I had a 1982 ZX Spectrum (I was a tender 24 then) with rubber keys:

that were progammed to send entire BASIC commands (GOTO, GOSUB, PRINT, PLOT and POKE) the latter used for graphics programming. Graphics was the ZX’s strong suit.
Oh, and programming with that keyboard was OK - I didn’t have anything to compare with.
But at least there was some slight key travel (unlike the Atari up there) and trailing edge trigging so as ttto avoiddddd thattt sort of thing.
It used audio cassettes for storage and the TV for monitor…I was hot sh*t with my Computer;)
These things seem like more fun looking back than they actually were at the time. True for most everything I s’pose.
