Now that I have a slightly positive cash flow, I'm seriously considering
putting together a computer system of my own to experiment and hack on. It's
going to be 68000 based: that's what I use at work, so I know it quite well.
Currently, I am thinking of:

	Compupro CPU-68K processor board ($565)
	Lexicomp SR-64K 64K 8/16 bit wide memory ($300)
	U.S. Micro S-100 Mod motherboard/cage/power supply/enclosure ($395)
	Suitable bus termination
	Some serial I/O board.

You'll note that there's no disk or controller: for the moment, I can use
cross compilers etc. on a Vax and download. Slow, but useable for my needs.
When my budget recovers enough, I can start thinking about disks and
operating systems.

So my questions to everybody out there are: Are there any hidden gotcha's in
what I've chosen? Any comments, pro or con, on the products? Will I have any
problems later when I add disk controllers? Better prices on any of this?
Other boards I should be thinking of?

Also, what is a good serial IO board? I don't need anything fancy, just four
vanilla RS-232C ports would be fine. All the boards I've looked at have
frills I don't want (ROM, clocks, parallel IO, etc), and seem ridiculously
overpriced...

Thanks very much for any help you can give me!
