When i was a kid, my dad had a Mac with the A/V PAL-SECAM cards. Hooked up a make-shift copper wire antenna and wrote a decoder with the free codewarrior cd folks gave me at Paris' Mac convention (we were 12 and crazy I guess). Good opportunity to learn powerplant and c/c++.
I ended up brute forcing most of it as I did not really understand what I was doing, but it turns out, with enough time, you get things going.
Wish the pages were still up, I lost that software long ago, and I'm sure my code was garbage (not that its much better today, but at least I can blame Claude..) and fun to read.
The 90's were fun.
