it has been many years since the c64 was released, and we all forget how things work this is a little guide to the basics of powering up and using the c64 wiring up firstly, power up the c64 using an official or newer third party power supply this provides both 5v dc and 9v ac into the power port connect up either rf or composite/s video cable to the rear initial screen making sure your av is connected to a monitor that can receive 15khz low resolution signals (so old crt, an ossc with composite add on, a retrotink etc ) when you first turn on the power switch on the commodore after around 4 seconds you should be presented with a basic screen infinite print loop a super simple test is to write the following to print out hello world 10 infinitely press escape to stop the code running 10 print "hello world" 20 goto 10 run to see the current program in memory you can type list to display it to wipe out the program and start again type new counting a quick counting program to add up and display the number is as follows 10 a=1 20 print a 30 a=a+1 40 goto 20 run user input here is an example of asking for a users name and then displaying it 10 print "hi, what is your name?" 20 input name$ 30 print "hello "; name$; ", i'm bbc" soft reset to reset the c64 instead of using the power switch, you can perform a soft reset by pressing run/stop + restore to software reset
