This project uses the 386EX with no BUS standard (ISA if you squint your
eyes and tilt your head just soo.  ;)  )

I can get away with calling the hard drive an ISA device (I'll have to add
afew more address decoding chips).  I'm not sure the EXs two onboard serial
ports qualify as an ISA device or attachment.  Could you take a look?

Here are docs for the processor I'm using the Intel386 EX 33MHz (Hopefully
I can get away with using 14.3138MHz).
