Sargon Pathfinder DRO system



I have a chance to purchase a 3 axis Sargon Pathfinder for (asking) $300.
There is a problem with the Y encoder, however being 18" long (I need about
12max), I would have to replace that anyway. The other encoders are the
correct size and in good working order.

It is possible I can repair the encoder reader unit since it appears the
wires have been pulled.

First; what is the reputation of these Pathfinders (circa '90s)? What
features do or don't they offer? Is there a site where I can look at the
manual?

I know that the encoders are the glass type. Could I interchange most any of
the common encoders, I see on eBay?

Can a glass encoder be cut down in length?? Never seen that proposition
discussed here.

Looking forward to comments and experiences.

Steve
