ASR-33 (was Re: Shame, shame, shame)

Tony writes: Speaking of ASR-33's, I've got one in storage that's a bit under the weather. Originally, it must have belonged to a newspaper or news service - it does not have a 20mA interface, it's got a 110 baud modem (data set) built into the pedestal, the *whole* pedestal. What's wrong with it is that many years ago, when I was much younger and much more reckless, I removed the touch tone keypad and do not have a diagram for putting one back. As it stands, I can call into it, but I can't call out of it (if plugged in, it will start up when the phone rings and turn off when a CTRL-D (a *real* End Of Text!) goes through. At one point, I was going to remove the data set and attempt to hack back in the current loop. Now, since I have a phone line simulator (8049 uP- based product of a former employer), I can rig up a current loop to RS-232 converter (got one) to a 300 baud modem, route through the C.O. simulator and "dial up" the TTY. All this, just to get a teletype on a PDP-8. Somewhere in storage, I have mechanicals on the ASR-33 itself, but not on the data set mod, especially not the keypad. Does anyone out there have any info on Western Electric touch tone keypads? ISTR that this one had more wires than a typical phone keypad of its day, say 12 instead of 8, but that is only a guess.
