Betreff: Re: Squeak on Compaq TC1000 tablet
Thanks Tim --
I've been playing with it as well. Andreas gave me a tip, which helps a
lot with using the pen for drawing in Squeak: set the "High
Performance" preference to on. The TC1000 has a bug in how it gets pen
points which shows up in both its SW and in Squeak. With the preference
"on" Squeak seems to do just as well with points (which is still a bit
laggy) as does the MS software.

Done by guess who? Chuck Thacker who did the original Alto at Xerox
PARC. Another "grey haired old guy who won't give up".

It does run well -- and could run even better if we did a TransMeta
emulator for the bytecodes. Also, the Croquet stuff runs surprisingly
well on it, given that it doesn't have the biggest and best graphics

Yeah, but it's nice to have to do penbased experiments for the future,
etc. We've (Yoshiki) has also put Squeak on the Fujitsu 2.2 penbased
lightweight (runs really well) and is in the process of doing the new
Japan only Zaurus PDA (pen based with a beautiful tiny full VGA color
