Hi James,
I will look into the size limit however there is probably not a need to upload 1MB+ files. Overkill for the viewing format on this forum.
Thanks.

Tried to upload three photographs and got this:-Server problem
There was a problem with submitting this contact form.
Please call us directly at 800.426.9265, 425.743.3171 or email info@huntron.com We apologize for any inconvenience.

Then I tried to upload one photograph and got this:-An Error Has Occurred!
Your attachment has failed security checks and cannot be uploaded. Please consult the forum administrator.
But maybe the photo was too big at 1.34 MB.

But did manage to get one photo on at 851 KB.

What's the limit Curtis?

Hi Curtis
Had a look on Ebay nothing there, and a search on Google showed some suppliers but not Ebay even Stateside.
Suppliers in the US seem to think your going to start manufacturing with this obsolete part and insist on silly minimum orders.
If you have the time could you email the linK to this Ebay Toshiba 85 DB31 C.R.T.

But in 30 years time if we are still here will you guys be still wanting $1500.00 plus for early versions of Workstation 4, when Workstation 5 or 6 is the current version?!?

Hello All,
I finally got around to fixing the permissions issues with uploading image attachments and avatars. Let me know if you see any problems by posting here.
Thanks.

Workstation 4 uses activation codes attached to the hardware serial number being used (Tracker or Prober) so an open password version is not possible.

Looking at my documentation for Tracker 2000, serial number less than 22A-18000 would have R46 as 220Kohms for Toshiba and 510Kohms for NEC. The NEC tubes would have been only in early units. Serial number 18000 and higher have 360Kohms and only used Toshiba CRTs. Asking around here it is possible we never actually used NEC tubes in the 22A Trackers but the circuit was designed to handle them (with a resistor change).
Also Steve, a quick search of Bay show several Toshiba tubes up for sale.

Curtis can you help here?
Just for reference for C.R.T's used on the Tracker 2000.
R46 is connected across potentiometer R45, Intensity control.                                                                       
R46 on the Toshiba C.R.T. is 220 K Ohm.
R46 on the NEC C.R.T. is 510 K Ohm.
But on my Grey cased Tracker 2000A R46 is 360 K Ohm. Tube unknown as don't want to disturb the coil, and screening round the C.R.T. while it still works.

Just noticed on the Tracker 2000 diags that at some point they must have used an NEC tube as there is a change of resistor value  to accommodate it anyone now the part number for it?
