Subject: Undoumented 6502 opcodes : BBC vs. Electron

I'm fairly sure on here a while ago someone stated that the 6502 in an
Electron reacts differently to at least some undefined opcodes when compared
to the 6502 in a BBC Micro (specifically with reference to Zalaga I think).
Is that correct, or did I misunderstand? If so, is that to some of the
values, or all of them?

If it helps the 6502 in an Electron in an SY6502A, from a company named
'SynerTek'.

-Thomas
