The Imlac PDS-1 I have has a similar problem, but not nearly as bad.
Though it is itself in less than stellar shape. You can see it in the
pictures on the Blinkenlights site I posted.
of mine if I cannot find a replacement tube. The test
constists of building
an enclosure with a pan in the bottom in which I can soak the face of the
tube in acetone in order to disolve the resin which is between the face of
the actual tube and the plastic protection layer. If the two can be
separated in this way, then the plastic can be re-attached to the tube
with a new layer of resin. This design is similar to the process used to
hold camera lenses together as they are often made up of multiple layers
of glass. I have a friend who repairs antique cameras and he suggested this
approach. As someone else noted, it would not be safe to operate the tube
with out the protective layer, but I hope that with careful handling, it
can be repaired back to new condition.
Wouldn't this require potentially harmful amounts of acetone?
The console in your picture is also different than
that of the PDS-1.
You have a wood enclosure and mine has what I think is a fibreglass
enclosure. More importantly you have a knob and mine has some discrete
switches.
The PDS-1 did not come with one so I have no basis for comparison, other
than a photo I remember seeing either in a manual or on some website
(maybe yours?)
The keyboard on my PDS-1 is detached, but is
molded/styled to match the
display enclosure. Interesting on the memory. Of the different models
I have seen, the memory does seem to move around a lot from design to
design.
Interesting...the terminal on my PDS-1 is one piece with the CRT. Mine is
serial #12 :)
It would be great if you get the machine up and
running for VCF 5.0! I
have been considering bringing my this year as well, so if we both do,
perhaps we can "network" them...
That would be perfect, and would complete the exhibit as I intended it.
Do you have the prints that you need. I have prints
for all of my
machines, but they may be different enough that they would not help
you. Let me know if I can be of any assistance.
Yes, I do fortunately. Also, John Tinker was kind enough to send me his
batch of documentation, which is mostly PDS-1D docs as well. Thanks,
John...and I am planning to get your docs back to you at some point! :)
Your pictures have inspired me to put up a better set
of images on my
site. I will try and do that tomorrow...
Great! I'll be interested in checking them out.
