<This notion of cooking up or breathing new life into an old 8-bit model to <run *NIX is probably a mite more than has been considered for one reason. <*NIX tends to want to use virtual memory, without which many systems would <quickly choke. The old CPM-capables don't support VM. A good reason for <this is probably the lack of performance. Unix didn't always have the idea of virtual memory. See Minix for an example of that also V4 and maybe V5 unix didn't either. Also It's been done! UZI uses the total swaping model, IE: processes are swaped out of core to make room for others. Allison
