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'.

Unfortunately it has now been confirmed that Bill Green has died. I just received the following note in response to asking about Bill:

/Yep.. Bill is no longer with us.
I would be the only keeper of the grail...
However, I don't have one of those or the code./


So, now to find one of these machines that still works...right...
