WIP: Macintosh IIx (68030) with RasterOps 264 video card showing the video card's BIOS screen. If I'm not mistaken, this is the first time ever that a Mac emulator has shown video from a properly emulated NuBus video card instead of just shunting a fake driver into native code ;-)

I believe you really are the first, too. It's a long time since I've seen that screen - it brings back memories.

Here's a screenshot from real hardware (actually the SE/30 PDS variant of the board, but it looks like it works quite similarly). The SE/30 motherboard I bought arrived today and I successfully dumped the video declaration ROM from it (it's separate from the main system ROM SIMM and contains mostly credits for the SE/30 hardware since the driver is very tiny). The emulated SE/30 detects the display and puts up the familiar Mac "rug pattern" but doesn't go farther yet.

Alright. Supporting the next video mode the RasterOps board switches into nets us this:  VRAM layout in 1 bit per pixel mode on that card is nearly Apple II hi-res levels of weird. Also, it doesn't like my harddisk images created on the (emulated) Mac Plus for reasons I need to investigate (I see where in the code it's rejecting them, I just don't know the details yet), and nobody has a clue how the SWIM works so no floppies pending a major deconstruction of the .Sony driver. Whee ETA: declaration ROM dumps and chip lists for other Mac II NuBus video cards accepted, PM me ;-)

Hang on, isn't the SWIM just like the Apple II disk drive circuitry (the "Woz Machine"), only integrated into a single chip?

@Anna Wu: whooops... I forgot 1 line in the NES commit yesterday I'll fix famicom soon. thanks for testing @Arbee: wonderful news. I've never seen those macintosh machines at time and I'm quite curious to see them in action! btw, could your HD problem be related to the following crash I was getting on SDLMESS? http://bugzilla.mess.org/show_bug.cgi?id=1664

Found a short info about the SCSI controller for the FMV-Towns. Unfortunately no more details. Fujitsu is also talking about this controller. Maybe the FMV-Towns is a newer model as FM-Towns.
