It ends up being around 790k because it includes several things that were not there in 1.2, and also, I have not spent any time being really careful about identifying unnecessary stuff in that image - YET. I know we could get back to 650k, and maybe less without a lot of trouble.

It should not be that hard to bring Blair McGlashen's 1.2 VM up to date for the Cassiopeia and HP machines. Then it would be nice to prepare for a couple of the new Jupiter machines as well.

It would be useful also to peruse the system and comment on what is of no use in a PDA, and what should be added, or at least not deleted.

Probably I'm just showing my ignorance here, but the above lines don't
execute in my Squeak 2.2 beta image on a Mac. I keep getting "unknown
selector" errors. (Actually, the second one did work.)
