Probably NOT. In keeping with Mark Schrier's overclocking habits, I'm guessing someone resoldered a faster can into it. I've done it with my Mac Plus, cranking it up to a brutal 10Mhz., and a LC II which just repeatedly crashed. As an aside, the Plus's beep tones were all higher pitched and the display shrunk by about a third and had to be readjusted. BUT!!! I had an accelerated Plus! In fact it may still be around here somewhere....... Jeff G -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
