Zetron Model 38A Repeater Tone Panel Instruction Manual (#025-9043Y) (with scanned schematics)   1.17 MB PDF file   Donated by Eric Lemmon WB6FLY
The cable that plugs into the 38A is part number 709-7112 (and the price in fall 2006 was US$35). This is the generic cable with flying leads (as opposed to one that has a connector that is designed to plug into some other manufacturers equipment).
BTW the differences between a 38 and a 38A are changes to both firmware and circuitry. They are similar in function and name but internally they are essentially different products. It's not really practical to attempt a field upgrade.

Note that this manual is available in two forms:

Zetron, Simplexor, Worldpatch, Microconnect, Repeaterman, Europatch, Deadbolt and probably a few other terms are either service marks, trademarks, or some other legal mark and no infringement is intended. If Zetron had these files on their public web site we wouldn't need to.
