GNU followers don't want everything to be free - they want there to be a
free software alternative to everything. Which is entirely different.

Come come andrew, that's a cheap trick - taking words out of context.

If you don't believe that illegal copying is just like kidnaping and murder,

What i bet it doesnt say is, if you really want to enjoy this
machine - try and locate one on ebay :D Nothing beats the
real thing.
Actually I disagree. The emulator is now fast, accurate and featured enough
that it's far easier to code than using the sam ever was. Using Comet in
fast mode
Nahhh, your missing the point. I know the emulator is
basically perfect, but its just not like having the
real thing sitting there (I trust you have got the real
thing as the rom is still copyrighted and hence the
emulator is only legal to those with a sam).

works ok for me. It's not perfect, but it runs most things OK.
Things it doesn't manage generally run with Archie

Don't you need to buy a drive which supplies the RD (Ready) signal?

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?
Uhh. I dunno, I

Ok, my first post here in ages, here goes...
the official Z80 cycles rounded up to the next multiple of 4 (or 8 in
screen time), or, 4 (or 8) times the number of memory accesses;
whichever is greater.
Thanks! I vaguely remembered something like that but wasn't sure.
OK, so my memory isn't too hot. Given that this code will probably execute
in screen time, is it quicker to do:
LD A, (HL) = 7 cycles
AND EE = 7 cycles
LD (HL), A = 7 cycles
or
RES 0, (HL) = 15 cycles
RES 4, (HL) = 15 cycles
NB The cycles here are raw z80 figures.
Obviously on first glance

Note: I should have written
AND C - 4 cycles
since the EE is preloaded to a register (ostensible to increase speed).
