| John -- I understand you are using a GCC cross compiler for your 68000.  As 
| long as you are on a unix system, GCC is easy to configure as a 
| cross-compiler.  If there's interest, I can dust off my linux, get the sources 
| and build a compiler.  Actually, I'll go ahead and do that unless someone else 
| has done it or is doing it.  It'd be nice to have a DOS cross-compiler, 
| though, anyone know if there is one out there?

DJGPP is a DOS version of GCC (as I understand it). It may be possible to
build the cross-compiler with that. (???) IMHO, linux is the way to go; but
I'm a unix person and nearly pc illiterate :). There are other
cross-compilers out there but keep in mind that it take more than just a
compiler for good software development. With the GNU stuff, we also have
the assembler (GAS), the binary utilities, the debugger (gdb), and the
standard C library (glibc). I've used the m68k-sun-sunos4 target for
everything. I will be happy to throw in my "two cent" for anyone interested
in doing this.

| What is the chance of getting an etched version of your CPU board.  I hate 
| wire wrapping, but I'd be willing to pay a few dollars to get an etched board.
| I know getting small batches of PC boards is a FAQ on sci.electronics,I'll 
| have a look and see if I can get any info.  If anyone else here has 
| connections for getting etching done, please speak up.

6"x4" board with maybe 4 layers.... I could generate the complete layout, 
but I would rather spend the time working on the companion board if 
someone else could do that.  Let us know what you find in terms of cost.

I don't really want to start an endless CPU debate (and certainly 
not a "bye y'all" type flame war :):) ), but the development tools for
the 68XXX are here, free, and good. I ordered a 68HC811E2FN last week, and
will build the coactive gcc port for it; however, I don't believe the 
development environment will be as good. YMMV. (FYI: The 68k will be the
primary CPU for my EFI project, but I may use the 68hc11 under the hood to
minimize the number of wires running into the passenger compartment.)
