[InHam] Packet Question

[KB9BVN]

I have a KAM all mode TNC Version 5.0

I have the manuals. I have a Yaesu FT-2600.  I have an IBM laptop.
So let's say I want to get on 2m Packet.

I see where I need essentially a modem cable from the 9 pin male serial port 
on the laptop to the 25 pin female port on the TNC.   No problem, I have 
that cable.

Now I need to connect the radio to the TNC. The FT 2600 has a 9 pin data 
port:

Pin 1 - Squelch Signal Output
Pin 2 - Packet RX data Output 9600
Pin 3 - Packet TX data Iutput  9600
Pin 4 - Packet RX data output 1200
Pin 5 - Ground
Pin 6 - Nothing
Pin 7 - External PTT Signal Input
Pin 8 - DC Output (5v at 50ma for powering an external device)
Pin 9 - Packet TX data input 1200

The KAM has a 9 pin male data port:

Pin 1 - AFSK out - Carries tones to the audio input line of my radio.
Pin 2 - XCD - Used to connect squelch line from radio, if desired.
Pin 3 - PTT - Controls the PTT line in my radio. Switches rig between xmit 
and recv
Pin 4 - Same as Pin 5
Pin 5 - Audio Signal input - use with external speaker jack, or pin 4 of the 
radio?
Pin 6 - Ground
Pin 7 - +12VDC input - can be powered here instead of a external powe 
rsupply.  CUT OFF if not using.  It is HOT when TNC is on.
Pin 8 - Same as Pin 6
Pin 9 - Same as Pin 6.

SO...do I have this right?  I need a cable that has:

KAM Pin 1 to Radio Pin 9
KAM Pin 2 to Radio Pin 1
KAM Pin 3 to Radio Pin 7
KAM Pin 4 to NOTHING
KAM Pin 5 to Radio Pin 4
KAM Pin 6 to Radio Pin 6
KAM Pin 7 - Not Used
KAM Pin 8 - Not Used
KAM Pin 9 - Not Used

I appreciate any help I can get.   The KAM software is on 5.25 floppies.  I 
do not have a computer that can read these...

HOST MASTER 64 is one disk....is that for a Commodore 64?  Version 1.18
64/128 COMBO SIDE 1 and 2 - I have no idea what this is.
