There are some differences between versions of the 6845, depending on whether the machines they were 'intended' for (ie. what that particular manufacturer had in mind) had seperate READ# and WRITE# lines (as on the Z80) or a single R/W# line (6502). The Amstrad CPC sites have details on this, referring to them as CRTCs of version 0, 1 or 2. Richard - This message was sent through the cbm-hackers mailing list.
