However, I don't want the list to be mislead too far by either the Intel or the Motorola partisans. > 1) Lots of PD assemblers, dissassemblers, simulators Motorola distributes a freeware assembler for the HC11 (and in fact, their entire 8-bit processor line) with source. It's nothing fancy, but it gets the job done. If you need a macro assembler, I can heartily recommend Matt Dillon's freeware DASM. I've used it for several projects targeted to the HC11 and the 6502. The PD MS-DOS program SIM68 does a good job of simulating an HC11. I don't have much use for it as I use an Amiga for all my development stuff (and find that I don't *usually* make mistakes that are easily solved with a simulator. :-) > 2) Reasonably priced pseudo-ICEs (approx $200) The HC11 was designed with cheap development tools in mind. Motorola's 68HC11 EVB will do pseudo-ICE of the single chip modes for $88.11. Expanded mode pseudo-ICE can be done with Motorola's EVM, or third-party products in the $300 range. Real ICE's are simpler due to a number of other features in the chip. > 3) Cheese-whiz Assembly code (includes such commands > as ANL and ORL, gotta love it!)

Motorola distributes a multitasking real-time executive (MCX) for the HC11, incidentally. Is there anything like this available for the Intel controllers? Just off the top of my head, here are a few reasons to prefer the HC11: fully static CMOS design, more orthagonal instruction set, cleaner bus, not Intel. :-/ > I am trying as fast as I can to whip up a MIDI box for the glove, > I want to map my MIDI drum machine to the joystick space as a start. > Hires mode makes LOTS of stuff possible, especially if you include > one of those NINTENDO twister board things (power-pad?) that you > can walk around on and use as an input device. Just mapping the glove to continuous controllers would interest a lot of my musician friends. There are so many possibilities of things to do with the glove that it's hard to come up with a single really concrete ones. Lemme know what you get working. > Forget the 68HC11, the 8051 is the industry workhorse for good reason. > Sorry if I'm stepping on any toes, but discourse is the soul of reason, > or something.
