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...
Cheers,

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.

Hello Larry,
I hope that I am not too late in requesting a complete board set for the

TM500 Mainframe Tester.

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,

Rick.

This is another update on the group order for circuit board sets for Jared Cabot's TM500 power supply tester.

I just yesterday remembered there is a Tek500 groups.io Group specifically for TM500 equipment. I asked there for interest in the board sets and got several requests to be included; that has expanded the list to 63 committed and still 2 more with incomplete information or lack of commitment. Please check the two lists of name initials below to ensure you are shown correctly.

It is interesting that, while most of these are in USA, there are also members in UK, Canada, Australia, Spain and Germany.

In light of the size of the circuit board order remember that I must ask for prepayment by PayPal Friends and Family before I can place the board order. If you have any problem using PayPal Friends and Family as a means of payment, please contact me off-list.

Final board set cost is still being worked but the estimate is $38. Packaging and shipment to CUSA will be $10; international shipping will be higher and I have discussed that with those several.

Note that Jared has released another update to the Gerber files.

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.

Tom,

I've been reading everything that I could find about the 485 since this
discussion started, and the one thing that I can't find is any mention of what
probe would have been standard with the scope. The 485 was released the same
year as the 475 (with which I am quite familiar). The 475 would have shipped
with P6075 probes (or maybe P6063 probes? My father's scope, which he started
using in 1975, was shipped with P6075A probes).

The manuals for the 475 clearly list what kind of probe would have been
standard equipment with (and, apparently, were specifically designed for) the
scope. Depending on which manual you look at the 475 manuals list either the
P6075 or the P6106, but I haven't found any such listing in the 485's manual.

I've been using cheap Chinese 200 MHz probes to test my new (to me) 2465, and
the effects of the probes' bandwidth are evident. What probes would have been
used on a new 485 in the early to mid seventies?

I just discovered the printed receipt I received from the post office
last week (when I mailed Peter Keller's books to US addresses)
contains Estimated Delivery Dates. It estimates that ALL of the books
will be delivered to you by this Monday 1/11 at the latest.

Books to Florida addresses will arrive on Monday which I can
understand since they are the furthest from Seattle.

Books to New York State and New England addresses will arrive on
Monday although one book already arrived at Zip Code 06851 in
Connecticut yesterday, 1/7.

Hi!
Does anyone have a spare 2712 GPIB board available? I am using a Prologic GPIB to USB converter, and the setup had been working great for a few years. Abruptly it ceased communicating, so I tried a spare Prologic converter, but that did not fix the issue. At that point I assumed a power issue with chassis differential (power spike?) between the PC and 2713 was the culprit. I replaced the two GPIB interface ICs U170 and U370 as well as the dead battery, but I still cannot plot through it. When Plot is pressed I get a No Listener message, even though the PC sees the Proligic, and I know it is good, so I suspect some other GPIB board issue.

I tried ordering a TMS9914A GPIB IC, but the only version available is a really small SMD (I forget the case outline style) which is not pin-for-pin compatible with the much larger one on my board and I don't have time to make an adapter PCB....if that is even the problem I hope someone has a spare board #671-1859-01 to sell?
Thank you for the bandwidth,
Howard Hoyt

Don't known where Jim got the idea for the pulser but in 1962
I built this circuit with the delay line as an engineering technician.
While at GE Comm Products Lynchburg, Va Military Engineering
Dept long forgotten why we were doing this.
We where not testing "o" scope.
