I'm going to be making a cable for so a friend of mine can connect his
Mac Plus to his PC/AT via RS232.  I got a cable pinout a while ago from
the store down the road (via Apple, dated 3/10/86), but I'm wondering
if there's a better cable floating around.  (This one doesn't do modem
handshaking correctly.)

Post responses directly to me and I'll summarize about a tested cable!

	Mini-8 Pin #	    DB25 Pin #
	------------	    ----------
	  (shield)		1		Protective Ground
	     4			7		Signal Ground
	     3			2		Transmit Data
	     5			3		Receive Data
	     2			5		DSR
	     1			20		DTR

Mini-8 pins are numbered:		On my cable:

	6 7 8			1 = red	     4 = yellow   7 = brown
       3 4 - 5			2 = white    5 = blue     8 = grey
	 1 2			3 = black    6 = green

Mini-8 to Mini-8 cables can be had for at most $30 from your friendly
neighborhood dealer, and ruthlessly cut in half.
