iMAX 432 (Intel Multifunction Applications eXecutive for the Intel 432 Micromainframe) was an operating system developed by Intel for digital electronic computers based on the 1980s Intel iAPX 432 32-bit microprocessor. The term micromainframe was an Intel marketing designation describing the iAPX 432 processor's capabilities as being comparable to a mainframe. The iAPX 432 processor and the iMAX 432 operating system were incompatible with the x86 architecture commonly found in personal computers. iMAX 432 was implemented in a subset of the original (1980) version of the Ada, extended with runtime type checking and dynamic package creation.
