Every page shows the top and the bottom case of the computer and the boot screen after turning the computer on.
The next screen is a test card that I made in Sinclair BASIC, inspired by the built-in test card of the ZX Spectrum 128. Then I run Tact Meter 1.0 to show the number of T-states per frame, showing the speed of ROM, lower and upper RAM. Other photos include the motherboard, box and contents (when available) and other noteworthy oddities.
