Running a > shell, echoing arguments, that kinda thing? :-) :-) -- Begin war-story mode -- Some years ago, when I worked for Tandem, we shared offices with Tandem's Frankfurt network node. This machine ran well without too much difficulty with minimal memory, since it was mainly concerned with shuffling data buffers from one line to another. One day, the network manager came to me and said "we've just installed the latest and greatest version of Guardian on \NCEURO [the network machine], and I can't get it to boot. It just hangs." I went and had a look, and he was right. I took a dump and found that the machine had exactly 3 (three) pages (of 2048 bytes) of memory free after loading the kernel. Turned out that that was one too few: the system monitor (think: init) had paged its code space out before it had got around to enabling swapping. -- End war-story mode -- I think there are probably quite a few situations where this little memory would still work. I don't think I'd want to use it as an X workstation, though. Greg
