Files were checked into bundles called Tracks that could be Committed atomically.

No check-in could occur without a Defect. (Wonderful feature when managing S/W development).

Builds were based on Levels (groups of Tracks) that could identify exactly which Defects were fixed. (Again, wonderful for managers).

Clients on AIX, OS/2 and VM/CMS (Hey, its an IBM product!)

IBM Developed AIX and OS/2 using CMVC.

I was part of a ten-person team that managed CM for IBM OS/2 development. We had thousands of active users. CMVC handled it without a hickup.

The closest tools I've been able to find to match it are:

* CCC/Harvest (now called AllFusion Harvest) * Lucent Sablime
