1. First solder all the resistors, the value is printed on the PCB.
2. Solder the 100 nF capacitors and the two 20 pF capacitors.
3. Solder the 20 MHz crystal.
4. Solder the Tantalium Capacitor and the reset switch.
5. Solder all IC sockets. Be aware of the pin 1 positions.
6. Solder the USB-C FTDI. The LEDS (Watch the polarity!).
7. At last solder the two digitasten, the two I/O female headers and the 470 uF elco.

Before you solder the USB-C FTDI mount the spacer first.

Before placing any of the IC's power the FTDI from your PC, The green LED will light saying that you have power. Disconnect the USB-C cable,

The PIC16F877 has to be programmed with the hex file first. Insert all ic's into their socket.

Check if all is inserted properly and connect the USB-C cable. The RX led will light up for a short time.

Open a serial terminal program. Select the FTDI  device and set the baudrate to 2400 8 bits en 1 stop bits (8N1). Press the reset button and a '>' appears on your screen. NIBL is waiting for a command to enter. Type PRINT "Hello" <enter> and if all went well on the next line appears Hello.

Congratulations, You have a working SC/MP system running!
