It aint that someone would by 72 pin, it's that it would be
recycled from even more obsolete or fried motherboards.

The slot issue is that the design should have slots for any
card that might be found in a donated machine that might
still be useful.

The original IBM designation for the two 6 pin power jacks in a
standard PC motherboard, recently being phased out by a
single 20 pin Molex in the ATX configuration.

I've used the 503; it is a damn good board, and has most of what
is needed, except the ability to run a low power Carosoe chip.

If it runs the Carusoe, it dont need a slot edge and the blower
that comes with it. And if it's ZIF, then the poor guy
in the boodocks dont worry about whether he cracked the mthbd
trying to stick in a new CPU, and he dont worry about a bent pin.

I cant say that any of them are, or ever were. I've used
the Cyrix 166, and run it with _passive_ heat sink arrays,
about 4 times that on a 486. did all right.
the 266 are prolly ready to have the price down where I
bother with checking them out. havta try it. thanx.
no copywrite. do what you will with this.
