Bio

I might not be entirely neurotypical...

...and I sometimes apologise.

Born in London & based near London, UK.

I studied electronics engineering and love it. I find that it gives me a low level view of what systems are doing in my work with computers.

...and I work with computers a lot. I'm currently lead eng on some large gov cloud infra.

Been using Tek scopes for many, many years as a hobbyist.

I own a couple of scopes not on this wiki.

My life has changed a little and I've had to refine my planning... I've acquired a lot of equipment and it's quite a burden to catalogue, triage/assess and then plan for actual preservation and restoration... I'm looking forward to giving my favourite hobby more focus in my life - even re-organising my house to support it more...

Things I'm working on

Testing plugins

English has a habit of tripping us up... Especially as we use a variety of regional dialects here. I intend to create plugins for testing the mainframes, their power rails and some minimal features. Hopefully, along the way, I'll also gather ideas and notes to create test rigs for testing and calibrating plugins...

Inspired by some excellent plugins from Tek, Jared@NFM and others, and the fact that probing the backplane with test gear is a Royal Pita, I've cobbled some notes and parts together and intend to build something to test Telequipment, 7000 series, 5000 series and TM500 series mainframes.

Octopus

I have a 7CT1N but like the idea of making some of our old scopes more useful by adding something like the octopus idea... At its simplest, the octopus can output X-Y to a scope. With storage, we can compare traces with known-good components. With programmable hardware, we can run complicated and automated tests.

Repairs

I love repairing electronics - it's been a hobby for many years. I find it therapeutic to restore things to working order, as well as rewarding to see something recovered from a path to landfill. It's a fond memory of mine to have been greeted by nephews and nieces with excitement and pleas to get me to repair things they'd liked to play with...

I've been buying Tek and Telequipment gear cheap to support sharing my enthusiasm with folk wanting to learn about electronics. Some of the items I've acquired need repair! Some might be rare enough that I need to plan the work to include pausing for photos or even good lighting and commentary for video...

I'll add a table here ASAP as I think that I'll need to solicit info and encourage discussion...

I opened up a barn find 7904 and am disappointed to find that it has a dummy board where the readout board should be ie, it has the dreaded Opt. 1... On the plus side, after a little cleaning, I found that the layers of guano seem to have protected the outside somewhat... I'm very pleased to find that a spare readout board I have from a 7603 was the same as used in the 7904

I also have a 7504 barn find in similar condition...

I was going to create the 11201 repair page today but didn't complete anything worth sharing - except updating a few pages and reading some manuals. The diagnostics section of the ESM (for the 11401) is nearly 300 pages...

Notes for other users

Help Wanted

I saw someone on the TekScopes group had new shafts and acrylic skirts made for his scope - I was very impressed with the result and I'd love to find someone who can make some for me in the UK. (He's somewhere southern in the USA.)

3D models

I have a 3D scanner which might help when we need to share details of parts, etc.

I have also become quite proficient in producing CAD models when I need to fabricate parts.

I plan to share things eventually anyway, but if there's anything I can help with, don't hesitate to let me know.

Photos and scans to add

I have some items for which there are currently no photos on the wiki. If you need anything, don't hesitate to ask in the item discussion page - I'm sure that you'll get our attention and motivate us to prioritise taking photos. The only items I currently remember are summarised here.

Colours

Gianni's book mentions that he used RAL 7034 to paint 3D printed knobs... Online, it looks too yellow - but on Gianni's scope, the colour looks correct!

I intend to collate colour info here. I'd love to find some original documentation and extract colour info...

PolyMaker produces a PLA filament which is the closest I've found to that required for a new scope cover:

  • PolyMaker Polyterra

  • Covers I printed for 46x scopes

Plugin Interfaces

Not sure if these photos have a place on the main wiki - the 7000 series are a lot deeper and a fraction wider. The TM500, 5000 series and Telequipment plugins share the same chassis glide extrusions - but locations and widths of the glide keys and pins on the backs of the plugins prevent mishaps :-). The 11000 series is almost identical to the 7000 series but for the top optional connector which is shaped to prevent plugging into the wrong frame.

The TM500 and 5000 series interfaces are very similar to the JAMMA (Japanese Arcade Manufacture Marketing Association) but some connections are paired and some have a notch which removes a connection position.

Connector summary

The various mainframe and plugin interfaces have different pitches to keep us on our toes. While the Tektronix seem to be numbered from the bottom of the connector, the Telequipment are numbered from the top.

TelequipmenT Type 43

I've got a manual for the TelequipmenT Type 43 (D43/D.43/D.43R/S.43) which is from 1965, the one on this wiki is newer - I think that mine is from before Tektronix bought Telequipment. The one I've got has appendices for plugins D, G and H which are not in the 1968 printing. I see that there might be separate manuals for the plugins on the wiki - I've not checked all three but I see that my appendix for the H plugin has different content. All I've spotted so far is that the one on the wiki doesn't list all of the transistors (though the schematic shows the types) and is missing the two variable inductors, L21 and L22, which are listed as: 

2.2/5.1μH Variable Inductor (Brown/Yellow)

I might add this to the H plugin page or its Discussion section.

Repair notes

Some notes for going to other pages when completed.

LiI cells

I have Lithium Iodide cells in a 1240 and its 12RS01 RAM pack. Stamped 1983 and still showing 2.75 V in circuit with some bulge... I think that cell will get its own page for linking from the various device pages which contain one.

Notes to me

Misc videos


Wiki editing

I need to remind myself to refer to the style guide for this wiki:

...and the Category Tree ...and Article Templates ...and a couple of extra handy references


Table Generator

Have a look at this link!

