> I also still have a copy of the Liverpool Software Gazette which had "Stargate: A 3D Planetarium", (from around 1980).
Tidying up and I just found it. It's May 1980. I was sure I had lots of them but only found three (Nov. 1979, May 1980, Feb./Apr. 1981). Also found my Leasco Basic manual from 1969.
I'll put the LSGs up on kwhitefoot.neocities.org over the next few weeks. Might even try to see if any of programs can be made to work.
