Thanks for all your helpful replies, which are going to find their way
into an AppleWin improvement soon, if all goes well.
I'm still not quite happy with some ugly details that I haven't seen
documented too well:
1.) Operation of ARR ($6B) when the decimal flag is SET.
2.) Exact operation of decimal mode ADC and SBC in both the 6502 and the
65C02.
I'll take a look at the VICE code first. Do you know of any other GOOD
code for this?
Best wishes,
