It's kind of an odd architecture (by current standards). Well suited for assembler coding. The bit-addressable registers (including I/O ports) avoid the need to, e.g., do a read-re/set-write sequence to twiddle a single flag. The external memory interface isn't all that common on uCs and can be used to address memory-mapped I/O peripherals (external synchro-digital converters, for example). So, there's nothing intrinsically "wrong" with it, and it can be a very good fit for some projects. Just need to match the problem domain with the appropriate solution set. -- Rich Webb Norfolk, VA

Cheap and good. Excellent support. And the Imagecraft AVR compiler will work with the 8051? READ THE QUESTION BTW there is no better 8051 compiler than Keil -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

AFAIK there is no gcc for 8051 -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

SDCC yes, GCC, as far as I know, no.
