[TechAssist] Chipper check need schematic

My chipper checker stopped working. Does anyone know where to get a print of
the interface box? I opened it up and can find no 5V on the EPROM. I tested
the box with the chipper checker test and it comes up cannot find EPROM. I
need to know what is holding down the 5V. there is a diode by a transformer
that may be a zener but I don't want to fool around too much. Thanks. The 5V
coming through the interconnect cord from the adapter is there until I
connect it to the connector on the interface, then it drops to 1.3V. The box
fell off the desk and right after that stopped working. Can find no
cracks.Thanks.
