years ago (90-95) I had an A1000 with AOS 2.1 softkicked on it, the chip mem module + scsi sidebox, along with a (whopping) 80mb external hard drive the size of a shoebox that sounded like a dc-10 on takeoff.. I still had to use the 1.3 kickstart disk, then the 1.3 workbench disk, which determined whether the system was in wb1.3 or 2.x, mount the HD, softkick the 2.1 roms if it was in 1.3, or execute the dh0:s/startup-sequence if in 2.0. Also had an external floppy drive with it, and was plugged into a 1080 monitor. And the classic polygon style mouse, that died due to an alaskan malamute with really long fur. Sitting on top of the 1000 was a stock a500 plugged into the rca ports of the 1080 monitor. I have a photo of this somewhere, I'll post it when I get the chance to scan it.
