I obtained advance information about the Intel iAPX286 .... it looks very interesting.... also have some data on the iAPX 86/30 and 88/30 Operating system processors.... this looks extremely interesting, and one can assume that the 286 cannot be far behind in getting an operating system chip to go with it.... iAPX86/30 is a 2 chip processor, with 35 operating system processor primitives as instructions... things like job and task management, interrupt management, free memory management, intertask communication, intertask synchronization, and environmental control... It also supports 5 operating system data types: jobs, tasks, segments, mailboxes, and regions. Someday we'll be able to look back at the big RISC vs. CISC and wonder what all the fuss was about.... ... snip ... ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
