The era of object-oriented programming began some time in mid 1980s. New languages started to appear and one them, Smalltalk, began to be available on the then ubiquitious PC. Smalltalk/V was the version for DOS. It offered a rich set of graphics, fonts, shapes and it was as close to the original Smalltalk as it was possible then.

(See the description below.) From the programmer’s point of view, there are two enhancements to brag about.

You can stop and and pause the video, direct it to an absolute count…
