It supports all of the Intellec devices. What you can do depends on what hardware and software you get. But a few of the things that it does are: Burn EPROMS, supports Assembly langauge programming (for LOTs of CPUs), Fortran, Pl/M, BASIC, COBOL, hardware developemnt including In-Circuit-Emulators (ICE) for most or all of the Intel CPUs (maybe others too, I'm not sure). Don't discount these systems, they may be old be they're very powerful and are still in use today. They can develope, simulate, test and burn in programs for things like the 8049 and 8051 dedicated uProcessors along with all the standard Intel CPUs like the 8080, 8085, 8086, 80186, 80286 etc. I don't know if these supportted the 80386 or 80486 or the newer CPUs however. This would be a great machine for those guys (and gals, Allison) that still like to tinker with the Altairs and SWTPC and the other old machines that are based on Intel CPUs or will run Intel code like the Z-80 does.
