Does it mean, that you even don't put your Newton to sleep before changing
the speed? Maybe I am just too careful ...

Where can I buy dead PCMCIA cards? ;-) I don't want to use my working 32MB
just for the switch ... but I am not in a hurry so I'll look out for a dead
card. I am sure they can be found somewhere. The size of the switch is

Hm. It is nothing written on the box from what I have used. I'll need to ask
a friend who should know about it what I have used. Hopefully my Newton
doesn't get eaten away in the meantime!
