That's around five times slower than a PDP-8/S, which was possibly the slowest mini around at the time - already obsolete by 1970.

So it's doubtful it would have been successful as a computing product, although it might have had some applications at the more undemanding end of process control.

It would have been more interesting to use the skills, techniques, and marketing contacts collected during the 8008 project to jump-start an 8080 project as soon as the new CPU appeared.

But the S100 era happened because the Altair had a standard bus that made the system trivially expandable.

Corporate/industrial/academic systems had expensive and relatively complicated proprietary bus and backplane systems, which limited the market and kept prices high.

So... an alternative 8080 system wouldn't have been a game changer unless it was sold with the same open hardware model. At best it would have been an expensive micromini for a niche academic and industrial market.
