The Z-80 ran the floppy and, I think, the keyboard. The 8088 #ran everything else. Bzt... The 8088 ran all 16-bit applications (CP/M and MS-DOS.) It also controlled the video, keyboard, printer, and communications as well as any options modules (including the hard drive.) The Z80A was in charge of all 8-bit CP/M applications as well as control of the diskette drive. -- Steve (SPG6) spg@sunquest.com
