I’ve checked some PDP-8 software and found WHATAMI. That checks what PDP hardware someone has.
/10=KK8F [PDP-8/E, F, M, 8A-600 SERIES].
/11=KK8A [PDP-8/A 400 OR SIMILAR].
/12=6100 CHIP [VT78 OR INTERCEPT I].
/13=6120 CHIP [CPU8 OR GIZMO].
As I have an Intersil 6100 on my Festo device, I found the Intercept I. Searching for that, I found this German Retro site with some good photos of an Intersil Intercept Jr. (another computer) and a description on how to print out a papertape with ASCII text.
There’s also code and some special memory mapping of the Intersil.

The punchtxt software is from here and has a list of characters like A= 254;9;9;9;254 (all 5 bytes)
Intercept I and II are another trainers. I haven’t found any photo and few info about that.
Next to the Intersil Intercept Jr. And Intercept II/III there was also an Intersil Concept-48 with 8048 code. (Also some other board there)

I found some details/manuals for both Intercept and Concept (next to all other ICs) on the 1981 Intersil Databook (1230 pages). Intercept II page 1138, Concept on page 1147
Intercept III I mentioned here
I found this website some years ago, before purchasing my Festo device. Recently I stumbled again on this link. In the 6100 PDFs there are poor b&w photos of an Intercept Jr and/or Intercept I/II but I think I never found an Intercept III. And I think I never found this by a Google search.
Next to the great photo there are also some (new) PDF manuals on the left. The Intercept III has a control panel although the chip works without one.
