Josip Retro Bits | Morse Code Keyer and Commodore 64 | Part Two @JosipRetroBits | Uploaded April 2024 | Updated October 2024, 3 hours ago.
This is part two of the "Viking Morse Code Keyer" video and in this video, we will finally write some assembly code :) We will set NMI interrupt with an external trigger source to detect Morse code signals and for that, we will use MIKRO ASSEMBLER Cartridge.
