There have been a few pinout question on the mac and mac+ like:


>I had my 128K Mac upgraded to a Mac+ yesterday.
>I noticed that the DB9 connector I was using
>for the modem had been changed to an 8 pin
>circular thing.
>
>Included with the upgrade package was a 6" long adaptor
>cable with a female DB9 at one end and a funny circular
>connector at the other.


Etc, etc etc......


Well here is what I came up with. Hope it helps.

Acording to "A+" june 1986 volumn 4 issue 6 on page 63 under the modem
column the pin outs for the personal modem are:

(This is for the mini din-8 connector)


	PIN#			Siginal Name
	1			Data Set Ready (DSR)
	2			Data Terminal Ready (DTR)
	3			Receive Data (RXD)
	4			Signal Ground (GRN)
	5			Transmit Data (TXD)
	6 			Siginal Ground (GND)
	7			Data Carrier Detect (DCD)
	8			Not connected



So to go from a mini din-8 to a DB-9 to a DB-25 would be:


	din-8		DB-9		DB-25
	1		2		6
	2		6		20
	3		5		3
	4		3		7
	5		9		2
	6		3 or n.c.	7 or n.c.
	7		7		8
	8 n.c.		n.c.		n.c.
