I've been hanging around the dumpster again....
I salvaged some DEC pro-350 parts. I don't have a 350,
so they are available to anyone for the shipping cost.
I'm not sure if the numbers are the actual part numbers,
They are whatever I could find on the boards.

Anybody out there familiar with the Bigboard II? I have one, and rather like
some features of the thing. One of the features in the rom code is that
it'll look at the second rom socket and try some sort of weird CRC algorithm
on it and if that checks out transfer control to the chip. Problem is, I
don't understand the code.
Also, somewhere I have this 286-based Zenith "laptop", non-functional the
last time I tried it. Anybody know if there's any service info out there on
this thing? I used to be a ZDS service center way back when, but we stopped
doing that when they moved all of the training to Chicago and required
several trips a year plus _paying_ for the training to continue with it (more
than we made working on their stuff), and so I never saw any service data on
that sort of thing, though I do have some on their earlier stuff, and
monitors, if anybody needs some. I do remember seeing one of those in
operation one time, and it had a real pretty blue-lit screen. :-)

Damn, that's a cool find, even if it's in a box you already have!
What do you think, Don, hHow many exist of this panel?

Hi,
I *finally* managed to get a board assembled and tested. All of the
documentation has been written and is available as a PDF on my website.
I still have to get the documentation to the printer but they should be
back this week.
The KM11 replica is now available for order. Please consult my website
(www.shiresoft.com) for ordering instructions.
As I had stated previously when I did the prototype that the design was
based upon Tony Duell's design. Here's a link to the original post to
classiccmp

I just got some new ribbons for my Teletype 43 and the print was
(at first) nice and dark. But it soon started to fade. I watched
the ribbon while printing and it didn't move!
(There are two rollers on the left side of the typing unit which
allow rotation only in one direction, and the ribbon is a
continuous loop reinked as it passes through its cartridge,
mounted at the right side). So obviously when *something* moves
the ribbon, the ratchet action on the rollers prevents it from
reversing direction, so there is net motion of the loop in one
direction. It looks like the ribbon is intended to move during
each carriage return.
But what actually moves it? I don't see any source of friction
other than where the ribbon passes over the printhead which is
quite smooth. There is also very little tension on the ribbon
(there is a spring mechanism that holds the rollers to the left).
I don't have a service manual, just the basic operator's manual,
and can't find one online.
thanks for any assistance.

Hi List,
I have here a uVAX II in a ba23 box, most likely not powered up for 2 or 3
years.
The innards are clean, no nasty smells, no other trace of prior problems.
Even so, to minimise the risk of damage I'm going to disconnect all the 5v &
12v leads, then attach some suitable dummy load(s), switch on and wait for
smoke.
Does this seem an appropriate plan? Can anyone point me to pinouts for the
various supply leads from an H7864?
Does anyone have any other recommendations/experience of going though this
process, and is there anything I've missed that I should have included
above?
Cheers,
Pete

Hi,
Just found your board and thought you might be able to help me. I'm
currently trying to reverse engineer the code in my Ford EEC-V Engine
control unit. This unit is based around the Intel 8065 Chip set and I was
hoping someone on the board may be able to help me reverse engineer the
software in this unit, so that I can play around with the various fuel and
ignition maps and other variables in the code. If I'm really able to get to
grips with the code I'd like to rewrite it to:
Use a single coil per cylinder rather the wasted spark method.
Use a wide band O2 sensor
Gary Messick has posted on this subject on this board 4 years ago but I
don't know if he is still active. Ideally I'm looking for someone who had
exposure to the Ford / Intel 8061 / 8065 chip set as part of their work
Here's hoping one of you is able to help me or can point me at a current
email address for Gary Messick.
Regards
Phil

Hi
Although, it would be nice to find someone with
an ICE for the V25, many in our group would be able to
help you with as little as an oscilloscope and a simple
disassembled listing from the EPROM. Using a digital
oscilloscope or a logic analyzer could speed things along.
There are a few members of our group in Germany that
would be able to help you out. The 186 is a relatively
well known processor.
