If anyone cares, I've been working on a Pertec tape controller design.
The initial version worked remarkably well with only a few bodge wires.
I'm assembling the respin of the design and do not anticipate any issues.
I'm guessing this is a formatted Pertec interface. My CDC
Keystone drives have that, and I hacked up one of my CNC
control cards to make a read-only interface that
communicates at modest speed over the PC parallel port.
(These choices were not optimal, but reused infrastructure I
already knew well.)
MANY years ago, I got a surplus 800 BPI 9-track key to tape
system and hacked into it to put 9-track tape on my Z-80
CP/M system. That was a fascinating project.
