Polishing key caps
The machine I was working on here is not an HP or calculator/pocket computer but the section on polishing keycaps might be of interested to HP aficionados with faded or scratched double shot keycaps. Link below to relevant part of video.

RE: Polishing key caps
Thanks !
Ah the VIC20, bought one new back in the days as a kid !
Great machine for the time, in color and with a decent keyboard and way cheaper than the Atari 800 (cheaper Atari 400 had an awful ZX81 style keyboard).

Vic20 main issue was the stock RAM (5ko ?), i had to install a multislot cartridge holder into which i could add an 8Ko expenssion cartridge (or it was 16Ko) and at the same time a game/software cartridge....with a "magic" button that was just cloning the Cartridge ROM into the RAM.... allowing me to "save" it onto a tape.

6502 ┬Áproc programmable using a monitor in Hexa.
And i got that huge floppy disk unit connected via a serial cable.
Had also the printer.

Great system that i replaced by an Amstrad CPC464 a couple of years later using the Z80....
