The '''Tektronix 1240''' is a logic analyzer, introduced in 1984. The '''1241''' is the same device but with a color-shutter CRT, it was introduced in 1986. | The '''Tektronix 1240''' is a logic analyzer, introduced in 1984.

The rear slot is for I/O devices; three were produced. The [[1200C01]] is the RS232C Comm pack. The [[1200C02]] is the GPIB comm pack. The [[1200C11]] is the parallel printer comm pack. It required the [[12RC01]] Printer Support ROM pack. | |||
The cartridge slot interface on the side of the instrument was memory specific and was for ROM and RAM packs. Both 8K and 64K RAM packs with battery backup were made, note that the battery is a potential HazMat made by Catalyst Research and may destroy the cartridge when it leaks. There were also ROM packs (12RMXX series) that allow for mnemonic disassembly and state analysis of most microprocessors of the time. The ROM packs were made with a generic PCB that had two socketed ROMs and jumpers to select the size. | |||

The power supply is a switch-mode supply that mainly generates 5 V at up to 45 A. It requires a minimum load of 11.6 A. Additionally it generates 3 V at up to 8 A with no minimum load and several other voltages that are derived from linear post regulators. | A separate I/O processor board is powered by a [[Zilog Z-80]]A CPU.
