There have been commercial multitasking/multiuer systems around for years on machines less powerful. PDP-8s had TSE which supported 16 users on a machine certainly less than 1/10th the speed. I wrote a successful multitasking application on a Z80, and even implemented a multiuser multitasking (multiple tasks per user) Forth environment on a Z80 (3 users). If you need at least a 386 for multitasking, your tasks are too big! Tom Almy toma@tekgvs.labs.tek.com Standard Disclaimers Apply
