I was looking for utilities, on the mac side, to overcome the keyboard problem.
One could be visualkeyboard 1.2 (take it from http://hyperarchive.lcs.mit.edu/HyperArchive/Archive/gui/visual-keyboard-12.hqx ) which gives a customizable onscreen keyboard. Beware that when I opened its configurator, basilisk crashed, trashing its virtual hd, which I had to recreate.
Maybe also ResEdit could be useful.
