Tektronix 4641 Printer (DEC LA-180)

Hi, all, A friend of mine has dug the following item out of his basement. It is a free-standing dot-matrix printer, with a 'stand', which has power supply and (lots of TTL) logic in it. It is a wide-carriage printer with pin-feed, with single dot-matrix printhead. It has a label on the front that says Tektronix 4641, but inside the bottom of the chassis is a sheet that says "Digital Equipment Corporation" and "DEC LA 180". Sounds like Tektronix may have OEM'd this printer from DEC. It appears to have a serial RS-232 interface that is a separate circuit board that is 'added on' to some kind of parallel interface. Anyone know anything about this beast? Is it something that would be worth rescuing? Thanks, all. Rick Bensene The Old Calculators Web Museum http://www.geocities.com/oldcalculators
