According to the 1987 Common Design Parts book, all three are TMS4100 character generators. TMS (TI) 4116 and 4164 are 16 kbit and 64 kbit dynamic RAMs, respectively.

Perhaps used in (27xx) Spectrum analyzers?

Yellow book says TMS4100 (and deleted) on them, which would be a TI 4116 or 4164 or other memory. Maybe a Wilsonville product?

Ke-Fong LIn,

Thanks for setting up these scripts. I'm modifying them to create card edge connectors for some vintage HP interface cards. Probably do some extender cards too, once the footprints are in the library.

Much appreciated!

Re: More hard to find Tek parts, and a great EPROM programmer

My experiences with Sphere have been like the others who report good
experiences. I have bought slide rules as well as electronics. Shipping has
gotten very expensive, though I have discovered that you can save shipping
costs if you have an account with the shipper - particularly FedEx. I
shipped two large (two boxes about 20” cubes) with microscopes in them. Yes
- I overpack them having received broken microscopes because shippers did
not know how to pack them. Anyway, the recipient said to use his FedEx
account because it would save on shipping. Did it ever. I have shipped
boxes like that about the same distance and having the same weight and paid
well over $200 for both. The cost to the recipient for these two? $38. Now,
the pricing may depend on your shipping volume, but this was an account
number for a university. Personal accounts may not save you quite so much.
I’ve set up an account for myself and have a couple of more microscopes to
ship, so I’ll report back on how much it costs/saves.

I usually factor shipping cost in when purchasing something. I had an
unusual experience with an eBay seller. He offered to sell me the HP
counter I had looked at for $1.00 plus shipping. He is in Canada. He knew
what the shipping cost would be, but at a price of $1.00 for the item - no
customs. The shipping wound up being about $120, but $121 for that counter
was a good price. Even if he only got $1.00 for it, he got it out of his
“inventory” so I guess it was worth it to him. It was also one of the
best-packed pieces of test equipment I have received (noting that Sphere
does a great job also).

Sphere seems to be a great source for old TEK parts but as most people

Re: What to do with these files?

Paul,

By all means, make the software and associated docs publicly available.
Even without a 2402 they should be usable with any PC compatible computer that can properly run DOS apps (not under any recent Windows!).

Re: 5000 series power supply potentiometers

Thanks for the references Ozan.

I've been studying Mouser's catalog. Looks like Amphenol makes a fair equivalent:
https://www.mouser.com/ProductDetail/Amphenol-Piher/PT15LV18-101A2020?qs=sGAEpiMZZMtC25l1F4XBU%252Bo9fLf9DWN0PIofWswK870%3D

I hesitate to order from Mouser with the $8 shipping (for a couple/few $0.80 parts), but given what the #### on eBay is expecting to get for actual 311-1120's I'd just as soon order from Mouser.

Or a local dealer. I work in the South Bay (going back to the office for my first real RTO visit Monday), so a side trip to Anchor or Excess might well be worth it. Need to research their catalogs/inventory first.

Re: What to do with these files?

I'm getting a number of votes for TekWiki, so I will do that as well.

I'll post them up after I reformat my old web pages into a pdf to
go along with them. Probably take a couple days as I have some
higher priority tasks right now.

I also want to validate any of the links; I wrote that seven (!)
years ago and the web has changed a lot since then.

Gad, has that 2432a been sitting in the repair queue that long? ...

Looks like my tired brain typed in a cross of two part numbers - crossed rows in the E Parts List. Not as bad as crossing streams, but yeah, there ya go. SUE - stupid user error.

I have some 10k pots that go down to 30 ohms that are of somewhat similar construction. I'm going to try soldering/hacking one in while I wait for the eBay seller to contemplate my low-ball offer for two trof the 311-1120-00's. I can/could/will head down to San Mateo Electronics to see what they have. I need to get some teflon wire to repair some overheated ones between the Z-axis board and the CRT. I think I saw an interesting Y-tube video of someone examining the beads-on-a-string pattern wire makes when heated to failure in a vacuum. Looks like that, only more like braided string. Weird, but fun.

Back on topic - my query really was, how are these pots colloquially referred to? Composition pots? Something else? What can I search for online that's similar, if not the same, in the modern supply chain? I'll pay this eBay guy for instant gratification purposes, but I prefer to find like-kind replacements over hacking something in. It's like trying to match Tek-blue paint. I don't have to, but would like to keep to original as much as possible. These seem so ubiquitous in the 5000/TM500 realm that I'm surprised I'm not finding them on Sphere, etc.
