Exchangeable ROM cartridges allow for mnemonic disassembly and state analysis of most microprocessors of the time.
There are two cartridge interfaces.  One 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 other cartridge interface 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 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.


An optional "Comm Pack" provides a serial port including remote control capabilities.
There is a design for a multipurpose RAM/ROM pack, called SuperPack by Pavel Korensky, note the errata in the readme:  [[File:Tek1240-SPDesign10.ZIP]]

The CPU board has battery backed up RAM to save the current configuration and one user config.  This battery is a potassium hydroxide electrolyte cell.  It will eventually fail and leak, damaging the PCB.  The battery is visible on the picture for the A09 processor board.
