MC68306 Single Board Computer

16 MHz
2 MB Dram
Two serial ports
8 bit parallel port
Bus expansion connector

I run a modified eForth on this board.
The modifications don't conform to the eForth 1.x model because 
I've recoded the source using AS, a free, portable macro cross assembler: .
Assembly language CPU configuration code (12K).
Assembly language source eForth 2.1 (97K).

Here are the commands to produce the EPROM S-record:

asw -cpu 68000 -P -L forth306_rev21b.asm
p2hex forth306_rev21b.p -F Moto -M 3 +5 -r $-$
copy forth306_rev21b.hex infile.hex
srec infile.hex ffff 100000

SREC is a utility written in Turbo-C to relocate part of the memory
image into ROM space. SREC.C source code.  SREC.EXE 
Note that the input file name must be 8.3 format.

EPROM Motorola S3 file (65K .hex).
