After much agonizing experimentation, we were able to successfully
connect an IBM-AT compatible (Compaq) to the Apple L/W with the
following pin configuration:

	Compaq          L/W

	1               8
	2               2
	3               3
	4              20
	5               7
	6               6
	7               4
	8               5
	9               None

Notes: Compaq had 9 pin serial port, L/W had 25 pin.
       L/W must be shut down when changing the 4 position
	switch on the back of the L/W from PS to ascii.

Hope this is of some assistance.
