My first A3000 came with KS 1.3 and 2 Workbench 1.3 disks. Because OS 2.0 was under development when the A3000 was released, it aslso came with KS 2.0 and several WB 2.0 disks. This original OS 2 was primitive. Later WB 2.1 was released and fully devloped but I think the KS was the same. Also there were two major revisions of the A3000 motherboard, the first (yours) with KS images on the HD (and a bare minimum Bios on rom), and the second with KS on the rom. Unfortunately, the rom sockets were NOT pin for pin compatible, though a mismatch was not destructive. There was also something about a rom daughterboard, but, I have forgotten the details.
Anyway, the KS disk is not normally formatted (therefore unreadable), but there was a way to back it up and copy it to your HD. I'll have to read-up.
