Just bought aca1221lc for my amiga1200. Installed it on amiga, added RTC on accelerator. Jumper on parking.
But Amiga shows only black screen after turning on.
If hold left mouse button and turn on amiga, red screen appears for a second and then amiga boots to workbench as usual.
ACAtool shows that the accelerator works normally.
I'm new with accalerators and wiki not explains me how to use this accelerator and configure it.
How I can boot amiga without holding LB?
