> Things is source code management these days even in mainframe
Source code management on mainframes has been around for decades now. Pansophic started selling Panvalet in 1970, and Broadcom still sells CA-Panvalet.
Closer to RCS than to Git in feature set.
> but many shops still have you log into the same "box" to do your development
It is very common to have separate LPARs for production, test and development, even if all three are running on the same physical hardware - the isolation is strong enough that it is rare for something running in one LPAR to cause a problem in another.
The largest shops will have physically separate mainframes for production and non-production.
