- Understand I'm working at a disadvantage not having a strong familiarity
- with the architecture of the various parts. Within that context, I was
- wondering if one could get either an OTP or EPROM version of the chip
- that would work in the miniboard, using the existing miniboard tools
- but with the advantage that much of the C support functions would be
- pre-burned into the EPROM. Thus compiling in a call to the adc()
- function (or whatever its called to read the A/D controllers) would
- entail using only a small amount of EEPROM (to do the call) and the
- rest would be stored in the EPROM.
-
- The other thing I've noticed in my quest of 68HC11 info is that several
- people offer a "BASIC-11" system that can be installed into PROM versions
- of the part (no idea on the code size at the moment) and it might
- make a nice alternative version development environment "on-line"
- as it were. Or even a debugger that I could use to debug C programs
- downloaded into the EEPROM.
