I’m not overly familiar with the Mac drivers, so I’m not sure if this is me doing something wrong, known limitations, or bugs.

If I try running Mac II booted from a hard disk with two hard disks connected, ADB locks up after the desktop appears. For example if I use this command, the mouse/keyboard won’t respond after the desktop appears:
Code
mamed macii -ui_active -nb9 spec8s3 -hard1 mac711 -scsi:2 harddisk -hard2 SuperMac.hdv

However, if I boot from a floppy, I can browse both hard disks and copy files between them without ADB locking up. For example, this works:
Code
mamed macii -ui_active -nb9 spec8s3 -hard1 mac711 -scsi:2 harddisk -hard2 SuperMac.hdv -flop mac_flop:sys608

I occasionally get stuck keys, so I guess this is just ADB HLE weirdness?

Weirder than that though is that System 7.1 doesn’t see some files on the hard disk while System 6 does.

With that previous command (booting from System 6.0.8 on floppy with the System 7.1.1 Pro hard disk attached), I can see the PowerTalk Folder, System 7 Pro Read Me folder, TeachText, etc. as well as any other stuff I add myself.

However, if I boot from System 7 itself, I only see the System Folder in the root folder of the hard disk. For example this only shows the System Folder:
Code
mamed macii -ui_active -nb9 spec8s3 -hard1 mac711

I tried rebuilding the desktop file on the hard disk, but it didn’t improve the situation.

This was all with debug builds, I haven’t tried a release build. Is there something I’m doing wrong?

OK, the missing files in System 7 fixes itself in a release build, so I guess that’s down to a lurking uninitialised variable. ADB locking up with two hard disks when booted from one of them is still present in a release build.

Something is definitely faulty with the ADB HLE, since macpb100 loses the mouse when booting from floppies and loses the keyboard instead when booting from a hard disk.

Osso worked out which uninitialised variables were causing the issues with System 7 filesystem access, so that’s one less thing to worry about.

I’m still getting issues with multiple monitors on emulated Macs. At this point I’m wondering if my PC is haunted. Even if I just use a pair of m2hires cards in a Mac II, it misbehaves. I can move the mouse pointer onto the second monitor or drag a window there, and the OS thinks it’s there, but it isn’t drawn. The second screen just shows the desktop pattern. After dragging it back onto the first screen, (have to do this blind), the contents of the window will be corrupted.

I can confirm a pair of m2hires cards acts weird (the system locks up when I open the Monitor applet, which is definitely bad). A pair of 48gc cards works great though.

ETA: cb264 and 48gc are both "harmless" - I can run a 48gc and 3 cb264s in macii and it works fine.

Just playing around with this on Linux with Mame 0.243.

$ mame macii mac711 -window -ramsize 8M -effect none -video opengl -nomaximize -nounevenstretch -nb9 48gc -nba cb264 -nbb cb264 -nbc cb264 -noautosave

This boots up with 4 monitors like R. Belmont was saying (I assume this is what you meant by "a 48gc and 3 cb264s"). The 48gc card can be put into a color mode with no problem. Mame crashes as soon as I try to put any of the cb264 monitors into a color mode.

Ignoring MAME exception: cb264: unknown video mode 50529027

Fatal error: cb264: unknown video mode 50529027

Didn’t ArBee already fix that in master?

Correct, but they were using 0.243.

Sorry, the Macintosh Display Card is going to have incorrect refresh rates for a while. Calculating the PLL-generated dot clock frequencies is going to take effort.

edit: That was a short while.
