 * c64: the C64 program source;
 * img2c64: browser-based tool that converts regular images to C64 hi-res bitmaps and colormaps and lets you quickly swap foreground/background color choice for each 8x8 tile;
-* measure: BASIC program to control the C64 filter and output gain stage - actual measurements of the MOS 8580 chip in our C64 (C64C, ser. no. HB41416598E, made in Hong Kong) are available [here](TBD);

 * octave: various GNU Octave scripts to generate program data, extract IRs, and simulate the MOS 8580 SID analog filter, output gain stange, and output buffer;
 * spice: LTspice schematics of the MOS 8580 SID analog filter, output gain stage, and output buffer;
 * src: A-SID sound engine with a full virtual analog model of the MOS 8580 analog filter, output gain stage, and output buffer, both implemented in C;
