I just received an interesting piece of late 80's technology. An in-circuit Digital IC tester (kit). Made by Alpha it is a Z80 based tester that clips over the IC in question and lets you know if it is working correctly. I suspect it is not unlike the Bug-Trap (HP) Logic Comparator. You need to key in the logic table for each IC that you wish to test (up to 24 pin), and it stores these in non-volatile RAM.
Seems to work and I shall post the manual, Eprom, and stored RAM (Dallas) eventually to TTL's FTP.

Ah, no, that would be 'easy' - the code was only in the battery backed up RAM. (background sound of person kicking self around the room) It also appears that Mr. Green may have died - am checking with another author who mentions a Bill Green from Radio-Electronics and Popular Electronics as the 'late Bill Green'.
