Hi Tim and all,

Didn't Motorola make a 1-bit cmos microcomputer? Cannot remember it's part
number. I remember Turning machine articles in various places. One is "The
Armchair Universe" by A.K. Dewdney. It is a collection of "Computer
Recreations from the pages of Scientific American Magazine".

Do you recommend any texts that did a neat state machine computer with a EPROM?
This sounds like fun, but would like to see some examples of what people
actually did first to help start a design.
