Tono Theta 5000

Not really something I can claim to have had, but a friend had one, sans keyboard, and I found a keyboard for him. Then a second unit popped up, with keyboard, and I snagged that and passed it on to a different friend.

I did however find a copy of the Service Manual courtesy of Reg ZS1ADC, and scanned it. The Tono 5000 uses an 8031 processor. Kind of boring.
