Kyle, always good to hear from you. About the size and depth of your 
post, I'll comment but frankly policy is up to the listserv moderator 
Evan not me. My own comment is: content preservation and distribution is 
best served thru a Web site, not an email list. That's my 20th century 
point of view which I do not apologize for.

That aside, you've shown good work to deconstruct the Fabritek 
implementation of the PDP-8. Your description needs no further comment, 
um, that's a good thing. ;)

Neil Cherry and I had the pleasure to work with Connor at the event, on 
his Fabritek, which is not able to read from his reader. We with Conner, 
based on oscilloscope readings, determined the reader was getting serial 
clock and data/control bits, but not returning any data. But the reader 
was responding to IOT's out to the reader to display octal values or 
operate the reader. This suggests serial output from the reader is a 
good place to start looking.

Kyle (and Connor), contact me privately about more information on the 
Fabritek, in the usual way.
