Gottlieb/Mylstar 2nd generation sound board fully reproduced on FPGA
All,
I spend the last month doing a full reproduction of the Gottlieb/Mylstar 2nd generation sound board used in 3 Stooges, M.A.C.H.3, Screw Loose, Liz, etc. Although I never heard the sounds from the original box, I think I am damn close. It was a hard piece of work!
The original card contains an awful lot of tricky components which I all did from scratch, such as:
- 2x R6502 CPUs (which I already had from the 1st gen card)
- 2x AY-3-8913 programmable sound generator
- 1x SPO0250 voice synth
- Timer logic
Unlike the SPO250, the AY-3-8913 was quite straight forward as the data sheet contained all info needed. For the SPO, I had to make some lengthly trial and error testing to get those freaking FIR filters right. Now it clearly says: "Ohhh, you´r a wise guy eh".
I will put a video on youtube this weekend to let you hear how it sounds and to comment if it´s close to the original. Beside the SC01 and laser disc interface cards, I am close to completion of the Gottlieb/Mylstar stuff.
Cheers, TRORT
