Traces of my first Commodore 64 code found!
in Nostalgia | Friday, May 02, 2025 | 22:38


During research into my Computer History and some planned "tv-series" concerning my entire life of tv game console and computers all the way back from 1981 until present time, I got a complete shock and "eyes wide open" moment when I discovered something I thought was lost forever.


Cut the story short, in 1989 I sold all my original Commodore 64 tapes, all the Turbo Tapes, my own code, Commodore 64, datasette - the entire lot to a local friend at school.

Years later, in 2014 I started digging into my experiences with computers and everything else, and I always knew that I lost all the tapes and codes I must have played around with during my "learning to code" using the Commodore 64.

I have to give a big thanks to my project SOASC, because when that started in 2006/2007 one of my other friends offered me his Commodore 64C and all the original tapes and turbo tapes he had lying around. During that year, I did a recording of these tapes using M-TAP and created TAP files where I could grab out games. At that point in time I was not looking for any of my code at all - since I already had known it was long lost and gone anyway.

Well, just by chance about a week ago in late April 2025, I was looking for the "Turbo Tape" we called "PIL L", or arrow L along with the "ABC Turbo" software on these tap files. I did find them, but I also got a complete shock when I also managed to find "basic" programs that myself had written in 1989 - that seems to be copied to his tapes all the way back in 1989!

I never found any of these back in 2007 (I was not looking) and I most likely only ripped out Turbo Tape programs (not C64 kernal loading ones). Glad I did that in 2025, because below are traces of my coding years on the Commodore 64.

To be honest, I can't remember anything of what I coded back in those days, everything is just a mind blur of the heavy kind. But, this has my signature writing on them and "my humour", in fact its even 1989 (C) DEMO- SERVICE by Stein E. Which is my name!

Since I have the tapes shown below, I started re-recording them as 44.1Khz, Mono WAV files these days trying to find more traces of not only my potentional code, but also the really get an overview of "what games did I really play while using Turbo Tape 64"?

I have found a shit-load of games I had forgotten very long time ago. It's funny how just a title screen or the first instance of the game triggers memories instantly. I'm so happy for this "happy accident" and it has been a very long hunt.

I have attached the actual Commodore 64 .prg binaries below, if you want to try them yourselves.

So, these are all the Commodore 64 tapes I have gotten from either my friend, or parts of collections I bought in 2007-2009.

The tape with the red circle was the one with traces of my code!



I was just looking for this particular Turbo Tape 64, which I found on many of these tapes. After we press RETURN on this screen it goes away and activates the actual turbo tape system.



This is what I remember way back in 1987-1988 the first week I managed to understand and load Turbo Tapes!



During 1987 or 1988 I came across "ABC Turbo" which was a much better turbo tape software, as it would "show" the loading as flickering color bars. I used to adjust the tape head with these and helped me get rid of "Load Errors" all the time!



My god. This was the first trace of my software found. It was called "JOKK", which means kind of like knee-jerk in English.

The code isn't much to look at, but hey, its my code!



When I run it, some wierd bus type or crane type vechicle is drawn. I have no idea what this was intended for!



Next on the list is this pretty pointless code that was called "WQASER" which is most likely me just hammering random keys onto the keyboard when saving it.



Yup, that is pretty lame. It counts from 1 to 55 or something then asks if I want to repeat it.

Maybe I was teaching my friend to code?



The last item found was called "POLITI DEMO" (POLICE DEMO). What this was intended for I have no clue. The code is a bit longer, but not very advanced.

Line 73 gives me a very important clue "(C) 1989 DEMO SERVICE".



When we run it, the police car slides over the screen with some animation and full screen color flicker in the background. When it stops, it asks me to repeat it or not.



The recording setup!



Recorded onto a Marantz Professional Solid State Recorder PMD660 onto a Compact Flash Card.



One of the tape players, Stereo Cassette Deck's used was SONY TC-K370



The other Stereo Cassette Deck's used (and had to repair the main rubber band inside first) was SONY TC-K555 ESII
