> Of course in 1987 a Macintosh II with a fully expanded "Toby" framebuffer could not only do 256 colours, it could do it in 640x480 mode where as a PS/2's VGA could only do 16 colours at that resolution.

If cost is no issue, the PS/2 also had the 8514/A card that could do 256 colours at 1024x768. And there was also the PGC from 1984 that could do 256 colours at 640x480.

Hardly a party trick. Programs that used HAM weren't uncommon. It was an advertised feature, and there were even painting programs.

I guess you weren't there.
