Thanks for these pinouts ..
you need exactly this mouse (e.g. as an object in your collection in
its owen right), or are you repairing a machine that
uses it? In the
latter case, just about any TTL-level quadrature mouse will work.
I would like to have an orignal Depraz, since I hope to reconstruct a
second Lilith from the spare parts I have : I only have to reconstruct
the display card, I have a spare for all the others. And I would need to
make a backplane. Since it is mechanically compatible with the dec
Omnibus / Qbus backplane it should be feasible : I have a spare QBUS
backplane and 2 Omnibus experimenter boards.
I realize any ball-type mouse could easily be converted to quadrature
output, but only the orignal Depraz is the "right" match for a Lilith.
Incidentally, if you have the mouse and it doesn't
work, I do have
schematics (not that it's hard to trace them out!).
Probably not, but tracing out the rest of the Lilith is another matter.
But I am 80% through !
