Where have all the Selectrics gone?

IBM made a bunch of printer terminals based around the Selectric typewriter - 1052, 2740, 2970 etc. Look in any old copy of BYTE, and you'll also find several vendors were selling 3rd party terminals based around IBM Selectrics, often converted for ASCII/RS-232c operation, as teletype alternatives. Where have they all gone? (I appreciate, from what I've heard, that many folks who used them in anger would reply 'I don't know, I don't care, good riddance!') Early DECwriters are not uncommon. Teletypes are (almost) ten a penny, ASR33s show up frequently enough on ebay, I have several. But the only Selectric based unit I've *seen* in over ten years of collecting is a 2970 Reservation Termainal (see http://www.corestore.org/2970-1.jpg ) which I was offered a year or so ago. It needs a fair bit of TLC, and it's a print-only device; it can receive data from a host and print it, but not send anything back from the keyboard. I'd love to get a bidirectional equivalent to use as an 'authentic' terminal for a 360 emulator I work with... any clues? Can anyone recommend a Selectric repair shop? No way I want to try to fettle something THIS mechanically-intimidating myself! Mike http://www.corestore.org
