Subject: HELP needed on STAR DP8480 printer ...???
Date: 9 Apr 92 16:01:02 GMT
Organization: Computing Services, Warwick University, UK

does anyone have any information whatsoever about the STAR DP8480 printer?
it was bought in a car boot sale for 5pounds recently.
it works ok (if the self-test is anything to go by), but had no cables
supplied with it, so we have no idea how to connect it to anything (and little
idea of how to control it properly once it is connected).(ultimately i
would like to connect it to an IBM PC; i'm assuming that with only 16 pins on
the input it will have to run on the serial port....? )
it has a 8*2 square-ish idc-type connector on the back, but no info at all.
any information at all, pinouts, control codes, (copies of (pages of)
manuals), address of company (though we have written to them asking for a copy
of the manual, with no response), would be recieved with much gratitude.
please e-mail me at

esuze@warwick.ac.uk

(please don't post to this group as i might not read it for a while)

many thanks in advance to anyone who helps, as i may not get round to thanking
people individually.

a million thanks,
bent double with anticipatory gratitude,

Ian

I'm curious.  I never see any postings about emulators in this newsgroup.  Is
that traffic somewhere else, or is it that emulator users don't post to the
USENET? :-)

You can see by my organization that I am biased -- I am a Sales Development
Engineer for Hewlett-Packard's Embedded Microprocessor Development Systems.
But I've been reading this group for years and haven't seen anything posted
about *any* emulators.

It all seems to be operating system stuff.

That's my opening to mention that Hewlett-Packard emulators do help to solve
problems in an RTOS environment.  I'll wait until asked to go into detail...

I started reading comp.realtime some two weeks ago. I use a Nohau-51 ICE
with 8051 family. i strongly feel an information exchange about emulators
( performance, price, tools real-time) will be appreciated.
Recently, I read an article (quoting from H.P. Mr. David B. Richey,
R&D /marketing manager of Logic Systems H.P.) stating as a rule of thumb
that for 32-bits ICE, accepted price is about 1000 dollars per MHz.
I lack the equivalent info (how much an ICE must cost?) for 16-bits.
If needed, I will be happy to contribute with my experience about Nohau; I
think however that my experience is very common.

Suppose you have to write a driver for a french X25 card named altitude and
you know absolutly nothing about realtime and nothing about Qnx.
That's my problem.
Does anyone know how much the writing of a driver on Qnx is different from
writing one on SYSVr3 like ISC or SCO ?
Another question is how much is it difficult to implement a full compatible
IPC (shared memory, msg queues, semaphores) of SYSVr3 on Qnx.

     In 1991 the Am29000 family was the biggest selling
     RISC  processor  family  in  the  embedded product
     business.  AMD wishes you to know that a very  low
     cost  evaluation package is available to you, ena-
     bling your company or institution to better under-
     stand  the  capabilities of RISC technology and in
     particular the Am29200 processor.

          The tool package is specially  configured  to
     deal  with  the  problem  of developing high level
     code for embedded applications.  The  use  of  GDB
     and  an  embedded  monitor provides an inexpensive
     method of developing software for complex embedded
     applications.   The  software  for  the evaluation
     package is free, and programs could be executed on
     a supplied 29K simulator.  Alternatively, an inex-
     pensive hardware platform is available for  proto-
     typing.   The  evaluation  board  is  not  of  the
     highest performance type, but it is  suitable  for
     studying  29K RISC technology, and it is an intro-
     duction to a family which offers members  of  much
     higher performance.

Keywords: 960, PSOS, EVCA960
Date: 9 Apr 92 15:21:11 GMT
Reply-To: dixon@crd.ge.com (walt dixon)
Organization: GE Corporate R&D Center


We're developing an application on two intel evca960 evaulation boards
running PSOS.  We need to pass data between these boards over a serial
link.  As a simple test we wrote polled i/o routines (More precisely we
cloned the serial I/O routines furnished in the Board Support Package.
When we run with the real time clock enabled (100 ticks per second),  we
intermittently lose characters (about 1 in 6) at 9600 baud.  Disabling the
RTC makes the problem disappear.  We have constructed a very simple test.
The communications task is the only program running on each board.  Our
ultimate application needs a RTC,  so disabling the clock is not a solution.

We have had a couple of go rounds with SCG tech support on this problem.
After almost three weeks,  SCG has said that this is a known problem; the
EVCA960 board is "too slow".

I believe that the problem lies inside a PSOS routine named TM_TICK.  SCG
stated that TM_TICK takes 4 microseconds. When really pushed,  they qualified
this time.  TM_TICK takes 4 microseconds when PSOS executes out of RAM.
PSOS is distributed in ROM, and SCG normally provides no documentation (at
least that I could find) on executing out of RAM.

SCG told us that they must disable all interrupts when communicating with
the host (over a serial link).  Since the original RTC clock ISR in
the board support package cleared ALL pending interrupts,  I am not
convinced that SCG had a real good understanding of the 960.

The EPROMS on the EVCA board are relatively slow.  The EPROM memory
region is configured for 20 some odd wait states.  Our polled serial
test sent characters
at 9600 baud.  We had roughly 1ms to read a character before it was lost.
Does it seem reasonable that running out of EPROM would increase the 4
microsecond time to almost a mille-second?

SCG has subsequently sent us documentation on executing out of RAM.  We plan
to make the necessary changes,  but it is important that we understand
what the problem is.

I'm not saying that such a restriction is wrong, only that you should
recognize them for what it are, punishments. Computer Center imposed
punishments should be minor (major punishments should require more
formality), imposed only after giving the user his or her say, subject
to appeal, etc.

I think your draft policy could be improved by separating the two
kinds of restrictions (restictions as minor punishment vs.
restrictions to prevent likely harm to the system or to people).

Without this separation, it is possible to punish users without due
process (in my opinion, this is exactly what happened at Ohio State
U.)

Despite the "rightness" and "wrongness" of logging these things, one
should consider the overall chilling effect of the monitoring. What
effect will it have on the users--and the institution--as a whole?

One might compare and contrast it to other forms of monitoring such as
license plate scans to see where you go, audit trails such as
recording your every command, etc.

It would be a good idea to study how these things affect the minds of
non-criminals, and weigh the overall effect with the security gained.

Not sure -- I'm not a lawyer, just a poor ol' student.  I would say, though,

IMHO, there is *nothing* that would give the ASS the right to act as he

I would mail YYAdmin and ask him to deal with it.

Raise a serious, serious stink.  See if XX can be fired, or censured, or
something.  Make his life hell (legally, of course).  It also depends on
what kind of program it is. . . If it's *illegal*, then I may be quiet, but
I think few programs are illegal to own, just to run. . .

BTW, on our system, it is illegal to *run* password crackers, but not
illegal to own them. . .

>	5)	What would you do in the YY admin's place?

I would do as I would have done if I thought anyone else from XX was
cracking on my machine.  I wouldn't mail XX's sysadmin, because he's the
culprit, so I would go to whomever is above him. . .

XX's actions are, IMHO, no different than the actions of any cracker I've
ever dealt with.  He had no right to access YY, and broke an account
somewhere else to get access to YY (and su'ing as root to A to get access to
YY as A is a crack, regardless of whom it's done by).

The ASShole should be burned at the stake, IMHO. . .
