About interesting 6502 computers: do you know, that at Acorn created a SLOW computer on the same base as BBC Micro, mentioed, as one of the fastest one? They wanted to compete with cheap ZX Spectrum, like the TED series from Commodore.
The used 4 bit wide memory access (!) and very badly shared memory, made the CPU some cases run at only 1/6 of the speed.
It was Acorn Electron. https://en.wikipedia.org/wiki/Acorn_Electron
It had fantastic video modes and a huge 24KB display memory (but only 8 +8 flashy colors), and only 32KB full memory.
There are the video modes, next to the 80x25 and 80x32 text modes (what a greatness for word editors; but there was not enough and just slow RAM):
160×256 (4 or 16 colours), 320×256 (2 or 4 colours), 640×256 (2 colours): the later would be fantastic for a GUI.
But the machine was slow, and low on memory, but still ~1400 games were developped.
Could be interesting, how it may perform on the test?
