Does anyone know what type of tape drive a 3M HCD-75 Cartridge Tape drive is? Specifically, will it work in an Apple SCSI system? If it is not SCSI compatible, can it be modified to be SCSI compatible (like with a ???->SCSI controller)?

I want to make a cable from the data port of the modem to the user I/O port to the commodore... The Commodore manual says you can stick a modem there, so that is what I intend to do, and I do not want to spend 50 bucks buying a cable, so I wanted to make one myself. The user I/O port has 24 pins, and the configuration is as follows in the manual : 1 2 3 4 5 6 7 8 9 10 11 12 ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ ^^ a b c d e f h j k l m n Pin Type Note 1 GND max 100 mA 2 +5V 3 RESET 4 CNT1 5 Sp1 6 CNT2 7 SP2 8 PC2 9 SER ATN IN 10 9 VAC max 100 mA 11 9 VAC max 100 mA 12 GND A GND B FLAG2 C PB0 D PB1 E PB2 F PB3 H PB4 J PB5 K PB6 L PB7 M PA2 N GND Now the problem arises when I try to figure out what the hell these abbreviations mean.. I mean, I know what GND, 9 VAC, and +5V mean, of course, but what does PB5, SP2, and PC2 stand for? Could anyone de-mistify these terms? In the Modem manual, things are a little easier to comprehend... Pin Description 1 GND 2 Transmitted data 3 Received data 5 Clear-to-send 6 Data Set Ready 7 Signal Ground 8 Carrier detect 20 DAta terminal ready (DTR) 22 Ring indicator. Does ANYONE knopw how to match these two ports up correctly? If so, please mail to laba-3eh@web.berkeley.edu, and I will be eternally grateful.
