I'd disagree. Chipset and architecture wise, there is not much that makes the A600 different from an A500. ECS is almost zero improvement over OCS for most use

I'd disagree. Chipset and architecture wise, there is not much that makes the A600 different from an A500. ECS is almost zero improvement over OCS for most use cases. Both are on the same old ~7mhz 68000 CPU, which was absolutely ancient by 1992 when the A600 was released. The A500 was a cost reduced A1000, and there is little real difference to the user (other than kickstart in ROM.) If anything, the A600 is a downgrade because it's missing the Zorro expansion bus...
