I have connected my Blizzard 1260 to the ACA500Plus and it seems to be working great.
I'm struggling to disable it however, in order to use the ACA500Plus 68000 with different profiles (when wishing to use KS1.3 and Workbench 1.3 for instance, or running a 3.1 profile at 48Mhz).
The wiki describes this:
- CPU switch: If you have an A1200 accelerator card that can switch off it's CPU (ACA1233n, B1230IV, B1240, B1260), you can use this menu item to downgrade the computer to the 68ec000 processor of the ACA500plus. If selected, the 68000-only options (such as Action Replay Freezer and CPU speed settings) can be changed. The actual CPU switch is only executed when launching the profile. The CPU setting becomes part of a saved profile.
If I set the CPU switch to 68000 I assume that this is what will disable the Blizzard when I activate the configuration. The CPU Switch option shows two possible configurations: ACA1233n 68030, and 68000. I find this odd as I expected to see reference to the Blizzard there, not an ACA card...?
However, when i save "68000" to the NVRAM and launch the configuration, the ACA500Plus commences the boot, the rainbow flash of the Blizzard 1260 still appears and the accelerator still functions like normal, it is not disabled. Indeed, if I let it boot straight through into workbench the 060 is still active.
So how to disable the Blizzard so I can occasionally use the ACA500Plus' 68000? I do not want to use the Cloaking Device as I still want to be able to use the ACA500Plus ram and IDE whilst the Blizzard is disabled.
Is my firmware out of date here?
My ACA500Plus has ROM v0.129, HW ID $08, Flash rom ID $1C/$16
