We've been having some good discussions on the Discord about the СИСТ expansion connector, and @adamradipat1715 reminded that the Байт has a BIST (built-in self test).

So, confirmed the BIST ... took a little practise but I got it to work. It only works in the БАЙТ mode (СОВМЕСТ button pushed in) ... not the ZX Spectrum compatibility mode (СОВМЕСТ button pushed out).

If looking at the Cyrillic key text:

Hold down [Ы] [В] [А] and press [СБРОС]

... or, it looking at the Latin key text ...

Hold down [S] [D] [F] and press [RESET]

After that I tried loading "The Rocky Horror Picture Show" again, ensuring the [СОВМЕСТ] compatibility button was out for Spectrum mode. This time the game seemed to work, although I still don't know what keys to use (duh, do preparation and look them up first).
