for those of you who have sent me mail about the EVB, I will give
you a quick run-down on it
's perks:

- RS-232 (422 compatible) terminal port, for debugging, etc.
- RS-232 host port, for real-time use, and for down/uploading code/data.
- built in monitor, assembler, debugger, etc. firmware.
- 9600 baud, max speed
- transparent mode, to connect host and terminal port (for single PC use)
- full HC11 pinout to edge-connector in-circuit evaluation.
- external ram/rom socket (where you could plug in your external ram chip
  which you could later transfer on-glove)
- and most importantly, $68!       

the 68HC11 has quite a few good qualities which seem to make it adequate
for powerglove interfaceing:

- 16 bit timer  
- COP watchdog timer
- Pulse accumulater - this could be real handy
- 2 mhz. clock speed (i believe that they even have one up to 4 mhz., now)
- 4-8 A/D's (8 bit)
- SCI, and SPI interfaces
- built in EEPROM, and RAM

for those concerncerned, Motorola also offers a contest, for students, on   
employing the EVB - to winner gets a Mac II and laserprinter.

                                                       
I hope to get a glove hooked up to the EVB sometime soon.  when I do, i will
post all my glue logic, schematic, etc.
