GW2K ColorBook (original not "CB2"):- Hotkeys? - CPU-upgrade?

Hi.
I have an ancient GW2K "ColorBook" 486 laptop to tinker with, but
little info on it...
Can anyone provide a list of the hotkeys for high/low clock-speed,
switching int/ext display, etc.

Also, could the CPU be upgraded - ie. Is it socketed? (Don't want to
disassemble just to find out...)
Currently it's an 486SX-33, so I'd hope a 5V DX2-66 would fit - but
don't know if 3.3V DX4-100 would be supported by the motherboard???

Oh, and I'm missing the piece of plastic on the front of the HDD-
caddy, if anyone has one to donate! :-)

TIA and regards - Mark.
