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. Dave Wargo 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. -- Dave Wargo ucbvax!sdcsvax!sdics:wargo Brought to you by: Powdermilk biscuits, in the big blue box, enables shy people get up and do what has to be done.
