	The kits are $57 and $75 respectively from distributors, if you know
	of one to talk to.  I picked up one 32016 and a pair of 32032 kits at
	that price.

	caveats:
		All the parts in the kits are 6Mhz parts, at least 10Mhz
		32016 parts are available... I was disappointed, but not
		surprised... should be plenty fast enough for you to have
		fun playing with.  I figure that with lots of DMA for I/O,
		it should go fast enough for my target prototype as well...

		The Tiny Development System stuff seems to want com ports
		based on 8251A USARTS.  I guess this is ok, but would have
		been MUCH nicer if they added hooks for custom I/O routines.
		For what I'm doing, Z8530's are so much nicer.

		Think about what, if any, software you will have to run on
		the box when you're done.  I have a Symmetric 375, and so
		have a full BSD C compiler/assembler/linker that should be
		easy to use generating ROM-able code for my target(s).  Not
		sure what else is available, as I've never looked.  As much
		as I like the 32XXX family, the 68XXX family at least has
		CP/M 68K and OS9 available... think about it.

The bottom line?  If you want to get into 32XXX hardware, the kits are neat.
They come with loads of docs, plus a listing of a turbo-pascal program for a
PC that will talk to TDS for uploading/downloading code from a PC.  6Mhz parts
are a drag though.  If you are not a 32XXX fan but are just looking to get in
to this level of hardware, look at 68XXX stuff.  A simple single board with
68000 8-10Mhz, a couple serial ports, disk, and a bunch of memory makes a
VERY nice OS9 box...  Software is THE issue.
