Asking for a friend. Does Coherent (the $99.95 version) have or support AWK? Are GNU EMACS and other GNoodies ported to same. Any big red flags we should be concerned about? For such a price, it seems like quite a bargain if it supports the tools.... Post or reply by E-mail. If response is interesting I will summarize here. Thanks in advance. -- Chip Morris, Senior Engineer Software Options, Inc., 22 Hilliard St., Cambridge MA 02138 (617) 497-5054 chip@soi.com

Very interesting to see Coherent mentioned here. I just saw the ad for it in PC Mag (9/11 issue). This is a $99.95 software product that compares itself to something selling for $1,495! In the same issue of PC Mag there is an article on DOS partitions, and it mentions that 4.01 users could be endangered if they add certain "XENIX" type OS's which put some erroneous info into the FAT. I wonder if Coherent would cause that problem. Ad for Coherent mentioned that its users will be able to access news and files via UUCP. This is a product I definitely want to learn more about. -- NEIL PARKS Domain routing: ac119@cleveland.freenet.edu Bang routing: uunet!ncoast!skybridge!cleveland.freenet.edu!ac119 Fidonet: 157/511 (Appleholics) GT: 27/0 (Tardis) "Competition is the backbone of the American free enterprise system."

Coherent does *not* have virtual memory... you are limited to what will fit into your system's RAM. Coherent is compiled with small model... 64k text and data. This rules out *any* of the GNU software. Coherent does not have a C compiler that supports any other models. I'm not sure that you can run news on it. Maybe C news, if the shell is up to it. 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). In other words, MWC is comparing itself against a product that does *much* more. Faster? You bet, especially since you don't have to take virtual memory into account. It's roughly the same as Minix, without the source code and support that Minix has. BTW, we bought it. And sent it back.

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. Porting Berkeley UUCP shouldn't be too much pain. > >In other words, MWC is comparing itself against a product that does >*much* more. Faster?

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.
