IMAX 432

iMAX 432 (forkortelse for Intel Multifunction Applications Executive for the Intel 432 Micromainframe) er et operativsystem som ble utviklet av Intel for datamaskiner med 32-biter mikroprosessoren Intel iAPX 432. Begrepet micromainframe ble brukt i markedsføringen for å beskrive ytelsen til iAPX 432 som sammenlignbar med en stormaskin (mainframe). iAPX 432 hadde en annen datamaskinarkitektur og var ikke kompatibel med Intel 8086 og etterfølgende mikroprosessorer som ble introdusert i IBM Personal Computer i 1981. iMAX 432 ble implementert i programmeringsspråket Ada; nærmere bestemt av en delmengde av den opprinnelige 1980-versjonen av dette språket, som var blitt utvidet med typesjekking under kjøretid og dynamisk pakkeskaping.

As of 1982 in iMAX version 2, iMAX was aimed at programmers rather than application users, and it did not provide a command line or other human interface. iMAX provided a runtime environment for the Ada programming language and other high-level languages, as well as an incomplete Ada compiler which was to be extended to cover the full Ada programming language in a later iMAX version after Version 2.

There were at least two versions of iMAX as of 1982, Version 1 and Version 2. Version 1 was undergoing internal Intel testing as of 1981 and was scheduled to be released in 1982. Version 2 was modular and the programmer could choose what parts of the iMAX operating system to load; there were two standard configurations of iMAX version 2 named "Full" and "Minimal", with the minimal configuration being similar to Version 1 of iMAX. As of 1982, a Version 3 of iMAX was planned for release, which was to add support for virtual memory.