If you see a table you want to edit, copy the rendered table from a page viewed in your browser (ie drag to select&highlight, then copy with Ctrl-C or right-click, copy) and paste it into the editor ("File", "Paste table data...") - from there, you can transpose/pivot and transform the table!

Using that in my workflow for dealing with large tables, I can readily create tables for the wiki... I can import tables from the wiki and export as Text, Markdown, HTML or Download as CSV, all of which are useful steps to import into a spreadsheet to further manipulate and from there, then import back to the wiki via the TablesGenerator. Bliss!

Parts

I've got a few notes re parts refs and BOMs for various scopes - I want to collate and present them here eventually. I found a couple of useful sources and need to be able to find them when I want them... This wiki is perfect for that.

I have over 1800 parts refs, many with generic part refs for ordering. I'll not share them until I improve them (some conflicting info needs cleaning/refinement).

Screws

In the UK, UNF and UNC threads are relatively rare and expensive with metric being the norm.

Parts to identify and catalogue

151-0500-00: Transistors (Special)

I was given a box containing bags of Tektronix and Telequipment parts, one bag was labelled 151-0508-00 and contained what I think might be BC203 transistors. I'll get them onto a curve tracer to confirm the characteristics. 

Tektronix 151-0508-00 transistor. May be BC203

Working with PDFs

Extracting Part Refs

I had fun extracting lists of references to the 151-0367-00 transistor from the 475 service manual.

Get the text from the manual 

$ pdftotxt 475_SM.pdf 475_SM.txt

The tables are split but remarkably consistent so it's not too difficult to work back and pick up the previous column 

$ grep -B12 151-0367 475_SM.txt

Grab the refs I want and paste them into a text editor, then turn new lines into comma space...

I'll come back to this - I intend to simplify extraction of parts lists and other info (eg Manual change appendices) from the manuals so we can have useful cross reference and more.

OCR

The upload tasks page recommends that we overwrite a PDF if we OCR it - then all existing links would continue to work. I think that we should share more info about good OCR methods as mine seemed to be less good than ones I download from this wiki. I'll share notes about what works for me...

`ocrmypdf` seems to work very well - the recognised text lines up with the image text - best results so far.

Can extract pages from a pdf 

$ pdfimages --all infile.pdf infile-extracted    # the last argument there is the prefix for the output file names

Remove any duff pages, rotate any pages which are better rotated, then img2pdf and ocrmypdf to rebuild the pdf

Create PDF from images, forcing the page sizes 

$ img2pdf -S 176x235 --rotation=ifvalid  *.jpg  --output TQPR.pdf

Running OCR 

$ ocrmypdf T940-letter-June-1983.pdf T940-letter-June-1983-OCR.pdf

Editing OCR results I've found a utility to uncompress PDFs to ASCII - once uncompressed, we can edit text by hand... 

$ pdftk 070-1234-99.pdf output 070-1234-99-uncompressed.pdf uncompress

^^^ This is failing for me recently - the uncompressed file doesn't have the plain text once happy, we can compress again: 

$ pdftk 070-1234-99-uncompressed.pdf output 070-1234-99-fixed.pdf compress

I'm hopeful that I'll be able to script some useful features for my PDFs in future.

I've had a couple of errors with ocrmypdf when working with some of the files taken from this wiki - most recently, a pdfmark destination beyond the end of the document. I'm pretty sure that extracting all the page images and rebuilding the PDF from images will drop all the extra data from such documents - and maybe I'll find the right combination of options to ignore them or even fix those rogue pointers...

Experimental pages

RPR tables

Struggling to use the RPR documents, I created a summary of a couple of parts to help practice.

The first I tried is for the 2N4261


2N270 151-0007-00

Replaceable Part Record References

The table below is a very brief summary of data about the 2N70 from the RPR and other sources.

Tek part # RPR Used in Also used
151-0007-00 2N270 RM567, 567, 110, 519 151-0071-00
151-0133-00
Tek part # RPR Used in Also used
151-0089-00 2N962 544, 546, 547, 519, 4014 151-0188-00 (250 MHz)
151-0220-00 (600 MHz)
151-0228-00 (600 MHz)
151-221-00, 156-0089-00

Remembering to add Category:Transistors

I might use this section to help me flesh out data before populating pages... there's a chance that we can use existing cargo tables to achieve something similar... If User:Peter's free, maybe he can work some magic... Maybe this isn't worth doing for all transistors - maybe it'll spring out of need when replacing some common parts. The RPR for ICs might be more important but might have fewer equivalent parts to chase down.

Fractions

I learned recently that the thickness of the 7000 series plugin PCBs (and presumably others) is ⅟16". There's no unicode symbol for that so I thought I'd try and take note of these options:

Discontinued active probes

The table generator gives me the column per line style which I convert to the line per line style using: 

{  while read A; do [ "${A}" != "|-" ] && { OP="${OP} |${A}"; } || { echo ${OP}; echo ${A}; read OP; }; done; } | sed -e 's/||/#/g' | column -ts '#' -o '#' | sed -e 's/#/||/g'

...but it's still confusing with rowspans. Luckily a short table so hand-editing fixed it.

Testing these large tables on mobile is confusing: I see strange text formatting anomalies when viewing large tables on mobile - some text large - but good otherwise...

Voltage probes from 1969 catalogue

I think that the best way to work with tables is in a spreadsheet so I get all my favourite editing options before exporting to wikitable... If I'm going to import the page reference columns from multiple catalogues, I need to think about how I might best present those in a single table, if at all.
