That is a LARGE collection of software. There was usually one plastic tray with just diagnostic programs. The PDP-8 was bootstrapped qith a 32 word program entered via the Front Panel Switches. This rudimentary program would load a paper tape, usually from a Teletype ASR-33 teleprinter. This...

PDP-8/M and PDP-8/F were OEM versions of the PDP-8/E. Virtually no difference except the capacity of the OMNIBUS backplane. PDP-8/I was NOT an OMNIBUS machine. It was built with wire wrapped backplane.

Amazing how many minicomputer architectures existed? Subtoutine calls were generally as described above or Branch and Link using a Register like IBM 360/370. Many DEC computers used the first word of a subroutine to store the return address. PDP-8,7,9, and 15.

I was thrown off by the term "optical". Linotype phototypesetting machines were marketed under the name Mergenthaler. Most Mergenthaler phototypesetting machines set type from six level TTS (Tele-Typesetter) coded paper tape. This same tape could also be used to operated tape operated Linotype...

I am NOT familiar with the ATEX hardware configurations. ATEX, in Bedford, MA used standard DEC machines and designed their own memory mapping hardware. They wrote their own software. Where DEC designed eight memor mapping registers, ATEX machines had 256 sets of eight memory mapping...

"Linotype optical typesetter" makes little sense as a phrase? The original Linotype phototypesetter was the Linofilm. It was a large system with proprietary keyboards and was used for typesetting display ads. The next product was the Linofilm Quick which utilized six level TTS coded paper tape...

ECRM scanner used a DEC PDP-8/M computer.

OCR A font produced on an IBM Selectric typewriter.

ECRM OCR scanners would read IBM Selectric typewriter documents. Using this scanner would require a newspaper to replace olf mechanical typewriters with more modern IBM Selectrics. Common and possibly only font read would have been OCR A?

Add PDP-15 to that list.

Likely that the "typesetting" machine was a mgd Metroset. MGD was a division of Rockwell Graphic Systems in Downers Grove, IL.
