YES, it is :-)

End of junk mail. Now for the real question:

I read in the latest issue of a music magazine (was it Keyboard?) that 
Dave Small (Gdgets by Small) has managed to implement Mac MIDI on the ST using
some additional hardware.

Using a similar method, could it be possible to emulate Mac II type colors etc
also on the ST?

Probably. Anything is possible, after all. With enough determination, you might
even figure out how to use the actual Mac NuBus cards in, say, a Mega ST. Then
you could shell out the $$$ for the actual Apple hardware, video card & monitor.
Or something.

So... On the 24 bit video card, is each pixel 24 bits, or do they just map some
number of colors into a smaller palette? (Or allow both?)

Perhaps a card that maps in somewhere between 4 & 12 meg, with up to 4 meg
of its own memory. At 24 bits/pixel you can cram a 1024x1024 image into 3 meg.
Make it use display lists, like the old GTIA. (Dunno, I guess you don't need
to mess around with lower & text resolutions when you've got 3-4 meg of display
RAM, eh?)

It would be totally incompatible with the regular ST modes, but no big deal.
CGA/EGA/VGA on the PCs is pretty hairy too, but folks still write code for them.
