The 8 level deep stack of 8008 precluded most complex software though. It was also 4 to 6 times slower than an 8080 running at 2MHz, had a very small package that required extensive demultiplexing, slowing it further.

There were multiple kit computer based on 8008 in the era, ex. Mark 8, the French Micral, but they were severely hampered compared to something like the Altair 8800 and it's unlikely they could have had a similar story despite launching earlier.
