(text "okay so here's the idea: \nthere's a 32k voicebank for george's voice\ni need a way for the cpu to asynchronously\npick a voice note to be played, and then\ntrigger an interrupt for when the sample ends\nso that we know that the next sample is ready to be queued up\ni'm thinking that the cpu sees an 8 bit register\nto select a voice sample and some extra stuff,\n each sample is 2k long, so 16 are available, \nleaving 4 bits to do stuff like pitch shifting\nor setting volume, then the voice circuit \nreads from the register, selects the corresponding sample\nfrom memory, sends the sample data to a shift register\n(idk how digital audio works so i'll have to look into that lol)\ni'm gonna wanna use a binary counter to tell when we've read 2k\nof sample data, and then when we hit that amount stop reading from the rom,\nsend an interrupt, and wait for the next instruction"

(text "okay so here's the idea: \nthere's a 32k voicebank for george's voice\ni need a way for the cpu to asynchronously\npick a voice note to be played, and then\ntrigger an interrupt for when the sample ends\nso that we know that the next sample is ready to be queued up\ni'm thinking that the cpu sees an 8 bit register\nto select a voice sample and some extra stuff,\n each sample is 2k long, so 16 are available, \nleaving 4 bits to do stuff like pitch shifting\nor setting volume, then the voice circuit \nreads from the register, selects the corresponding sample\nfrom memory, sends the sample data to a shift register\n(idk how digital audio works so i'll have to look into that lol)\ni'm gonna wanna use a binary counter to tell when we've read 2k\nof sample data, and then when we hit that amount stop reading from the rom,\nsend an interrupt, and wait for the next instruction"

### Video Controls $4200 & $4201

Each keyboard row is mapped to a read-only 8-bit register, with each key mapped to a single bit. Due to the design of this keyboard, Row 5 has 5 unused bits
