GI made a 10-bit wide ROM for program storage, as I recall. I think the 10-bit instruction word was the single greatest liability, resulting in inefficient memory usage when memory was expensive--and slower execution time.
For the time, not a bad effort, particularly when contrasted with the National 16-bit PACE, which was loosely based on the 4-accumulator DG Nova design and which required special buffers for integration into TTL designs. --Chuck
