Could be. They were showing a Z-21 on the SE-30 in NYC, though, as far as I
can recall. Also, the only difference between a Z-21 and a Z-21IQ (greyscale
model) is video RAM, which you can buy cheaply from a third party when you
decide you need it. It's getting cheaper every day.

No, I think at least three companies are close to done with a board to use
the apple tube with an SE-30. The only name that springs to mind is Irwin,
but I'd be surprised if SuperMac weren't doing one also.

>I read recently that grey scales refresh the screen much faster than color.

Absolutely false. Think about it. The computer has to do the same amount of
work moving bits around if you're using 8-bit greyscale or 8-bit color. With
either system, you can go down to 1-bit mode, and that's much faster.

You're in for even slower speed with an 8-bit large screen. Just remember
that you can always drop down to 1-bit mode.

Also, with the Z-21, there's no need to buy greyscale now. You can add it
later if you decide you need it, and you'll save money by waiting since RAM
prices keep dropping.

Yes. Spell "Guidance" with an "a". :-)
