    Well, since most computer collectors repair their own equipment, maybe I 
get lucky :)

    I need the operation/service manual of the DM501 (not A) digital 
multimeter from the TM500 series, from Tektronix. Maybe someone has a 
digital or paper copy :)

    Also, I need the 3842 DMM chip, used in many multimeters and my DM501 
that I'd love to repair. It is a kind of 7107 but very old. Mine is broken
