So I had taken appart the program recorder for an atari 130XE when I was a kid, and now I can't record any program...
I was looking at shematics for the program recorder and I can't really wrap my head around how it works, it seems that maybe it uses 1 the right track for music/audio effects, and the left track for the program itself but it like... amplifying it a ton... idk.
here's the shematic for the program recorder:
https://oldcomputer.info/8bit/aptaperec/xc12.gifhere's a pinout for the connector (seems it's not correct, not sure...):
http://www.kbrnet.de/projekte/sdrive-max/sio.pngso it seems when it records data, it just connects straight to the record head from the computer?... also how does the erase head oscillator even work?
or it just magnetizes the head? well I know nothing about tape drives so it's probably all fine there...
but the part where it gets the program data is confusing to me... do I just connect an RCA cable to pin 4 and 3?
what about the +5V/ready and Motor Control pins? I have tried inputting data into pin 3 but it did nothing. (yes I did type the load command)
and perhaps it like... converts the analog signal from the tape into digital 0/5V for the data track...
I am just completely lost on that part...
