> Each machine would have a jumper to select either the top or the bottom 32KiB working region.

So, did anybody mod the machine by replacing the chips by working ones and making that jumper software-controllable to get 16 + 2 × 32 = 80KiB of RAM?

I googled for that, but couldn’t find it.



Yes, such mods were actually quite popular. Here is one example: http://blog.tynemouthsoftware.co.uk/2020/03/a-zx-spectrum-wi... You can buy upgrade kits even today: https://www.retroleum.co.uk/spectrum-repairs-mods


I recall reading about it in a Spectrum magazine in the 80s. While interesting, there was not much you could do with it since most software didn't need it.
