A walkthrough of the ZX Spectrum game, A Day at the Races. A BASIC type-in game by Andrew G. Bird from the August 1984 edition of Sinclair User magazine. In this video you start the day with $20, and end up with over 10 million bucks after the final race.
From the recording originally sent by Paul E. Collins to http://www.rzxarchive.co.uk/ . Recorded using "rollback", a feature of the emulator which allows you to mark a point, which you can then roll back to later if you get into difficulty, and try again.
