Aren't those available already? opencbm/x1541/uIEC/..

To my understanding that's not the point/challenge of Ruud's project.
I dare to say: the opposite is - do all the modifications and still
keep the compatibility level high.

Nice idea (even if already realised probably more than once in
slightly different forms), why don't you go for it? Also (as

I would prefer not to distract Ruud from doing things that haven't
been done before and he has a chance to do it. Since those are not
commercial projects, nobody is under Time To Market pressure and I am
sure everyone (not excluding Ruud) gets more satisfaction from doing
something complex, which nobody did before.
