UPDATE! Re: Successful workshop January 14&15, 2017

Hello All;
 
Newbe here.  I will take Jeff Brace's advice and detail what I worked  on 
that was pix'ed.
(See Jeff's link to the Google drive where the pix are located)
 
I have been working on the museum presentation of the EAI  TR20.  So far, 
the restoration
has been behind the scenes.  Visitors will see the computer in a  blue 
rack, sleeping.
 
We pulled all the amplifier trays from the computer and then put the patch  
panel back,
thereby allowing us to work on the defective components without disturbing  
the display
and not making it any uglier than it already is.
 
The large spaces between the computer are destined for a flatbed  plotter 
(above)
and a storage scope (below).
 
With the new fabricated test bed (pix), we now can test and repair the  
amplifier trays
at our convenience (workshop days).
 
The pix that Jeff took of my stuff are as follows:

out.

ALIVE!
IMG_5067.jpg:   Test extender cable is firing  up an EAI TR10/20 amplifier  
tray.
Farm fresh picked from the boneyard storage at my  warehouse,
and it WORKED FIRST SHOT!
(Parts and tray components are from my collection.)

multimeter)
I've jazzed this up with an internal +/- 10v reference supply.
This is nice eye candy while doing repairs, and it has the same look and  
feel of the 
TR20 front panel.   50 year old technology diagnosing 50 year old  
technology.
 
Just thought others might want to share in the progress and joy!
 
I will continue diagnosing museum components at next workshop (Feb  11-12)

Just wanted to write a quick e-mail to thank  all those who attended the
workshop. It was another successful workshop. It  was a good idea to have
the workshop in the bigger space. It accommodates  more people.

A lot of things got fixed and there was a lot of sharing  of knowledge and
expertise.

Here are some phones from my iPhone  which are raw, unedited and not the
best quality (sorry I forgot to bring  my Nikon):

If  anyone wants to chime in on what the worked on, their progress and  what
they need to work on next.
