Didn't IMSI own TC when it was version 17?
It's always been IMSI or IMSI/Design, but with different "groups" running the show.
In 2018 Dave Taylor, et al were shown the door and a new group (led by Zunair) from Lahore, Pakistan took over. I just looked at the TurboCAD site and there's nothing about Bob Mayer or any of the Board of Directors. I guess it's IMSI in name only
My memory of the leaders:
Rob Berry -V1 to V7
Mauritz Botha - V8 to V17 (?)
Dave Taylor - V18 to V24 (2017)
Zunair Attif - V25 to present
