While I was messing around with the Indy/Indigo2 options in MAME 0.223 I found out that under slot devices it listed multiple graphics expansion options that support the XL8 and XL24 boards. I just tested it out and had some interesting results. MAME looks like it lets you connect up to 3 graphics boards to the Indy and Indigo2 but the Indy refuses to recognize more than one, in the PROM or the OS. But the Indigo2 recognizes up to two in the PROM and OS. It shows the second desktop and everything. 

Kind of a side note but the second desktop behaves strangely. It has a second toolchest and I can't drag windows from one screen to the other but the cursor goes across just fine. Is this normal? I assume it's because the boards can't share resources across multiple displays but I've never used a real SGI with multiple monitors or graphics boards.

The command to get dual XL24 graphics working:

Code:

./mame64 indigo2_4415 -gio64_gfx xl24 -gio64_exp0 xl24 -hard1 irix65.chd -window -numscreens 2
