> So when would I expect to see OS/LEIF out? been there, done that. OS/LEIF1 was called the RC4000, which Per Brinch Hansen and I wrote in 1967. In it we invented the process concept, message passing, the micro-kernel, event handling, etc. The S/38-AS/400 was a confused re-implementation of these ideas. OS/LEIF2 was a special-purpose OS for the Danish Weather Service main computer (1971). OS/LEIF3 was an OS for the Data General Nova to allow it to be used as what in the AS/400 is called an IOP (1974). OS/LEIF4 was a real-time OS to run a solar telescope at Stanford. Still in operation since 1976. OS/LEIF5 was a multitasking OS on the PC (1990) allowing it to run any number of DOS sessions concurrently. +--- | This is the MI Programmers Mailing List! | To submit a new message, send your mail to MI400@midrange.com. | To subscribe to this list send email to MI400-SUB@midrange.com. | To unsubscribe from this list send email to MI400-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: dr2@cssas400.com +---
