The Tektronix TM501 is a single-bay mainframe for the TM500 system. On the TM501A, the power switch has been moved to the rear.
Option 2 adds internal pin headers for the slot as well as a rear 50-pin and BNC connector, allowing for custom wiring to and from the plugin.
On the standard TM501, cutouts for the 50-pin and BNC socket have been made in the rear frame, meaning that the user only needs to drill holes in the rear cover plate to install the sockets.
