Then I heard that the price went to $168.00. You get the board and a couple of books. Moto has a bulletin board where they give away a free assembler (with C source code) for the chip. As far as a DOS based development system, all you really need is a serial port and a loader program which I can post if there's interest. The 6811 I've dealt with is the MC68HC11FN1 which comes in a 52 pin square J lead package, sockets are available. I think Moto makes the chip in other packages as well.

I'm sorta playing around with the idea for a MIDI/CV-gate convertor. Problem is, they're a pain to program !!! However, they're very cheap.

There's numerous ideas for applications for this, my favorite being to trigger off custom sound circuits that you can breadboard really easily.
