- I bought it from a friend who is a serious 3B2 HACK (in the biggest way).
- He had 2 complete 14 Mhz chipsets and he sold me one. I have no idea
- where he got them.

- You mean the clock? There are two clocks, the CPU clock and the time
- of day clock.

- Yes, the chips get quite hot running at 14 Mhz. Actually, I have
- a fan blowing into my 400 to make sure it keeps cool.
-
- Speaking of this stuff, did everyone see the recent posting
- in misc.forsale.computer of several 14 Mhz 3B2's?
