This is a replica PCB made with KiCAD.
This board is not a 100% accurate replica, because the added directly on the PCB a few updates published later by Elektor :
- a fix for memory decoding needed for the expansion board
- the main decoupling capacitor C2 was on wrong side of S25 (activate display) which could reset the computer
- a simple reset circuit with a resistor and a capacitor
- Also replaced the 2708 EPROM by a 2716, which avoid the need of a hard to find EPROM & EPROM programmer, and has the big benefit of reducing the required power supplies from 3 (+5,-5,+12) to only +5V.
