I have developed an 8051 based microcontroller board that can execute 
complicated IEEE-488 command structures with ease.  As designed,  this board 
could be placed between your computer serial port or parallel port and the 
IEEE printers.  The parts cost of the design wirewrapped is approx. $125.
(If you are good with the bus interface for your computer the schematics
could be fairly easily modified to sit on the bus.)
I have put all the info from my design into a packet (including monitor 
and example routines).  I will send this to those interested for $10
to cover postage, copying, and disk (there is no profit in this for me).

Also,  I would be interested in a joint development to put this project on
a printed circuit board.  Some type of arrangement like splitting
development costs.

Subject: Non-aliasing SCSI board for IBM compatibles
Date: 27 Jul 92 22:14:24 GMT
Organization: Department of Physics and Astronomy, University of Iowa

Does there exist an SCSI adapter for IBM compatibles which doesn't do
sector aliasing?  I've got one now that does aliasing, but I'd like to
get one that doesn't alias so I could use a utility like SpinRite to
periodically reformat my drive (regular maintenence, you know).

I know such adapters do exist, because I have access to a computer that
has one about which SpinRite doesn't complain.  It's BIOS doesn't announce
itself on boot, and it's not my computer, so I haven't felt comfortable
ripping it open to see what's printed on the board.  I'm particularly
interested in the much heralded Adaptec 1542, but I'm interested in others
as well.

Send your replies to me by e-mail, and if I get more than, say, two replies
I'll summarize and post.  Thanks in advance.

Subject: IEEE Workshop on Imprecise and Approximate Computation
Summary: ****** Position Paper Due on Aug 15, 1992 ******
Organization: Computer Science Department, Texas A&M University
Date: Thu, 30 Jul 1992 01:37:30 GMT

				
			Call for Papers
 
	IEEE Workshop on Imprecise and Approximate Computation
 
			December 1, 1992
			Phoenix, Arizona

			Co-Sponsored by:
  	IEEE Computer Society TC on Real-Time Systems
		    Office of Naval Research
		      Texas A&M University



Imprecise computation appears to be a promising approach to providing 
scheduling flexibility and enhancing dependability in dynamic real-time 
systems. Over the years, several systems have made use of approximate 
computations in time-constrained situations. Recent work in this area has 
resulted in a formalization of the approach and focused on providing system
support for using imprecise computation. The potential applications of these 
ideas include both traditional and next-generation applications, such as 
intelligent control systems, machine vision, real-time databases, and highly
dependable real-time systems.

The purpose of this workshop is to bring together researchers and 
practitioners and provide a forum for discussing a wide range of related 
topics, including applications of imprecise and approximate computations,
reasoning about approximate results, approximate computation algorithms and
methods, as well as programming and system support, communication protocols,
and software development tools.

The workshop is held at the same location and one day before IEEE Real-Time
System Symposium, Dec 2 - Dec 5, 1992.

Prospective participants should send 6 copies of a position paper
(no more than 5 pages) by August 15, 1992 to Wei Zhao, Department of 
Computer Science, Texas A&M University, College Station, TX 77843-3112.
(409) 845-5098 (voice), (409) 847-8578 (fax); zhao@cs.tamu.edu. 

Complete details regarding the workshop will be sent to all participants
along with acceptance letters by October 16, 1992. Camera ready copies of
the papers will be due on November 6, 1992. All accepted papers will be 
published in workshop proceedings.

Organization: Software Development, Carnegie Mellon, Pittsburgh, PA

I have a Maxtor 4380 disk drive running with an OMTI 8641 ESDI
controller.  This runs fine at 33 sectors per track which is the formatting
done from debug G=C800:6.  Most of the references to the Maxtor 4380
I have found claim it will do 36 sectors per track (or better yet 19 sectors
of 1K each).  Does anyone have information on how to achieve this with
my controller (or do I need another controller)?  I would suspect this
is controlled by jumper settings on the drive and/or controller.  I would
also appreciate any documentation concerning the drive and controller
jumpers even if I can't get the extra capacity from my setup.

WAIT A MINUTE, don't let this thread fall into the email crack!  I wana hear
this.

