Didn't lisp machines have Hardware traps of some kind ?
- ScottBurson 12y agoLots of them. But the CPU wasn't even pipelined, never mind superscalar, so adding traps was easy -- just more microcode. For example, there was tag type DTP-GC-FORWARD. When the CPU loaded a word from memory with this value in the tag field, it would automatically indirect through the pointer contained in the word.
