Hi! I read about the plans to upgrade the Sound Expander to use OPL2 or OPL3 chips. The chip source would be old Soundblaster cards or compatibles. Why not make an interface to allow the Soundblaster card being plugged into the C64 expansion port? I don't think that much would be needed: Maybe a 14.xxx MHz clock source, some logic glue to convert some bus signals and of course the OPL2/3 address had to be mapped somewhat to make the SB Sound Expander compatible. As a bonus some future applications could even make use of the ADC and DAC on the SB card. I think only old cards would work, because the newer ones have to be put into SB emulation mode first by some DOS program. There are two advantages to using old SB cards: Probably many more are available than Sound Expanders, so many more people could use Sound Expander software. Also, the original C= hardware is not being hacked and can be kept in good condition. Nicolas - This message was sent through the cbm-hackers mailing list.
