news@tcr.UUCP (John B. Sobernheim) (01/10/91)
I have seen the light and it is called /usr/amiga/bin/fractal We received a 3000UX the other day. As far as I know this is a saleable unit (I am a dealer), one of the first. The following are my impressions of the machine so far. The Amiga 3000UX that we received is configured with 9 MB's of RAM, 1MB of Chip and 8MB's of Fast (using 1mbitx4 zips). It has a 200MB Hard Drive. The Ethernet Board was also included and installed. (From the brochure my dad got at Comdex, I had thought the Ethernet board would be an optional pheripheral). It comes with three manuals; Installing Amiga UNIX, Learning Amiga UNIX, and, Using Amiga UNIX. Unix. There is a short command reference manual included. There is a single page saying that this is a BETA release of the software and manuals and that the user is eligible for a free upgrade to version 1.0 of the software and manuals (For a $50.00 media replacement/shipping and handling charge :-). The version of Unix in this A3000UX was BETA 3j. An errata page listing known bugs and problems was also included. Finally, there were two 3.5" floppy disks (3000UX Boot & Root File System) and an install tape cartridge as well as the standard Amiga software and manuals. The system was preloaded with Unix. I set up the system with a 1950 Color Monitor and the A2232 multiple serial port card. By holding down both mouse buttons on boot, I was able to boot into AmigaDos 1.3 and 2.0. The Work: partition was set up as a circa 21MB partition. By rebooting the machine without holding down the mouse buttons, it booted into Unix. (On the first boot, it went through a configuration script asking about network setup, passwords, etc. I was absent through this procedure). When it got to the login prompt, I logged in as root, and used the SYSADM (Similar to FACE on 3.2x Unix) interface to add a new user and home directory called tcr. It created a /home/tcr directory and set up ksh as the default shell. First thing I did, as tcr, was lock up the console :-). I tried, and succeeded, to run Xwindows, but I forgot that I needed some sort of interface to it, ie. Xterm, Open Look, etc. After TURNING OFF THE POWER and going through a palm sweating fsck on reboot, I read the manual a little and found that we have virtual terminals in Amiga Unix. If you hit left-alternate-F1_through_F8, you can have eight (or ten, depending on how you configure it) virtual terminals into Amiga Unix. When I locked up the one virtual terminal by trying to run X, all I should of done was log in under another virtual terminal (left-alt-F2) and kill the task. Live and learn. Shortly after this, I found (by reading the manual) a script called oladduser which added all the stuff to my home directory and set up paths to allow me to run Open Look. I got Open Look up and spent the rest of the day, trying to get it up in more than one bit-plane. I was not successful. (If anyone knows what I need to do please mail me!) A couple of decent tech/unix guys came in and we all played with the machine some more. I asked them about my problems with X and they said, "right" :-). We found a neat thing in SysVR.4 where when doing a 'ls -al' it now shows links in the format of file -> file. (file [is linked to] file). There are a large number of man pages included in the installation, a variety of games including nethack and adventure in /usr/games, amiga specific files in /usr/amiga, troff, gcc and cc. The default $PATH doesn't seem to include the users current directory, which is interesting. (I think it has to do with /etc/profile and /usr/bin/ksh. ie. In /etc/ profile it says something like if shell is rsh or csh, do this, it doesn't do it if shell is ksh. Anyway I haven't gotten around to checking that out). I compiled hello.c with gcc and cc. A customer came in and we stuck a #pragma in to see if gcc would try and invoke nethack or something, it didn't appear to. Another customer found a man page for nawk (new Awk) but couldn't find the program itself. There is a spreadsheet included in the distribution. News software is included in the distribution, I didn't check to see what other communications software was included... kermit, umodem, etc. We played around with tty monitors and servers and got a login prompt out to a 2500 running vt100. My UnixPC, that's on the net, is all the way on the other side of the store and I haven't gotten up on it yet. /etc/ inittab has entries for the built in serial port and the A2232 multiple serial port card. The built in serial port is referred to as /dev/term/ser. /etc/inittab also has entries for all of the virtual screens calling a program called /usr/amiga/bin/getscr as the "getty". All this time I hadn't seen a single color other than the standard console screen of 640x200xblackxgold, the F2 - F8 Screens of varying resolutions and colors (ie. F5 is 640x400xblackxwhite) and the Open Look screen of 640x400xblackxwhite. A half hour after the store closed last night I ran it... /usr/amiga/bin/fractal. Ahhhhhhhhhhhhhhhhhh! It is an Amiga. :-) There is a device called /dev/amiga that let's the developer access the Amiga's Hardware, I think.. the manual warns about it's usage however. Anyway, I hope this serves to whet ya'lls collective appetites. Any questions/problems I can help with, please mail me. If anyone would like, I can post files like /etc/inittab, directories, etc. -- John Sobernheim ...boulder!tcr!news || news@tcr.UUCP The Computer Room ...CIS 76625,1210 Denver, Colorado ...But moma, that's where the fun is!

