By coincidence, today I started evaluation of a punched/optical card reader. Model TM200, made by Documation Inc.
Naturally I have zero information on it so far. Does anyone know where I'd find a service manual or schematics? Pics here: http://everist.org/pics/TM200/ It will get a writeup at http://everist.org/NobLog/ if it seems to be a feasible restoration. The immediately obvious problems: * Mains input connector is one of those old round locking type. Not sure if I have any of these. * Hose from vacuum pump to pickup heel is hardened. Needs replacement. * Plastic elbow fitting for vacuum to pickup heel is broken in half. Make new one. * Plastic mount for status display lights is cracking around brass nut inserts. * Four rubber transport rollers have de-vulcanised, melted, and flowed gunk. Urrgh, what a mess. * Ouch, that interface connector. I wonder where I'm going to find some card stacks for testing it? If I get that far.
