Might or might not be the keyboard, but check that PSU in a IIci, 650, or 7100 if you have one around. They all used the same PSU. If that works, you know it's not the PSU, and is most likely the startup circuit on the mobo. Gamba has a schematic on his site that you might use to diagnose it. the pickle FAQ <http://macfaq.org/index.shtml> Software Archive <ftp://download:[EMAIL PROTECTED]//Users/thepickl/Sites/Archive/> <http://www.members.jmug.org/%7Ethepickl/archive/> _________________________________________________________________ -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
