[comp.sys.mac.hardware] Mac keyboard echos 2-3 characters at a time

(NeXT readers, see paragraph 2, line 3.)

A Russian poet I know, who now lives in Boston, visited Moscow
recently and left his Mac 512 with friends.  (He's since bought a Mac
Classic.)  They had some misadventure: I think they plugged the Mac
into 220V by mistake and fried the power supply.  Someone over there
replaced the power supply with an IBM power supply, and now they've
got their transformer problem solved too.  Believe it or not, the Mac
still works, but the keyboard now echoes 2-3 copies of the same
character for every keystroke.

The poet asked me "what chip needs to be replaced?"  Someone in Moscow
told him he needed a particular chip related to the Mac keyboard.
Since I gave my brother my Mac and now own a NeXT (thank you NeXT for
the self-adapting power supply!), I don't know how to help the nearly
blind and impoverished but good poet help his friends.  Does anyone
have any advice?  Would replacing the keyboard solve the problem?

Please e-mail direct to geoff@bos.camex.com, since I don't ordinarily
read comp.sys.mac.hardware.  Many thanks!
