Can anyone identify the 14" HDD seen in the following photo (not mine)?
It's unusual in that there are two moving heads on the top surface of the

Speaking of BIG printers, does anyone have the maintenance manual for the
Centronics 101A impact printer?

Three possibly interesting papers about some Tennecomp equipment uses.
The third (MCA FOCAL) references the "PDP-9, PDP-9/L, or PDP-15".
Also references DEC-15-MR2B-D "Advanced Monitor Software System for
