Re: I built a TM500 mainframe tester, and updated the design. Someone might find this useful?


 

It occurred to me that if one were to successfully use a 7000 series plugin frame, the frame would stick out significantly, and allow you to have extra (and ventilated) room.? It wouldn't be workable with the current board set, but might be useful for a "checkout" style project.

Instead of a latch, I used a small cabinet pull for the module extender I built.? I don't see a need for latches for anything short of California's "big one".

I agree, latches are different.? What I was thinking of is that the extrusions for the 7000 series, if worked upon, could be used.? I'm assuming that the extrusions are the difficult part, and if the latch is not important, it may be left out.

Good day,
may I correct you here, Harvey; the TM500/5000 use?the same mech design as used in the?Tektronix 5000 Series of oscilloscopes, not the 7000 series. ?We have had?a few related discussions earlier.
Jared, I wanted to congratulate you on your design and the time and effort that went into this! ????Particularly impressed by?the mechanical design, i.e.?how nicely the front panel mounted components fit etc.?I have searched for the 3D CAD software you used and it?seems you are using Rhinoceros, which aims the?professional designer community... That would explain a lot...

If you have some machining capability, or leave out the latch, you might
be able to use the rails from a dead 7000 series scope plugin.? The
extrusions seem to be the same size, width wise. They are, of course,
longer and have a different latch mechanism.

Might be useful to check.

Hello Larry,
Thank you for confirming and offering to add me to the list ?
Estimated costs are ok ?
My details as follows:
Rick LE GUEN
12 Bayvista Rise
Somerville
Victoria 3912
Australia (not Austria ?)C

Since I did not read the very original message of this post, can you please
clarify/confirm that the scope of supply is for PCBs only or other?
BOM included?
I am currently looking for an empty or U/S TM-500 module or a series 5000
module.? Please let me know if you have or know where I could get one (I do
know that they¡¯re like chicken teeth ATM) ?

Cheers,
Rick.

Rick, I need your full name to proceed. I can still add you to the list
of purchasers but you need to be aware postage by First Class Package to
Australia will be? US$27.75 plus US$5 for packaging. I'm reasonably
confident the board set will be priced at US$38.

This will be a flat package, not a box (which costs lots more), and
there will be a stiffener to prevent bending.

If at all possible, please include me to the list and advise of the
total cost including shipping to Somerville Post Code 3912, Victoria,
Australia.
Cheers,
