Hello, I'm considering buying some type of PC Clone system, for use under Unix. I've worked with workstations before, but never with a PC type of computer under unix. It appears, judging from the postings here, that the configuration, hardware & software choices for these beasts is far more complicated and perilous, than for, say, a Sun. Let me state what I'd really like: 1) A Decstation 3100. Unfortunately it costs way too much. 2) A sparcstation. Ditto. 3) A NeXT cube. Problems: CPU too slow (I'll be using this machine for heavy-duty numerical simulations, most probably, along with software development). Completely nonstandard window system. As you can see, I'll have to settle for a PC clone-type system. So now here come the questions: I want "real unix", which seems to rule out "Xenix" (I'm not exactly sure what it is, but it appears to be some heinous mutant strain), so that I can compile all sorts of nice net-goodies. Furthermore, I like Berkeley much better than AT&T stuff. There appear to be 4 Unix systems available: Dell, ESIX(?), ISC and SCO. (I've only seen advertisements for the last of these in magazines). What I want to know is how do each of these stack up for the following requirements: -- Development system. I.e. C compiler. Plain old pcc or something better (or worse!)? -- csh or ksh (both would be best) with job control. A simple SYSV bourne sh without JC is unacceptable. Or in the least, is there a public domain/gnuware version of the former that will compile right? -- TCP/IP networking for Ethernets. A necessity. -- File names >14 chars? (Very useful) Symbolic links? ditto. -- NFS?? -- Xwindows. A necessity. Do they come with anything more than the MIT stuff, e.g. OpenLook or Motif toolkits? I mean, of course, the _developer's_ version of same. -- GNU CC. Can I get it to work on the unices without alot of effort? (I.e. do they include an assembler that groks GCC output?) What is the cost for the above? (Unlimited users? Or limited?) What about support/upgrade costs? Next, comes hardware. It looks like I'll have to buy mail order generic clone hardware because of money (I'm a grad student), so I'd like to know what things are compatible with what. For instance: Disk controllers. Almost surely, I'd get an ESDI or SCSI disk for performance. Do the Unices mentioned above work with any "Computer Shopper"-type disk controller? Are there marked advantages of one over the other? Video display: This is my goal: a high-resolution (1024x768 or better) _gray scale_ display, preferably 17" or bigger. (I think the NeXT cube's display is fantastic.). I realize I may have to get a smaller monitor (14" appears to be the upper end before prices take a big leap), but I don't think that color will be that important. I've seen lots of ads for various types of "Super VGA" boards that claim 1024x768 pixels. Is this a standard in any way? How do the Xwindows do with these boards? Is it 1) a sure thing 2) Most likely 3) by no means assured that the X server supports the highest-resolution modes of these boards? How fast are they/with the X server? Are they all pretty much alike or are there big differences? And, what kind of monitor would I have to buy? (I'd like non-interlaced display if possible)? I.e. translate the ads for me---is a "VGA Paperwhite monitor -- $245" what I want? Lots of _color_ monitors advertise 1024x768 compatibility, but what about monchrome/gray scale? Please ignore my ignorance, but I'm new to the PC world (I have a severe brain allergy to MSDOS & the ilk) and don't really know what's going on. Please EMAIL responses to pa1159@sdcc13.ucsd.edu (post only if mail bounces). I'll summarize & post results. Matt Kennel pa1159@sdcc13.ucsd.edu
