I was wondering if anyone's doing any work on the Victor 9000 drivers? I've currently got an actual DMA card for the hard drive in pieces (have scanned both sides of the board) and am gradually piecing together what it's doing, but it might well benefit from someone who's got a bit of an eye for these things, plus it should help produce the emulated implementation? I believe Curt Coder wrote everything for the V9000 thus far? I confess I've precisely 0 experience of writing anything for MAME.
Grateful for any pointers, and happy to help in any way I can!
