Had to do a lot of (6502-like) LDA ABS,X , where the X register was very variable. On the 6809 had to do a lot of ABX stuff to accomplish the same. Maybe I was stupid…chose the 6809 on general recomendation to do a particular app that it turned out was inapropriate. Took a look recently at the 6809 book. For many stand-alone things the 6809 is really handy (being able to change Page Zero is nice), But for the app I was doing, the 6809 was slower (fetching prebyte/postbytes) and missed a needed address mode. Thew fact that I hated the application that I contracted to do might have colered my view, but I could have done it on a fast 6500/11. After looking at a 6809 book recently, I must admit, that for certain systems (rather than applications) the 6809 is the preferred machine. *kevin* Enter command, N for next message or <CR> for menu : n
