Coverdisk software was MED v3.00 and a game called Amiga-Tanx (link to details of game

Also a graphics ripper and a program for designing garden layouts.
The workbench replacement was something called WorkStation. This was a program based on a shareware package called SID. If I remember correctly; this was an early version of DOpus.
