I think the oscillator said 32mhz on it. I will double check it tomorrow.
The board seems to work. It takes a long time to boot up since it is
looking for my Appletalk network which is not up right now.

I figured it might be a 7mhz upgrade. There are four chips installed
for the cache so I would assume that it is the 16k version. How might
I find the 64k cache chips? They look unusually large for RAM chips.

Thanks. I will print it out tonight and look it over. Hopefully it will
clear up a few things for me.