Sounds Cool, I just want to know a few "general" things. 1) How much are these things? I hear $5000 (seems cheap) 2) exactly "what" are you supposed to do with UNIX? ie. what's the "market", schools? CS majors?, busineses? 3) If i had one how many Dumb terminials could i hook up? 4) How UNIXish is it, does it turn ya amiga into a "Mini-frame" 5) Whens it comming out for my 500.... :^) (Kidding) Sounds Cool, if i win the lottery tomorrow I'd buy one. and a regular 3000 for a terminal!. . -- yorkw@ecn.purdue.edu Willis F York ---------------------------------------------- Macintosh...

SYSVR4 (according to AT&T), lets you create either SYSV file partitions, OR BSD FFS partitions. Yes, those are called "Fast File System" partitions (in this case, it has no reference to Amiga's FFS) The BSD stuff is considerably faster than SYSV partitions.... Besides the fact that you get 255 char filenames, soft links, hard links, etc. (Try "mv" on a directory, I'd like to see if that works - It should... under SYSVR3.x it doesn't!) :Richard E.

The "neat thing" isn't that "ls -al" does something different, it's that S5R4 supports symbolic links; hard links should be shown the way they always have been. (BSD shows symbolic links the same way.)

The short answer for the Commodore 64 equipment is that its probably not worth
keeping. Finding a market for it is not very likely, but you can always try
places like misc.marketplace.computers (I think that's the newsgroup).
The long answer is that an AmigaUX should be bootable under AmigaDOS and there
is a Commodore 64 emulator for AmigaDOS (ReadySoft software). The emulator is
pretty good, but by no means great. There is also an interface for hooking up
a 64 disk drive. Many pieces of 64 productivity software seem to work with
it, but most games have trouble (some work, some don't, some do and don't).
Disk copy protection (which most games have) is a little more than it can
handle. This emulator takes over the Amiga, worked with AmigaDOS 1.3 (don't
know about AmigaDOS 2.0), and operated at about 85%-90% speed (at best). For
trying to make two different architectures work together, it was a really good
effort (there were just limitations that had to be lived with).

Given that S5R4 has a BSD-style "rename()" call, one would hope it works; that presumes that AT&T fixed "mv" not to waste its time with "/usr/lib/mv_dir" and just use "rename" to move stuff (including directories).

Commodore is clearly avoiding telling us how much they plan to sell the machine for in this newsgroup. Someone asks Can it run on the 2500/020, how much it costs, and when it can be had. The response from CBM is that the 020 board was designed to allow unix to run. No response to the price or availability issue. The only thing I hear about is the 3000 and beta versions for developers. Nothing about whether you can get even a beta version for the 2500/020 or 2500/030.

It will run on both the 2500/030 and 2500/020, you will by able to buy it for your existing machine. I think the CBM people on this group may not know or may not be at liberty to say how much the software alone will cost. As far as I know the software hasn't even been announced as an add on for existing Amiga w/ MMU systems, so it is not unreasonable for a CBM employee not to quote you a price. It is very possible that a price hasn't even been set yet! I don't have a clue what they will charge for the software, but I do know that the odds are it will be distributed via tape, so you will need to own/rent/borrow a tape drive in order to purchase the software. -Jason- --------------------------------------------------------------------------- Jason Goldberg UUCP: ucsd!serene!cbmami!jason Del Mar, CA

It was my understanding that the A3000UX was still under beta-testing and
that we, the beta-testers and software development companies, could not
make public comments about it.
Is this no longer true?