I have been using a PC2A (I think) from National Instrument, a dead bang copy
of the orriginal IBM 488 card described in the PC Tech Ref Manuals.  I wrote
a 386 Xenix driver for some HP2608A printers.  Worked OK, but the board is
no good on the faster computers.  Now I'm kinda stuck, old driver not UNIX
3.2.4, old board no good either.  But I've still got half a dozen of these
printers.  Oh yes, you need to do secondary addressing for commands, this
is not a real simple interface.

If someone has a CHEAP solution, like a $300 board and some PD software to
begin the development process I am interested.

Thanks to several helpful replies, I WAS able to rescue all my data :-)    
The technique I finally decided to use was to disassemble the 3.5"  disks, 
allowing the inner sleeves to dry out.  Then I put them back together (Note: 
some of the snap tabs broke during disassembly, so I taped the two halves 
together. Also, I couldn't seem to put the spring and metal protective plate 
back in, so I just left them off) and copied off the data.  The first time I 
tried to copy the data, I got numerous "Abort, Retry, Ignore?" messages, so I 
tried again.  The second time, there were no such errors - I guess the disk 
needed some excercise to get aligned properly.  (The disks are now considered
unusable.)

The other emailed suggestion was to put the disks in an oven at low heat
(like 120 degrees F) to accelerate the drying process.  This process would
presumably not damage the disks.

Try the Verbatim group at kodak.  The ones who will recover your data if
it was on the Teflon coated disks... They could have a few ideas.

Another approach:

Drain water (optional spin dry -- outside the diskdrive), let them totally
dry semi-naturally (you could accelerate this some) and try and read them.
If you get errors that the drive can not correct, FREEZE the disks.  Don't
make the disks frozen popcicles, but very cold, and then try an read them
in your drive.

Can anyone say college physics' Currie point?

Subject: Re: SCSI vs. SCSI II Question
Distribution: usa

  There are two frequently used definitions of SCSI-II (maybe 3).  These are
    1) The command set, SCSI-II defines a superset of the original SCSI
       device commands.  You defiunately want a SCSI-II compatible
       host adapter.

    2) The data speed, SCSI-II  "Fast SCSI" defines a maximum data rate of
       20 MB/second.  If you have an ISA bus, don't even bother.  Furthermore
       few, if any, single disks (and none w/o internal cache) can meet this
       rate and the ISA bus won't even meet the 5 MB/sec of SCSI-I hardware.

    3) The data path, SCSI-I was 8-bit parallel I/O.  SCSI-II defines a 16
       data path.  This is useful, at least in terms of avoiding planned
       obscelecence (sp?).

    Thus, get a SCSI controller which is (1) SCSI-II command capable, (2)
implements the SCSI-II "wide SCSI" standard, and (3) has widespread driver
support.  I've had good luck with the WD 7000-FASST2 (which is only command
compatible, I think & has been sold off to Future Domain) and the Future
Domain 1680xxx (get the "M" version to allow cheaper cables to be used) as
ISA bus controllers.  For EISA, the AMI Fast Disk II (0-16MB cache, new
release to implement fast SCSI, currently wide... ) and the Mylex DCE-376
are both good, based on 1st hand experience.

   All SCSI-II controllers will accept SCSI-I devices (just like all 486's
run 8088 code and take 8 bit cards); however, SCSI-II devices can not
(generally) be used on a SCSI-I controller.

   Welcome to the blazing fast, under-standardized, highly-variable,
yet very flexible world of SCSI.  On the Mac it's a standard, on the PC it's
a tower of Babel.  Note that there are 3 or 4 driver standards, ASPI (adaptec
and clones - pick the clones), SDLP (WD, some Future Domain, all Columbia Data
drivers) Microsoft's LADDR (back when they were OS/2) and the least popular
ANSI standard (what does that tell you?).

Power is cheap.  Drive repairs are not.
Our lab equipment is never shut down.  We have almost no repairs.  (All the  
monitors however are equiped with dimmers, and every three months, I vacuum all  
the air filters.)

Even our 1.2 Gig drives are only drawing 50 watts or so, so that's order of a  
kilowatt hr/day.  So we're talking 6 cents per day, 2 bucks per month.  Cheap  
insurrence.

One other thing:  If possilbe set your system up where the temperature  
fluctuations are minimized.  (Basement.)  Temp fluctuations aren't good for  
socketed components.

I saw one MTBF ratings for drives.  A 10 degree difference cut the MTBF in  
half.  Keep them cool.
