	Yes, I know- I was responding to subsequent information.  I had a
	SuperPET manual handy but not an 8096 manual.  I have since found my
	8096 manual, but someone has already posted the information you wanted
	so I will leave it at that...

	But that's what the SuperPET System Manual says- I was curious myself
	but neglected to hunt down a system and look before posting.  I don't
	see one either, so I must conclude the Motorola ACIA was deleted from
	the design.  I do not have any history files on the Waterloo board, so
	I cannot explain the discrepancy.  Sorry.

>> [...] I do know IEEE-Centronics interfaces are still available.
>Um, Fred, where?

	CBUG, in their latest news letter, lists a CBM-IEEE to Centronics
	adaptor board (6400 type) and connector changer.  The setup costs $50
	(US) plus $2 shipping.  I cannot swear it will work in your case but I
	can't see why it wouldn't.  CBUG, 4102 N.Odell, Noridge, Il., 60634 or
	call 312-456-8720 between 7PM and 11PM CST.

	An old Skyles catalog I have lists two IEEE to RS232 adaptors- one
	called SADI (expensive) and a cheaper one called TNW-1000.  A TNW-2000
	interface claimed to be bi-directional.

>Is there ANY 6502 mode support for the 6551?

	I have something called MTERM which does VT52/VT100 emulation.  I
	don't know if it's PD or not, nor do I recall how well it handled
	higher baud rates.  I used it to upload SEQ files to the VAX on rare
	occasions.  I should mention the SuperPET did support the 6551- a
	communication routine was accessed by giving the TALK command from the
	Waterloo microEditor. It could be configured for data rates up to 9600.
	Refering again to my old Skyles catalog, there are several terminal
	programs mentioned.  Perhaps they are still available.
