"Is Al serious about his Cinematronics to Asteroids monitor converter?
If so, I hadn't realized how much progress had been made while I was on
sabatical."

Clay and I are quite serious. I started poking at the design about two
months ago (just before I got sucked into the time sink of 70's B&W
raster games, but that's my own fault..) and I'm really interested
now that two different designs on PC boards were given to me.

I just looked at the schematics, and it turns out the design that used
DAC80's used a 4016 analog switch instead of the National LF part.
I'll have to trace out the other design that used National DAC1221's
and an LF switch.
