C64 Programing Publications:

While searching on the net, I have found this retro site hosting memorable items related with first home computers in Turkey. I fondly remember submitting a few computer programs (in BASIC) to the program döküm eki (programming supplement) of Commodore monthly magazine published by Teleteknik company (distributor of C64 in Turkey) when I was in secondary school. Without any further ado, here they are:
