Is this the one that depends on the compiler for its security? That is, there is no memory protection, but the compiler will only compile programs that can't access things that they are not supposed to. Only programs supplied by the system, or compiled by compilers supplied by the system, are allowed to run. (No downloading apps!) -- glen [Downloading? This was the 1960s. The security issue was about making sure that backups kept the security info intact, and you couldn't install a bad program by loading it from a fake backup tape. -John]
