Here's a nice picture of a PS300 with a caption that mentions both a vector display and a raster display (I think the little one in the middle is a dumb terminal): http://www.inflab.bme.hu/hist/pictures/esps300pic.html In any case, it was the dataflow software architecture that I found interesting about the machine, and it reminds me of a hardware question that you or some other hardware guru can help me with. I found a dataflow language intriguing because it makes it clear what processes can run in parallel. Everything is asynchronous and event driven, which maps nicely to the real world and even maps well to modern GUIs and operating systems. So, why are all modern CPUs synchronous? Does a clock buy you anything besides simplicity? Why not let logic run as fast as it can and add sync points as required, the way nature intended. -- Doug
