OK, I'm just not familiar with 9-track drives in
the sense of who
manufactures the guts that everyone uses.
OEM drive mfgs
60's 70's 80's 90's

HP 7970 drives look a LOT like Kennedy 9100's
Lots of others primarily in mainframes (STC,
Telex,...)
Those two drives in the pics are fairly old incremental
transports.
