Ok folks, I know that this is not what Martin was talking about when he made
the above statement, but when I read it, I just couldn't help but remember all
the times people have had queries about swapping SIMMS between macs and PCs.

Seems you sometimes can't put a Mac's SIMMS in a PC because the SIMMS that
Apple ships with their equipment are only 8 bit and don't support parity :-)

Isn't that a bit like wearing only one boot when you go to play in the snow?

At least ONE foot won't get wet! :-)
