Has anybody ever seen a special Tymshare model ASR-33? It's more or less a standard ASR-33, except that it has a three button CCU and the silver plate on the front (the one which would ordinarily have the Teletype name and logo) is painted blue (DECsystem-10 blue, I would imagine!) and lettered "Tymshare | Time Sharing Terminal." The CCU has three rectangular buttons marked "COMP", "LCL" and "OFF". Any data on what this CCU does? I'd like to modify the ASR for DEC compatible service (which should be easy enough), but I'd like to keep as much of this CCU as I can. It also doesn't have the reader power supply that's usually clipped on inside the pedestal, so I'd guess that it's part of the CCU. Another reason to keep the CCU if I can. Oh - and it also has the cutest little 4W fluorescent tube inside the paper cover to illuminate the printout. There's a ballast and a standard glow type starter inside the CCU. Thanks, Bob Armstrong
