Thor-Desk

In May 1988 Urs Koenig bought his CST Thor XVI. Due to the fact that his two major used system utilities (QJump's QRAM and Ultrasoft's QKick) did not run under the Thor XVI's operating system ARGOS at that time, Urs decided to reinvent the wheel and write his own user interface/desktop system for the Thor range of computers. During 1988 alpha and beta version were sent to individuals (Thor XVI owners), QJump, THOR International (CST, Dansoft). In autumn 1989 the package was eventually launched at the “European Microfair for Sinclair Users” in Brussels. The package was RTM in June 1990 and got renamed to QTop in spring 1991.
