Side slot label says "ROM PACK Use only with 1200RXX Series" Rear slot label says "COMM PACK Use only with 1200CXX Series" There are two cartridge interfaces. Rear slot is for I/O devices; three were produced. 1200C01 is the RS232C Comm pack. on way 1200C02 is the GPIB comm pack. on way 1200C11 is the parallel printer comm pack. Requires the 12RC01 Printer Support ROM pack. Side slot cartridge interface was memory specific and was for ROM and RAM packs. Both 8K and 64K RAM packs with battery backup were made. ROM packs series 12RMXX 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. 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 SuperPack 1.0 designed by Pavel Korensky. A multifunction RAM/ROM cartridge for the 1240/1241.
