This is somewhat off topic, but I think many programmers would be interested to look at a working model of a microcoded computer at:
tomspages.com click on the link for 'Hack the Com puter Model.' It conveys among other things the physical events that underlie execution of a microcode instruction and, by extension, of machine language. I would like very much to get people's feedback on the thing. Thanks, tom arnall north spit, ca usa -- http://mail.python.org/mailman/listinfo/python-list
