Six list members have said they want to participate in a group buy of these board sets. Those are:
ML
PA
SM
DC
HB
GL
I've asked Jared for clarification on some points and for help ensuring the order is placed correctly. I'm waiting to hear from him.
I'm inclined to place the order with the same board house Jared used. I'm not willing to go into a lot of competitive bidding on board cost! I don't know the cost of a set of four boards but it can't be that much...
I live in Southern California and am retired so I can manage a group buy, with reimbursement via PayPal Friends and Family. There is a very special PWB-mount rotary switch required; I may buy a lot of those to ensure availability so that would likely be part of the board set purchase. Be aware this is a $25 switch! Many of us have other standard parts available so I'm not enthusiastic about buying other parts.
So, think about really wanting to build one of these testers and let's see if we can make a group purchase work.
I'm currently building a GPSDO into a TM500 proto module. But, any non-working TM module can be bought and stripped to provide the chassis structure for this tester. The PWB set makes is easy...
I welcome your constructive comments. Note the cost of the rotary switch stated above.

Hi all,
I have been accumulating TM500 modules and mainframes for a little while, so I recently finished building an 067-1201-99 TM500 mainframe tester from the Tek construction notes floating around.
I updated the design somewhat and designed it for simplified construction (Not a single wire to strip and solder!) and I thought someone here might be interested in taking a look or even building one themselves.
Here's a link to the youtube video:
And here's a link to the google drive with all the gerbers and schematics and stuff. I went so far as to rewrite the manual with the alterations and corrections included.
Direct link to the new manual:
Let me know what you think, and let me know if you see any errors that need correcting. :)
Regards
Jared.
