I have one comment about the rash of PDP postings on this and other newgroups. (I realize this is not strictly topical to Minix, but here it is): LSX. Heard of it? With all of the talk about the 11/34 and V6,V7, 11/70, etc..., I thought that LSX should be recalled. LSX ran on a PDP11/03 (LSI11) with 20-28Kwords of memory, no swapping, and a floppy or two. (It also had things like contiguous files, etc...) It only had one or two processes, but it could run cc, nroff, vi, and many other things. There was an article about it in the Bell Tech Journal a long time ago. Myself, I am writing a Unix clone (not Minix port) for the 6809-based Radio Shack Color Computer III, and before anyone flames about 8-bit processors, the COCO can address 512K of memory with its built-in MMU, and runs OS9 with ten or more processes just fine. If I didn't want the experience of designing a kernel, I'd just port Minix; the 6809, with four 16-bit registers in addition to the PC and SP, and with almost PDP-level addressing flexibility, could certainly run Minix as well as a PC. - Avi Freedman freedman@euclid.math.temple.edu
