Same here, going into UNIX back in the early 1990's, after using the Borland IDEs across MS-DOS and Windows 3.x (and being aware of their OS/2 versions), felt like time travel to the genesis of programming, CP/M style.

Thankfully a professor pointed us to XEmacs, which I managed to get my Borland experience back, which became my UNIX companion until KDevelop, Eclipse, Netbeans came to rescue.
