Hi Fred,

I am trying to get a head start on my miniboard project while I wait on
Greg Ratcliff's boards and Dave Dunfield's C compiler to get here.

I have two Motorola M68HC11EVBU boards that have 68HC11E9 chips.  I can
get PCBUG11 to work with them if I disable the onboard BUFFALO ROM and
reset into Bootstrap Mode.  I have been trying to get DL, MON and IC to
work with the EVBU with no success.  I assume that this has to do with
the serial line echo weirdness mentioned above?

Are there configuration mods to your programs to disable the
requirement for echo?  Do I need to re-compile the programs?  Do the E9
parts have the right amount of RAM/EEPROM for this to work at all?

Will the miniboard work with any of the 52 pin FN parts?  I have
several of the 12K MC68HC711E9 chips.  (Assuming I can program them)

Thanks for the work so far.  (Neat schematic!)
