The EPG Sr. was the second iteration of the EPG software which ran on the Amiga 1000 and 2000 platforms. Like the EPG Jr., the software could display text ads, however it also had a feature for full-screen advertisements.
The software had many different variations, including a full-screen version that looked a lot like the EPG Jr. with the ability to display full-screen advertisements, most likely between time intervals, and a split-screen version that looked like the first version of Prevue Guide which allowed text and image advertisements to be shown in the top half of the screen.Unfortunately, we do not currently have either version of the EPG Sr. software.
