However, developing the OS, hardware, and other things was incredibly costly, and the sales didn't ramp up fast enough to overcome the $$ invested. Real OS's are time-consuming to create." ---------------------------------------------------------------------------- If I remember correctly, Siemens and Intel were involved and the operating system was created for an Intel chip (432 ?) that was designed for Ada. I also believe it had very odd input-output architecture. The questions are what happened to the BiiN source code? And if available, what would happen if it were hosted on a modern CPU?
