stays out.
I know it should be an memory error, but removing all the memory boards and
starting with a known good memory controller and memory board gives the same
result. Because the PSU has the power fail option and I removed the
batteries and placed the plug at the battery in connector, I now suspect the
PSU.
The voltages checked out ok, except the 5M and 12M voltages come up a few
seconds (5 to 10 seconds) later than the rest of the voltages. I'm afraid
the time interval is too long but I'm not sure.
Is there anyone who knows what the interval should be ?
Or has any clou why it's not working ?

What is the "S" variant of the 11/35? It's different enough to have its fiche
but since I can't yet read the fiche, I don't know what distinguishes it from
the "regular" 11/35. Does anyone know?
Thanks,
Jack
