	yep, lots of them... for used, and 18-bit, about 600.

		likely the same answer as above....

	The lsi-11 bus IS the q-bus (or at least the 16-18bit version of
it... the current Q-bus is 22-bit using some lines which were originally
called [reserved for 22 bits] but where used for diagnostics on several
boards.  I have the most current list of which boards are 22-bit capable 
and which are only 18-bit capable.

	Ah, but what a skateboard

	My memory of 8's is way too faint, but I do remember the ][+ and
the original ][ and I still use LOTS of 11's
