Last night I was trying to figure out the interface on one of my teletypes (KSR-33). I was very frustrated by the Teletype manuals in that they don't (at least mine don't) talk about the various interface modules in any detail. Is there documentation on these beasts? Specifically how to hook them up to other equipment (like computers)? However in the process, I discovered that the particular teletype I was working on has the EIA RS232C interface. And no this wasn't some bodged together thing by some previous owner. It was all Teletype components. I was *really* blown away by this! To verify that this is what it was I hooked it up to a (sacrificial) RS-232 terminal and what was typed on one showed up on the other! It also verified that the teletype was indeed working. -- TTFN - Guy
