I just looked at the TC02 and the Qualstar, there are termination

chips near the J1 and J2 connectors.
This is where the electrical engineer could help. How do you determine
how long a cable the 74LS240 can drive?
TC02? The DECtape controller?
Sorry, I must be dense; I'm not following.

The TC02 is an Emulex TS11 emulation for pertec interface tape drives.
The J1 and J2 are sort of standard terminology, don't know why.
