I'd compare to a z80 with 64k of memory, which would be enough to run CP/M. That wouldn't allow TLS, or music playback, but it would allow wordperfect, turbo pascal, a bunch of old C-compilers, and a spreadsheet or two.

I don't think anybody would use such a machine full-time, but with a radio and a cabin it would suffice for offline work.

Of course there's no native CP/M for the 6502, but remakes have been made..
