  1. The 6581 Sound Interface Device an interesting piece of Retro Technology. Especially the combination of analog and digital circuitry within one Dual Inline Package, makes it a very nice device, marvelous for its time

    If you have been on this planet long enough, you must have the marvelous music from Last Nina carved in your musical marble memory.

    We're talking about Last Ninja One.

    The programmers made sure that the music for the loading screens was small enough to fit in the 64 RAM, where all VIC data also needed to reside, yet it was large enough to keep you occupied, even if you were loading it from the Datasette, a horrific part of the C64 experience, due to the extremely slow bit rate of the data getting to the computer.

    It was always a struggle between making sure that VIC data was buffered, the program itself was in active memory, and musical data was also buffered in time, in sync in either PAL or NTSC

    The composer of the music made use of many different techniques, including arpeggio, doing it in such away that chords were also simulated.
    Advanced techniques like Attack Decay Sustain and Release were also used.

    I have a lot of experience with the C64 CMOS 6581 sound chip, from the Musical Composer Side of the spectrum and the technical side of the spectrum.
