The April Advertisement of the Month comes from the February 15, 1962 issue of Electronic Design. To complement the February Photo of the Month where Lucille Ball was intimidated by a computer incorporating a Tek RM35A/45A oscilloscope, we present an advertisement titled “Wide Choice of Tektronix Oscilloscopes for Rack or Console Applications”, It summarizes the 11 oscilloscopes that made up Tek’s 19-inch rack mount line at the time. At the high end priced at $1,650 ($17,900 in 2026 dollars), the plugin-capable RM45A is featured at 30 MHz. The bandwidth for the RM503 and RM504 is 450 KHz. Both depictions of the RM45A show the Type L plugin. Mounted above the RM45A in the lower left corner is a Type 127 Preamplifier Power supply with a Type CA and Type L plug-in.
