Do you think we could extend the memory of most 8 and 16 bit home computers? I'm not sure how your defining "most" home computers, but the c64/128 & apple ][

I'm not sure how your defining "most" home computers, but the c64/128 & apple ][ line were some of the most popular and they definitely had ram upgrades.

The soldered laptop ram thing, is fairly recent and by no means universal. I suspect it would be rarer than it is, if retailers put a little note on the machine descriptions "upgradeable RAM/upgradable disk" but they can't even be bothered to put the cpu clock rates (or sometimes even the core count) on the machine descriptions.
- pjmlp 6y agoThat is something that gets plugged on the external ports, as I mentioned. Which I do confess never to have seen, as C64 and Apple weren't anywhere to be seen in the Iberian Peninsula.
- StillBored 6y agoWell, ram upgrades on those machines didn't just plug into slots. Various C64 upgrades were replacement RAM chips, or piggy backed on the existing chips. Same for the II line, although frequently there were RAM upgrade slots (like the IIGS for example). But beyond that most of these machines had the ram and slots in the same clock domain (aka a "local bus"). So a plugin card's ram basically ran at the same rate as the onboard ram. Of course there were often banking issues on the 8bit machines, but that happened regardless of where the ram was located as things like the 128k IIC (a machine without slots) were banked from the factory, and various mod level upgrades replaced various chips on the board, until the later revisions when apple provided a sanctions mechanism for upgrading the machine to 1M.
