Robert Erskine ZX81 Battle of Britain

Post by Gagarin » Thu Jan 17, 2019 3:24 pm

I seem to remember playing this game on my ZX81
It was a text only game simulating the Battle of Britain and you had to use an actual map of South east England using the A to Z / 1 to 9 co-ordinates provided by the program.
I have searched everywhere on the internet for this game but cannot find it
Can anyone provide the listing for this game?
with thanks

Yes - saw that on World of Spectrum. Good luck with the ZX81 version. Someone may have a copy on here.

Hi, I stumbled upon this thread during some nostalgic research. I am the original game designer, Robert Erskine's son, and did ask if he had a copy for the ZX81.

To paraphrase; a working original will be hard to come by as digital cassette tapes don't wear well. At the time it was difficult supplying Boots, Smiths, etc. with reliable copies, as the mass production technology was still fairly crude, and geared to audio. He spent weeks with commercial tape engineers in London getting it right but most of the problem was with the ZX81 itself.

While it's not the same thing as having the original it is possible to run the game on a pc with a ZX Spectrum emulator;

Good luck in finding an original copy for the ZX81.
