Part 1 - MSX Build Power and Reset

The guy who designed this board did up an excellent 68-page document for his board. It goes through theory of operation, design methodology and step by step instructions on how to build the thing. Most instructions for PCBs just say start with the low-profile stuff first and then go up from there. Which is fine but what Alvaro did was introduce a function at a time so will be will following his instructions which includes testing for each function. It starts with the Power and Reset This is the circuit for the power and reset simple. It doesn't use a regulator or have protection, so the power consists of a socket, couple of caps and LED with a resistor

See pretty simple

This is the reset circuit

And this is it in real life

WOW!!
