This is my now finished home built Z80 based computer in an earlier state. 32K RAM, 16K ROM, 4 MHz.
Yellow wires are address wires, red wires are data wires and black wires are miscellaneous.
I began building it in the beginning of 1990 as an evening activity with the local Young Scientists club. At the time of this photo It's almost finished, apart from the clock-circuit, programming and debugging. The only hardware it lacks is capacitors for the clocks and the IC's, and some wiring for the serial interface.
Update May 14 2011 - I found the block drawing for it and the design for the clock circuit so I now know what capacitor I need to make it tick. Yay!
Update June 2021 - Finally got it working after thoroughly checking all the wirings and getting inspiration from the vast resources of internet.
I had a choice, to get the computer repaired or replace it. It would cost almost the same amount, so I got a new computer and had the files transfered to it. now the pain or reloading the programs, remembering passwords, regaining the websites that I lost the bookmake to, and ofcause, setting it up to the way I like it.
When a dell technician tells you to get a screwdriver and pry things apart, don't do it!!! As a result, I'm offline for a week while I'm traveling. Ok, so you shouldn't drop your laptop to begin with either. Thank goodness for public libraries with internet connections!! And the nice people at Darien PL who are letting me spend lots of time at a public computer.
