Doing any action with the primary purpose of manipulating share prices is illegal, and that's what it sounds like was going on here. They sold stocks with the intent of making that system behave stupidly.

Not many people were buying Apple II games, and Amiga is a little after when I first started buying games (82/83). If you were into games in the UK, the chances are that you had a Speccy.
Check out the Crash software catalogue http://www.crashonline.org.uk/cat01/index.htm from 1983. Vast majority of prices in the £5-£6 range. There's a few up to around £7 and The Hobbit at £14.95, but that included the book.
£6 in 1983 is (according to the BoE inflation calculator) equivalent to £15 in today's money, far cheaper than the £30-£40 that most of top sellers go for today.
