Hm... you still didn't quite answer my questions:
1) You said: "i have the kenwood 232 interface box." Does this mean you actually have a Kenwood IF-232C right now? (Yes/No)
2) You said: "but hear problems when the dsp 100 is used in the acc 1 slot." Does this mean you tried the Kenwood IF-232C and had trouble with it? (Yes/No)
It sounds like you meant that you heard there might be problems using it.
If you do have the original Kenwood IF-232C (again I'm still not sure), then give it a try. Like I said, I have one and it works fine with the TS-850/DSP-100 combo. Just plug it into the CONT OUT port on the DSP-100 and give it a try.
_Some_ of the 3rd party substitutes definitely don't work. The Piexx one and the cheaper ZLP one definitely don't (at least, not for me). I _think_ the more expensive USB one from ZLP does. It's the one at the top of this page:

Note: remember that you need to use 4800 baud and 2 stop bits when setting up the serial connection on the computer in order to talk to the rig.
I think I know the John you're talking about. His name on the forum is 'skullman.' This is his profile:

Unfortunately, I haven't been able to talk to him directly because although we're both in northern California, he's too close to me for skip, but too far for line of sight. We do chat on Yahoo! Messenger once in a while though.
Also, I think I may have talked to you before too! If "imbrad" means that your name is Brad, and you live in south Alabama, then we've definitely talked a couple times. I'm the Bill in San Francisco who has the Kenwood TS-950SDX. Hopefully that rings a bell.
Note that while my rig is voodoo modified, it's not an official VMSDX as I did the mods myself based on the info on Mike's web site with a few of my own tweaks thrown in. You can see a picture of my station if you click here:
