Grammont Fotos TM Thermionic Valve

Sorry, I thought this deserved a separate topic :oops: This little old valve was one of the first hard vacuum valves ever made in WWI.

Not bad for a freebie! They are pretty basic (no pun). I don't think they had the charm of a zx81 :)
Cost me £30, nearly free :lol: Are they as bad as a ZX81 :shock: I thought I saw colour video on the interweb :? I guess the low amount of RAM is the limiting factor ... :?:

VIC 20 - very low serial number - 0415 !

I have had a slight hankering for a Commodore PET for a wee while, not sure why, then a gentleman at work offered me a VIC 20 in a box (a baby PET by all accounts), a bit yellow, but no more information. I opened it up (the box) and have come to the realisation it is pretty early/old. Late 1981 old ...

Re: Thermionic Valves

This one (the bigger one) I think is from 1919. 97ACE75C-D3CB-4000-A767-18892181294C.jpeg You can just about see 19 across the NT10. The NT stands for Navy Transmitter as far as I can Google. The form factor is similar to the 1916 one. A lot of this early stuff was pushed forward by WWI as far as I ...

Hi Martin Funny that your picture shows a ZX Spectrum box on the top shelf. As the term "Shoulder of Giants" reminds me of Geoff Wearmouth's ZX-81 "Shoulder of Giants" ROM.

Re: Standing on the shoulders of giants - Ponders End Middlesex

Interesting collection and story. It reminds me of the story in the the thread "Thermionic Valve" about the wartime, Phillips and Mullard. It was clearly no accident that a large manufacturer of lamp bulbs ended up making radio valves too. The "standing on the shoulders of giants" concept is very i...
