This is just a (somewhat belated) note of thanks to Sheldon for
posting the information on the use of 6-level and 5-level
equipment at AP.  Thanks!  It is especially nice to
confirm that 5-level equipment continued in use alongside TTS.
In 1978 6-level circuits could have been driving either Linotypes or any
of a number of phototypesetting machines (e.g., Linofilm) or standalone 
composing computers (e.g. Compugraphics Justape).

Regards,
David M.
