I'm Mike, back in April 2020 after a 30 year career in the audio industry (software development, hardware design, DSP, Plug-Ins etc), like many I found myself with a little more time on my hands than I might have expected...
So, I decided to go back to where my interest in technology began, dust off my Z80 assembler language skills and try some ZX coding - only this time with development tools I could not have dreamed of when I was first introduced to these machines in my youth.
I think it's fair to say that some significant 'mission creep' has set in - after creating some ZX Spectrum games for my own amusement, and an emulator, I decided to make them available to a wider audience through a small business - Vintage Software Systems Ltd based in Oxfordshre, UK. The games are available as .tap and .tzx files for 48K ZX Spectrum emulators, and also as audio files for loading into original vintage hardware. Please feel free to take a look.
