Bridgeport

I'm looking for the EZ-Link software for the bridgport boss 8.
Also looking for the 5 1/4 floppy mass storage device for the
Bridgport R2E3 machines.
Dose anyone have information on the R2E3's that had tool changers?
I'm thinking the tool changer add on must have the mass storage
device, or DNC link.
I have tried Hyperterminal, and 30 day trial software, BobCad,the
boss 8 goes in to instant error as soon as data is transferd.

Any Help would be great
