I usually just use 12MHz. A whole lot easier to find, and I doubt
anyone could tell the difference in speed.

I have these, but I charge $2.50 a pop for 'em. They can be had from
Hamilton Hallmark (or was it Arrow?) for $1.25 each plus shipping and
minimums.

Rare. I usually just look on old PCB's and get lucky once in a while
finding one... Should probably make a replacement for these... I think
Centipede and Millipede might have used them as well.

Huh. What's it off of? A 4015 is a CMOS shift register or something I
think. Maybe it's a 2015 or 2115 equivalent?

JDR should have those for about $4 a pop plus shipping. I've got a
bunch of CMOS ones for $5 each. (Tested on Space Duel-- work fine)