Ok, if the machine and OS is now public, I guess I can comment for the
software developers point-of-view.
For a CISC processor version of UNIX which are suppose to be smaller than
their RISC counterparts, AMIX seems to be alittle bloated. On a 9Meg
system (8 fast, 1 chip), the UNIX when booted only leaves me with alittle
over 5Megs. This is before the X Window System.
I don't know if I agree not to put color into the console X server. The
reason I heard was about speed and I really don't fully believe it.
The OPEN LOOK window manager has some problems with window placements. I
don't think they are handling the USPosition and PPosition hints.
The X server has some major drawing problems if you interrupt it when it
is at work using the window manager (dragging a window while it is being
drawn).
I don't know what they are sync'ing the mouse pointer with for X, but it
is very unstable. I will venture a guess that it is not a sprite. 8^)
The good points are that it seems pretty complete as SVR4 goes. Besides
a major bug in the socket library (recvfrom () call) and the X problems,
it is pretty stable. NFS works like a charm, along with TCP/IP (this was
not the case for the earlier beta versions back 2-3 months ago with kernel
panics on NFS writes).
BTW - I use the gcc complier on the system, and not the standard cc for it
gives my much tighter code.

I will venture a guess that it is not a sprite. 8^) The speed of the pointer is faster in the current release. An Amiga sprite would not make a good pointer because it is low res. Sure, there are tricks to make it look high res but you lose precision. I agree the pointer could atleast be sync'd with beam. You are also able to make suggestions through the bug report channels. I've seen none on the mouse pointer. >The good points are that it seems pretty complete as SVR4 goes.

Reminder: Everyone who currently has Unix on their Amiga has a pre-release beta test version. Some of these people are beta testers who received the software and/or hardware by special arrangement, others are the lucky few who have managed to buy an A3000UX through a special educational program (and some mysterious early dealer units).

Truss is a system call tracer: $ mkdir one $ truss mv one two execve("/usr/bin/mv", 0xC07FFF00, 0xC07FFF10) argc = 3 open("/dev/zero", O_RDONLY, 0) = 3 getuid() = 0 [ 0 ] getuid() = 0 [ 0 ] getgid() = 0 [ 0 ] getgid() = 0 [ 0 ] close(3) = 0 lxstat(2, "one", 0x80004F28) = 0 lxstat(2, "two", 0x80004FB0) Err#2 ENOENT rename("one", "two") = 0 _exit(0) $ Yes, mv uses rename().

Only somewhat ``way cool''--truss has a set of compiled-in strings that it uses to resolve the arguments. The `-x' switch turns this feature off. (ie no symbolic processing is done and all arguments are displayed as hex digits). Pax, Keith

Truss knows what the arguments to system calls mean, and will fill in the #defines for them if it can. It even gets the bits right. This is from a truss of cu connecting to a serial port: alarm(10) = 0 open("/dev/term/ql01", O_RDWR|O_NDELAY, 0) = 5 alarm(0) = 10 Truss has many options which let you limit the calls being traced, follow forks, truss already running processes, and elaborate on the arguments to certain calls. $ truss -v ioctl date # be verbose about ioctl() execve("/usr/bin/date", 0xC07FFE60, 0xC07FFE68) argc = 1 open("/dev/zero", O_RDONLY, 0) = 3 getuid() = 0 [ 0 ] getuid() = 0 [ 0 ] getgid() = 0 [ 0 ] getgid() = 0 [ 0 ] close(3) = 0 brk(0x80006990) = 0 time() = 665688842 ioctl(1, TCGETA, 0xC07FFD28) = 0 1 iflag=0026406 oflag=0000005 cflag=0000277 lflag=0107073 line=0 cc: 003 034 010 025 004 000 000 000 2 Mon Feb 4 12:30:30 EST 1991 write(1, " M o n F e b 4 1".., 29) = 29 _exit(0) 1 - Note information about the TCGETA 2 - Note the real output from the date command, before truss shows the write call -- skrenta@amix.commodore.com
