I don't know if it works on these instruments, but there was an interface to
use a quadrature mouse on an HP-HIL system.

As somebody who has both and uses them (and has no later analysers), I have
to disagree with you there. After all the OP was asking for the 'Tek 465 of logic
analysers' which suggests not the latest instruments. The HP1630 and Gould K100D
are easily fast enough for classic computer work (I've never had problems). They
also seem to be a lot better documented than later analysers (can you get 
schematics of later HPs? I seem to remember they are not in the manuals). The 
probe interface is also documented and quite simple. While I recomend only
getting a LA with the original pods, the ability to make custom pods has helped
me on several occasions. The inputs to both those LAs are simple differential 
ECL signals, easy to hack about with.
