A cheat entry for now, as its possible that all 4 of the games were actually released – so this is more of a call to try and find these games and get them digitally preserved and available.
Piper Software was flagged up to GTW64 by contributor Håvar (who kindly loaned us Pluff for preservation a while back). He has mentioned that there were four titles due for release by Piper Software called Dinosaurs, Birds, Astronomy and Aircraft.
They were all educational titles, and were part of Piper Books LTD. Each title came with an information book, so the game was likely sold in book shops.
Dinosaurs was fully preserved in May 2020 and can now be found on this page we’ve added:
Can anyone help us to preserve the rest of the games? We guess that they had a very limited release overall, although they were all released on the ZX Spectrum…
