I _guess_ Apple is getting old and conservative. Even the normal Macs only run
at about 6 Mhz because Apple didn't want to waste their money into video RAMs.

The worst problem with the Mac II was that the video card has to be in a NuBUS
slot. This means that the video memory has an access time of about 300 ns. You
can't get real time video with a 10 Mhz NuBUS.

The Mac IIx is a total cripple. The only reason to buy a IIx instead of a II
is if you want a superdrive.

The Mac IIcx is a winner. It's smaller than a Mac II, so I don't think it's
too bad that it doesn't run at 25 or 33 Mhz. They would have had to fix the
video problems, if they had increased the speed.

They could have created a 33 Mhz SE/030, but it would have sounded silly to
have the SE run faster than a II.

They should have designed a video slot for the cx. That way you could have
100-120 ns RAM for one video monitor and still have other monitors on NuBUS.
They could also have increased the clock rate, since you would have been able
to see the increase with the new video slot...

We'll probably see a super-expensive Mac IIxx within a year. I don't think a
lot of people will be able to afford it.

Maybe Apple should create a new family of computers. The marketing department
probably wouldn't want that, but it would be the right choice in the long run.
I don't want a Macintosh model designed to be a NeXT-killer. The Macintosh
architecture simply wasn't designed to kill NeXT.
