040-0803-00
The Tektronix 040-0803-00 is a mechanical kit to make a single-bay plug-in for TM500-series mainframes.
The kit includes a printed circuit board that interfaces with the mainframe and has free space for the end-user to build custom circuitry. Otherwise similar to the 040-0652-03, the 0803's board contains a pre-built power supply circuit.
