Using this computer, I have written lots of programs using Basic and machine code. You can do a lot using 48k of memory. (This is more than the Commodore-64 which had only 40k of usable memory.) I have also made some music using the MIDI interface that was also donated. Some other gadgets I donated was a light-pen, two joysticks and lots of games.
The ZX Spectrum was a very useful computer. Now it has found a new home. You can visit it at the Internet Museum.
I can still play may old favorite games using emulators. There are web-based emulators and emulators for lots of operating systems. There are also emulators for your smartphone running on Android. We must perform a Quirkafleeg!
