My ZX81

[crankorgan]

I built a linear 5V 3amp supply in an old computer supply case. The Keyboard is built from a Cherry space saver I got off Ebay. Inside the TV modulator is a reverse video board that drives a security monitor. The board has internal 16K that gets bypassed by a 8K to 40K battery backed up external Ram Pack. Keyboard is removable!
