Where possible I'm happy to customise hardware I make. This example is a version of my SAA1099P Soundchip Interface for RC2014 & compatibles, modified for use in a homebrew 6502 computer which simulates a Z80 bus for driving a couple of RC style expansion slots.

Although for this setup only address bits A0 - A7 are available, as the 6502 circuitry is using a 256 byte window in its memory map for the simulated I/O address area. As the original SAA Interface uses A0 - A8 to match the decoding per the SAM Coupe I had to change the decoding circuitry to remove the dependence on A8, which I switched to A0 and used A1-A7 for the base I/O address that can be set by jumpers.
