Sequential Circuits Model 64 Sequencer

(sorry for the old photo)

I dumped the contained EPROM (which works in Vice), including PCB pictures HERE. HOWEVER. Unless someones emulates the onboard ACIA and PIA chips in a Vice ad-don, this is really just an exercise in digital archeology.

EDIT (2013) This cartridge has been used by the MMA to showcase the enduring power of the MIDI Standard.

SID filter emulation ... perhaps a _tad_ bit too extreme.

Extremely distorted 6581 filter running a combined Waveform arpeggio.

Yes I know this is not strictly accurate but its a fun diversion while i tune it.

Another chip in the wall

pain. MPT-03 mess. pattern recording success. no brain left to explain.

Evolution of sucking

Choice to desolder chips:

1)5$ (and millions of curses)

2)20$ (less curses but a lot of frustration)

3)200$ (And worth every penny.)

CMS (Dual Philips SAA 1099) Recordings

Here's a rarity, carefully sampled for you.

Before the soundblaster, there was the Creative Music System (CMS) (AKA GameBlaster), which contained two Philips SAA 1099 chips.
It pretty much bombed since the OPL2/Adlib was all the rage at that point.

Nevertheless, the thing has some charm. Here are two recordings made on a SB 2.0 CT1350A (with the SAA chips factory installed as legacy option)
