Thanx to Ben Greg and MadDog for the excellent keyboard cleaning instructions. Mine works fine now - I simply scraped off the oxidized browning from the black rubber rings and from the metal circuits on both mylar sheets lightly with a little swiss army knife (it took too long with an eraser - and I managed to break only one contact which I'll fix with the conducting glue tomorrow). Being able to fix stuff thanks to the grass-roots ethic of forums like this is an immense pleasure. Now I have a configuration query. This Duo 230 has System 7.5.1 installed, the same as I have on my slowly failing Powerbook 170. Since I'm not much of a tech-head, I can't understand why the the very same system on the PB170 takes up 2055K RAM, while on the Duo230 it takes up around 21014K, ten times as much! What is this down to? I tried turning off extensions (and virtual memory), but that's made no substantial difference. Since I haven't found a source for system 7.1 (not free from Apple, so not downloadable from anywhere...) which I was actually hoping to install (and since Dylan provided a convincing set-up for what I want to do using system 7.5) how can I get the system to eat less RAM? Could this be something to do with the fact that the Duo230 originally had 7.5 and was then upgraded to 7.5.1? Is there a way to downgrade/reinstall other than with the original system disks (which I don't have)?
