The A3000 wasn't really much of a revision. True, it had a hack that made it possible for the CPU to access chip memory 32 bits at a time, but the chipset remained using a 16 bit data bus for all accesses. When running in the 640 pixel wide hires graphics mode using 4 bits per pixel, the memory bandwidth was completely saturated. The really sad part is that a motherboard the AGA chipset (which actually increased memory bandwidth for graphics, but not for the blitter and other parts of the chipset) was ready in an A3000 form factor about a year before the A4000 shipped. Heck, the A4000 couldn't ship in quantities to meet demand because Commodore was cash starved and couldn't afford to pay HP to make more chips. What a series of complete and total failures by management.
