Access 2003 does work with Visual SourceSafe 6.0.
I have to assume since access does have support for SCC, then perhaps it is a standard interface? I don’t believe SCC for ms-access will work with SourceGear.
You can find info on using VSS 6 with ms-access here:

I used SCC with ms-access. You can even check-in/check out forms or even queries. So, it does allow more then one developer to work on the application at the same time.
Keep in mind the above SCC for ms-access works by using the un-documented
Saveastext
And the reverse is:
LoadFromText
Type the above two commands in the access debug window, it will give you inteli-sense as to what the options + parameters are.
With the above information you certainly could import + export bits and pieces in and out of ms-access into Source Gear.
So it is a bit of a long shot to get SCC feature of ms-access working with Soruce Gear, but you could cobble together something that pulls objects in and out of Source Gear by using the above two commands.
