Merv - I'm assuming that the DEA Swift is a used machine since Brown and Sharpe bought DEA a number of years ago. Their web address is:

We're still using the DOS version of Tutor, but recently purchased the Windows version just for the DMIS-to-Tutor translator that is bundled with it. I'm not sure which version ours is, but it's the latest and will run under Win NT4. I have it installed on a workstation using the "Demo" mode.
If you search the B&S site, you'll find only one Australian distributor is listed (in Clayton, Victoria). You'll need to contact them for any software upgrades. Alternatively, you could email B&S in the USA to see if there are any other distributors that aren't listed on their web site. If I can be of any further help, let me know. Good luck!
