Zetron M4010 Info. Needed

[WB6DGN]

Do any of you LMR folks have schematics and/or module pinouts for the M4010
dispatch console?
Specifically, I have an ANI decoder board, #702-9583, from one of these consoles
and I need the pinout (and, preferably, schematic) for it so I can try to modify
it as a stand-alone MDC decoder.
I tried Zetron; they wouldn't give me the right time of day; and also tried web
search and came up empty.
Any and all information will help.
Geeezz! You'd think this thing was some sort of state secret or something!
MDC's only been around for over a decade! Email me direct or...?
My email is tallinson2 <at> yahoo <dot? com. Thanks,
