Subject: Internal Supra (2400zi) bogging down my system!
Date: 21 Jan 93 12:26:08 EST
Organization: Bakers Field BBS

Here's some background...

I'm running a CNET BBS (2.42e registered) on a 2000 with a GVP 22mhz '030 Combo
board with SCSI controller and 5megs of 32bit FAST RAM on it.  The 2000 has 1mg
of CHIP RAM.  I've also got a GVP IO Extender board installed to give me two
more serial ports.

I've got a 14.4k Courier HST on the main serial port, a SupraFAX v.32bis on one
of the IO boards serial port, and a direct serial link to a 386 PC on the other
IO board serial port.  With this setup (2 phone lines) everything works fine. 
People can be on both modems doing transfers at high speeds and a high speed
transfer (9600bd or even 19.2k) can be occurring to/from the PC at the same
time.

We just added a third phone line two weeks ago, and hooked it up to an internal
Supra 2400zi (plain 2400bd) modem.  Whenever someone logs onto this line, there
is a MAJOR slowdown throughout the whole system.  Transfers to/from the PC
always abort and my own console (sysop) slows down.

Any idea why this is?  The driver software for the Supra (modem0.device) is
version 2.5 I believe.  Oh, I also have another unused Supra 2400zi sitting in
another internal slot... but we're not using it so I assume it's not affecting
anything.

Why would the use of the 2400bd modem be slowing everything down?  Is it that
the main bus is becoming too busy, or is it a problem with the modem.  I guess
I could try using the other unused modem for a while...

Subject: Amiga monitor 1080 on a '286 at-clone?
Date: 27 Jan 93 14:12:08 GMT
Organization: Unisys Corporation, Tredyffrin

Can an Amiga monitor (model 1080) be used on a '286?  I know the answer is
'yes'.   I have already done the simple connection of my CGA card's composite
out to the composite in of the 1080.  But can this monitor go beyond that, and
how far beyond - EGA, VGA?  If it can do either of these, I'd like to know
details of how to configure it.  This monitor is on loan and I'd hate to
blow it up.

Also, if it can only do CGA, would a RGB connection be much better than my
composite connection?  Can I use a standard CGA RGB cable?  How would I set
the RGB switch on the 1080 - options being analog or digital(pos. or neg.)?

Thanks for any help.

  I don't think you can find the 1200 for cheaper than $599 without a HD,
I may be mistaken.  I don't think that's expensive at all for what you get,
and $849 with a 40 meg HD is pretty good.  The retail price of the 4000 has
been lowered to $2700 but that's how much the local dealers have been selling
them over here for since its arrrival... so maybe they are just lowering the
retail to what they REALLY cost.

I ran my A2500 for over seven months using both a GVP Series II
[200Mb SCSI] and a 2090A controller with two ST506 HD's on it.
The only problem I think I had was overloading the power supply
by running three HD's and five expansion cards [including 68030
accellerator card]. When I disabled one of the ST506 drives that
was giving me some problems, everything worked fine.

Using GVP's FAAAAAAAASTprep, change the BOOT PRIORITY on your
SCSI drive to be more than the boot priority on the 2090a drive.

I did this and my machine booted great from the SCSI board. And
when I pulled the SCSI board out to put it in my A4000, the 2090a
drive booted fine. 

Should be a piece of cake.

I tried a Western Digital 212Mb HD and got nowhere. I think the A3001 board
can only cope with 40Mb and 80Mb Quantum drives. 

Get a decent SCSI controller. That's what I did.

      Ahem!  Please read before you post.  I did try AC Tech.  (Amazing Tech =
Amazing Computing (AC) Tech).  Telling me where to go won't help at all.  I
want info from someone who's actually got the thing to work.  I also would like
information on programming the glove in High Resolution mode.  I have found that
most of the people who have written powerglove programs don't take into account
accelerators.  The AC Hack only works in 68000 mode for me and flat out bombs
on my 68040.  I need to program it to work as a background task with my 68040
as I am using the glove to perform 3-d manipulations.  I also don't want just
UDLR-button info but X,Y,Z,rot,fingers which you only get from hires.  To be
more specific, I want timings on sending receiving signals to/from the glove
and any specifications on hires mode available.  I already have built the
joystick interface (port 2) and I have built the parallel port interface to
the glove.  I will most likely end up using the parallel port because it's
more reliable than using the joystick port (like in the AC Hack).

P.S.  John, this isn't really a flame.  I'm just disappointed that the only
"help" I've gotten are people telling me to do something I've already done that
doesn't work.

Sorry, I can't help you with your Ram problem, But I'd like to mention that
you should watch out for Briwall!!!  I had a problem with something I had
ordered...they said, "No Problem, Just send it back COLLECT and well pay for
the shipping and get your problem fixed."  A couple of month later I start
getting bills from the courier saying that Briwall never paid them and they
want $55 from ME!  After MONTHS of complaining and tons of phone calls to
Briwall, they STILL didn't pay for the courier.  Finally the bill went to a
collection agency and I HAD to pay it.  Needless to say, I will NEVER buy
anything from Briwall ever again.

