My board used a pair of Motorola MC68705P3S’s. Each microprocessor had 1.7KB of internal EPROM. This board was the first commerial use of the MC68705P3S and went into production using pre-production chips. There was a bug with the oscillator section that caused a respin of the pre-production chips before final release. As I did not use the feature with the bug, Motorola agreed to supply me with pre-production chips so that I could release my product.
Those were the days where you could actually talk to the chip designers!
