I heard from at least 3 different sources that Amiga UNIX and Amigados (and MSDOS) all run simultaniously on the Amiga. Well I know Amigados and MSDOS do, but UNIX? From reading the A500/A2000 Technical Reference Manual from CBM, it appears that the coprocessor slot has 2 modes of DMA operation. From what I understand, the standard 68000 AND coprocessor slot (like CBM's A2620 68020 card with MMU) can both MASTER the bus independently. In that case, UNIX could run side by side with Amigados, BOTH running at the same time. They could share the same hard disk controller, (or separate controllers). In the Zorro I expansion architecture, a coprocessor would effectively block the standard 68000 from being a bus master at all. But the Zorro II expansion allows BOTH to run to run at the same time. Am I dreaming or what. You can play games and run UNIX at the same time? Na, I must be dreaming. I'll go back to sleep. -- Work: Computer Consoles Inc.
