I find my collection of random old cards overflowing and I have picked
out six random PCI/AGP cards on the offchance anyone is interested
- Hauppauge PCI WinTV
- ES1371 AudioPIC (x 2)
- PCI Audio/modem card
- ATI AGP Rage Pro 109-73100-02
- ATI Radeon 9550 128M AGP

Are the cards of any interest to people? (for the price of postage or
collection from London, UK :)
I may also have a phenom 9550 with its motherboard, some and a
selection of PCI plus IDE/SATA network cards - let me know if I should
go digging...

I remember meeting him at a COMDEX or maybe a West Coast Computer Fair
once upon a time. He was selling prints. I recognized him. His booth
wasn't getting the traffic it deserved!

When I have time I will check it carefully, I think there may be clues about Q414. Interestingly the intro says that horizontal section is not intuitively understandable from an examination of the schematic and it is a likely candidate for failure because of high stresses in the components.
I forgot some th-of-op was also included there, and then found it again tonight in another document:
vt100.net <http://vt100.net/> has a work-in-progress html version of some VT100 Technical manual:
https://vt100.net/docs/vt100-tm/ <https://vt100.net/docs/vt100-tm/>
There doesn’t seem to be a document date there but Chapter 4 has that th-of-op section on the Elston monitor:
https://vt100.net/docs/vt100-tm/chapter4.html <https://vt100.net/docs/vt100-tm/chapter4.html>
Section 4.8
Neither of course has the schematic, but notably these th-of-op sections reference component IDs that match the PCB & your RE'd schematic, and the small th-of-op diagrams do show Q414 as PNP.
The T403 pin numbers there differ from your labeling as Digital/Elston viewed it as 6-pin with 1 & 5 absent, rather than 4-pin.
Your pics show what appear to be some date codes from 1979.
The vt100.net <http://vt100.net/> website is aware of other field printsets from 1979:
https://vt100.net/manx/part/dec/mp-00633-00/ <https://vt100.net/manx/part/dec/mp-00633-00/>
but they also cannot find them.
So it does appear that, in addition to the Ball monitors, there were two versions of the Elston monitor for the VT100:
- one from 1979 with PNP HOT,
- one from 1982 modified to NPN HOT (along with other mods) (per MP00633_VT100_Schematic_Feb82.pdf)
Double-checking with the pics, your schematic looks correct to me regarding the HOT circuit.
Looks like the board could be modified for NPN with 1 ~ 3 trace cuts depending on how one went about heatsinking the HOT.
Or use the search specification selectors on sites like Digikey or Mouser to find an adequate hi-V PNP power transistor.

Dear administrators,
Once again Gmail users appear to have been disabled. Could you please help

Thanks and best regards

I bought a reel of paper tape at an office supply shop today.
It was in their 'bargains' room and is marked
NCR
SYSTEMEDIA

It cost me £0.50. I think they had two more reels. it's age is indicated by
having a London phone number that was made obsolete 30 years ago.
However, what surprises me is that it's 17.5 mm (0.69", 11/16") wide. This
seems too narrow for 7-hole tape and too wide for the tape used for
telegrams. Is it for 5-hole tape ?
