I've been wondering if anyone knows whether the scanline counter - also called RCR for Raster Counter Register - is usable outside of the active picture. My goal is to see if an interrupt on every line could enable 15kHz sample playback. There don't seem to be other ways to achieve the same IRQ rate other than by throwing an external IRQ generator (a crystal oscillator with a divider if needed) onto the Hucard.
