It certainly isn't in the same class as Xenix/286. It stays up for months at a time. It is in the same class as V7. Coherent doesn't have virtual memory. It does have swapping. Therefore, you are not limited to what will fit in your system's RAM. BTW, small model in Coherent is the same address space size as a PDP-11. It (Coherent) has i/d space and shared text segments. It's no toy. uEmacs (GNU, no?) fits. So does elvis (a vi clone). Awk works (with bugs, not the same bugs as on SV3.2.2, but bugs). Awk does FP calculations with no FP chip. Good for the thrifty. Cron works, no observed bugs. Can one say the same of Xenix/286? > >What it does have is a uucp that works. It fits in roughly 10Mb of >disk space fairly easily. Yacc/lex/other development tools (keep >that small model compiler in mind, though). It was easy to port Berkeley Mail, smail2.5, and Deliver2.0. UUCP mostly works, but has minor warts.

It looks like Coherent will do most everything that V7 would do. That's a quite reasonable amount. The support for Minix is the net, the sources, and the book. Support from PH? :-) Cnews will fit. Pathalias will not as written. When folks have megabytes of memory, they fit the algorithm to the size. When they don't, they use another algorithm (or send the product back :-). BTW, the smail2.5 as ported uses a minimal paths file with a smart host. Hand edited, no big deal. Probably better than keeping a 900kb paths file around, anyway. It's more than Minix, and less. No sources for utilities or system. But the Minix stuff can be ported to it, and it's fun to do. It's a fair bit faster than Minix. Elvis was up and running less than an hour after unsharing the stuff from alt.sources. >BTW, we bought it. And sent it back. And got your dough back, too. With no hassle? We bought it, too. And kept it. Also the drivers kit, with sources for drivers. The price is right, and the manual alone is worth the money. If you want to run pathalias out of the box on the full maps, don't buy Coherent to do it. You'll be disappointed. If you want an inexpensive system that is fast and capable of doing interesting things, then buy it or not. We run an archive server for Coherent stuff. For the fun of it. echo "help"|mail uunet!sceard!farfel!archive-server to get started. farfel is a system that cost less than $1K. Including the OS. And the modem. And the 40Mb disk. I was thinking of using a Sun 4/whatever with 4Gb of disk and 24Mb of RAM, but I couldn't find one for less than $1K. This posting should not be construed to indicate that the poster does not have great respect for the various and sundry folk who brought out Xenix/286 SV3.2.2, and Sun4/whatevers. It may be taken as read that I miss the small is real good and let's use little tools all piped together attitude of V7. Disclaimer: I'm a satisfied user, nothing more. Your mileage may vary. Read the manual first. Don't believe everything you read, this included. -- Mike Murphy Sceard Systems, Inc. 544 South Pacific St. San Marcos, CA 92069 mrm@Sceard.COM {hp-sdd,nosc,ucsd,uunet}!sceard!mrm +1 619 471 0655
