I was very active on the CPC back in the day.
When I was at university someone one asked "Don't you do stuff in Amstrad Action" which was the weirdest bit of fanboying I ever had.
I'm currently writing some utilities to inspect ROM files and just discovered that for some reason the Protext V1.22 has 13 hidden RSX commands.
