This is a great project, and great backstory. This miniature itself was made in 1981, just a few years after the MZ-80K – a tape-based machine with a 2 MHz CPU, 20 KB of RAM, and a built-in monochrome monitor – hit the market. The miniature has since been upgraded with some modern components including a Raspberry Pi Zero W and 1.5″ TFT screen giving this retro miniature a modern upgrade – I especially dig the hand-painted keyboard keys and the glowing green operation LED on the front panel!
The 1/5 scale model of MZ-80K is my artwork in 1981, when I was a high school student.
It was mainly built by plastic plate of 1.5mm thickness, because its design was mostly square-shaped.
It took effort to trace accurate shape, paint for good appearance.
Especially it was too laborsome to paint the each key-top by hand, I cannot do it again now, haha.
