> >Funny. My first project after leaving university was a credit card terminal. It was built around a Motorola 6809 and used OS/9. Great stuff. I have written a lot of assembler for the 68xx series. Before that the 6502 was my baby. I really liked that processor. Which one? I don't remember a 6809 based system. >You must have been very visionary to forsee the use of that amount of memory. I would't. It was a time when the debugger, editor and assembler shared 8K of RAM. I had a bios for my system, that included multi-initiator, arbitrating SCSI, all in 8k. >I must admit that when the first C development tools came for uP's I was strongly against them. Taking to much resources as I saw it. Was an assembler Guru after all... ;-) But *wrong* I was and have learnt something from it. The first experiments we did with C were extremely dissapointing. Triple the code space, quadruple the ram, and execution time was rather sluggish. And this was with some pretty sharp guys writing the code. I'm still not using C much. It's faster to develop in of course, but it just can't keep up with hand coded assembler for economy or speed. _______________________________________________ http://www.piclist.com View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
