This is a CP/M 2.2 computer (pre-IBM). It is working.
It is unique in that it uses the the SIM/RIM instructions and SID/SOD/RST6.5 pins for Serial IO. It uses a 5V USB serial adapter for power and communication to your computer (using a serial terminal program).
There two problems with this approach in that the processing delays between Serial IO means that character can be missed if data is sen...

This circuit uses the Buck/Boost Converter circuit for typically for use in a lab bench power supply. It features both adjustable voltage AND current using potentiometers.
Without a buck/boost converter,a computer power supply can only provide a 3.3V, 5V and 12 supply lines. With the buck/boost converter created with the aid of a 555 timer, adjustable voltage is allowed. A simple transistor is us...
