"Now-days"? There are some that do that, some of which are still in operational shape. Some VAXen, in particular, have something called "writable control store", which is essentially microcode RAM. > You have a lot of byte code virtual machines out there. Such as every x86 processor since, what, the Pentium? They're all RISC cores (designed for and) running an x86 emulator. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
