MacUser, January 1990 discussed re-wiring a modem cable for use
with high speed modems.  Included in that article is a shematic
of the changes needed to adapt the current cable.  Use this as a 
guide for making your modem cable.  They say you can still use 
the adapted cable with a slow modem.  Words to the effect of the
schem:

DIN 8 pin number			25 pin D pin number
	1					20
	2					5
	3					2	
	4					7
	5					3

The adaptation for high-speed modems, cut the 1 to 20 wire, replace
with a 1 to 4 wire.  Enjoy...
P.S.  I just purchased a modem cable with 8 pin DIN connector, plugged
it into my 9 pin DIN connector on a Mac Plus.  It works so far (10
minutes or so).  Anyone know of any problems related to this 
arrangement?