BE CAREFULL WHEN PURCHASING FROM BRIWALL!!!!!!!!!!!!!!!!!!!!!!!!

Hi all. I have a question- I have looked far and near for a High Density
floppy for my amiga 1200.  I know applied eng. used to make them, but they
were not 'standard' hd formats; and they wouldn't read MeSsy Dos HD's...
is there a company out there making external high densities ??? please note
the 1200 uses the same externals that can be used w/ 500/2000, etc.........

IF NOT, then is there a hack to use an A4000 replacement drive externally??
The 4000 drive is exactly what I need for MS-dos xfers...

	Sounds reasonable, but who knows if it's true.  I'd expect
such a beast to include the DSP, but it might not be usable for
a while (until 3.1 is out).

	This is just bringing the machine's retail price in line
with it's street price.  My local dealer is selling the A4000
Power-Up package for $2593, if I remember correctly.

	I have recently aquired a very old Mac 3.5" drive with, not a 25-pin

Date: 21 Jan 93 16:02:53 GMT
Organization: University of Rochester, Rochester NY

I need a graphics board for the A3000UX here at work.  We have a
Sony Trinitron CPD-1302, and a lot of the real estate just isn't
being used by the Unix side.  Plus, we want color on the Unix side,
and more than the standard number on the AmigaDos side.

I've gotten two tips.  One is that GfxBase makes a good board, 
called GDA-1 (or GDA-2 if you get 2 Meg of on-board RAM instead of 1),
but they don't have a driver for the Unix side.  Dale at GfxBase
tells me that as soon as they come out with one, it'll be free to 
people who've already bought the board.

I'm also told that Commodore has a board, but I'm not sure on 
details.  Is it the A2410?  Someone mentioned the "Tiga" board?
I imagine this has Unix side drivers.

What I'm looking for is information and advice.  Can people tell
me of their experiences with these and/or any other boards?  Before
investing several hundred dollars I'd like to know what I'm in for.

Posting or e-mail are fine.  Thanks.

That makes me wonder if this has to do with my serial port problems. I have a
68030-33 without any 32 bit RAM (I wait to install it until I get the fan I
ordered), but with 1MB Chip and 8MB Fast. Using my Supra modem at full speed
works really great since I have the 030. The system doesn't slow down a whole
lot even at full speed and my cps rate has gone up considerably. However! When
I write something to a PC disk with Cross DOS or my module player in the
background switches it's modules I have a pretty good chance of getting
transmission errors. Could it be that the 030 is being really wasteful with
the Chip RAM bus and even though the CPU isn't slowed down I get problem with
my serial port due to an overloaded chip bus? Oh... interlace and high color
screens are also a pretty bad idea when doing file transmissions. A friend
of mine with a Supra modem, but "only" an AdSpeed (14MHZ 68000) doesn't seem
to have any of these problems although my computer outperforms his in terms of
benchmarking software.

Let me know if there is some truth to this. How could I fix the problem? I
guess the 32 Bit Fast RAM won't help in this case. It might even make it worse,
because access to Chip RAM will be more intense (less time will be spend in
executing programs in the faster 32 Bit RAM). BTW, my KS ROM is mapped in the
512KB SRAM I have on my accelerator board.

I have posted on this subject several times, and I am just about ready to trash
my A2000HD.  The problem is this:

  I have been having inexplainable system crashes for about a year now.  The
  guru's are usually something like 8000 0004.  The crashing usually begins
  about 30mins. after I first boot up and then continues at random.  I have
  had the system crash in TERM (all versions), JRCOMM, MultiPlot, and every
  other program I have (even during bootup, sometimes...)

  I am running 2.04 (it crashed before I upgraded from 1.3 as well).  I have a
  2091 HD Controller/40 Mbyte Quantum.  I use Toolmanager2.0, NickPrefs,
  DirWork1.62?, FracBlank, and the above mentioned progs.  I have a 2088
  bridgeboard as well (using older Janus software), although I have tried
  leaving out the binddrivers command in my startup and it makes no difference,
  as far as the crashing goes... I have even tried using the system after
  booting up from the original WB disks to no avail. (Which is what makes me
  want to believe it is a hardware problem...)

  I have taken my machine to the nearest service center and they said that
  they ran a complete diagnostic and couldn't find a thing wrong with the
  thing.  (Of course I told them that it takes it awhile sometimes and to let
  it go awhile, but I doubt they let it go long enough.... personally, I don't
  think that they knew what they were doing...)  I have 2 MEG of memory on the
  2091 card and all memory test say that the mem. checks out.  I have used both
  the program that comes w/the 2091 as well as the PD MemCheck program. 

  Would someone please help me with this?  I desperately need my machine to do
  school work.  Not to mention the fact that a guru every min. when you are
  trying to do anything is VERY annoying.  Any help is GREATLY appreciated.  I
  have seen a few other people w/the same prob, and we would really like to
  have control of our machines again....    HELP!
