I'm familiar with how the architecture was designed, and if I had chosen, could have ported code. However, like I said, it didn't really perform any faster than a PC of the time on any code (even ones optimized for the platform). Writing massively multithreaded code, maintaining it, tuning it, and then keeping an entire separate platform for something that isn't measurably faster for a wide range of problems is a huge cost/burden to developers.

I certainly cared about performance but like most people we found that general purpose computers that ran all our codes quickly were not a cost/burden to developers.
