I am in the process of broadening my understanding of the process of
hardware design and implementation by designing and building a coprocessor
for my Apple II+ with the following characteristics

	68008 at 8 mhz with one wait state
	32K EPROM
	128K CMOS DRAM
	RS-232 serial port with modem control
	Communication with 6502 or other coprocessors strictly
		through a pair of 512x8 high-speed FIFOs

I am well along in my own educational design right now and am part way
through assembling my prototype.  I have no immediate commercial plans.
My interest in other 68008 co-processors has increased during this
process, however.

I would appreciate it if anyone could provide details or pointers to
the sources of details for other 68008 co-processors.  I am especially
curious about the "DTACK Grounded" one, which has such a charming name.

Please mail replies to me.  If sufficient interest is indicated I will
post a summary to the net.  Thank you for your time.
