silicium Posted February 14, 2008 Report Share Posted February 14, 2008 Giving for free + shipping cost (from France) a Packard-Bell soundcard for 16-bit ISA, was tested some years ago. Here are the interesting SMD parts onboard waiting for a MBFM project:one YMF262-M one YAC512-Mfour TL074Cdecoupling caps14.318 MHz crystal, not SMD but HC49U package (it is easy to build an oscillator, just Google for schematics using a CD4069UB inverter gate biased at VDD/2 with a resistor between input and output, make sure you're using an unbuffered version UB suffix, and use the remaining gates for buffering your oscillator's output)other parts:one GD4053B SMD (cmos analog mux)one 7805 voltage regulator TO-220 package, with screw & nut (no soldered tab)one X24C00P EEPROMone 12 MHz crystal, HC49U packagetwo short crystals, HC49US or similar (R245KD55, R169PD335)one Crystal CS4231A soundchiptwo Packard-Bell asics, probably for DMA and old CD-Rom control (has three sockets for Sony, Mitsumi, Panasonic drives from the days before IDE/ATAPI)three stereo jacksThe card (found in a PC on the sidewalk) came with a Korg daughterboard that I will put in a box as a standalone GM expander 8). There is also a 558 quad timer (4x 555) in diL package that I am likely to recycle unless one really wants a complete card for gaming :P Quote Link to comment Share on other sites More sharing options...

Rare! Chances are, that's somewhat more than a GM card ;) Let me know if you don't want it heheh Quote Link to comment Share on other sites More sharing options...
