Thanks, yes I have been using OSIKCS to generate wav files to test reading with and comparing my saved audio against. My frequencies when saving seem to be off and LOADS are doing nothing at all.bxdanny wrote: ↑Sat Mar 02, 2024 5:24 pm It would be a two-step process.
Certainly, you should download and install the WinOSI emulator from Mark's site if you haven't already. It doesn't directly read audio files, but it does let you LOAD text files as simulated "tapes". And you can use the OSIKCS program, from the same site, to convert valid Kansas City Standard audio files into text files you can use for that purpose.
I have reverted the mods that were done to U62 and U63 and now I am getting a higher pitched carrier signal but it still doesn't seem right. It seems too high frequency.
I need to focus on either getting SAVE working or getting LOAD working.. Tackling them both makes me run around in circles.
Do you know where on the board the carrier signal is generated. I know it comes form the XTAL but having trouble finding where it is getting divided down to the desired frequency.
my most recent SAVE audio attached.
Can you have a listen and let me know what you think?
