There's actually a TurboMON-style mock-up in SimCoupé 0.82a - press '/'
on the numeric keypad to show a quick code/register dump at the end of

fortunately!

I'm happy to believe this - also I tried it on my machine at home and it was
actually worse so I figure it has to be a SimCoupe problem.

How d'ya manage that? I'd definitely be interested in using that rate
myself if possible, as even a smooth 100Hz still suffers from ghosting.
I didn't think modern monitors were happy running at such a low rate
though?
IMO yes, definitely, if you want to

I don't remember ever seeing drivers that supported below 60Hz :-/ I'll
have to see if my GeForce2 card will let me roll my own mode to support
it. My Mitsubishi monitor at

Thanks! I vaguely remembered something like that but wasn't sure.

It can be difficult to synchronise an interrupt routine exactly when the CPU
is busy in the foreground - when the interrupt occurs the CPU has to finish
the current instruction first. Could this explain it in your case? It's
