	Yes, but realise that these lines are not in any way connected to the
Amiga bus. You need some sort of 'dumb' bridge board to access them.

:know in advance.

	What you'll want to do is design a simple bridge that lets you access
the ISA slots via an Amiga autoconfig board. Then you can access any PC type
peripherals you want, by simply mapping them into the Amiga space and writing
a device driver or two... :-)

:IBM???  Are they AMIGA-compatible???

	Commercial plug time... :-)
	
	NES, Inc. makes a prototyping board specifically designed for this type
of project. Our AM-200A board has both the Zorro II/III connector and the ISA
connector. It also has a fairly decent ground and power plane, with a couple of
15x15 grids for PLCC or PGA packages. Retail price is $49.95 and can be bought
through better Amiga dealers or direct from our marketing people. Call Software
Technology, Inc. at (503) 653-2090 or write 10610 SE McLoughlin Blvd., Portland
Oregon 97222. I don't know what they change for shipping, but I'm sure Randy
or Bill could tell you. :-)
