Subject: Broken A2000 Power Supply...NEED HELP!!!
Date: 20 Aug 92 11:18:06 PST
Organization: BBS

                    A2000 POWER SUPPLY DONT WORK
 
 
    When I turn on system, sometimes the screen either is totally black
or keeps blinding in GRAY color.  The fan works fine.  I only had this
system for less than a year.  I bought this system used.  Since I have
2 A2000, I decided to test what cause the problem.  After a couple of hours
diagnosing, I figure out it was the power supply.  When I switch my other
system's (the working system) power supply to the non-working A2000, it
work.
 
    So I told the person who sold me system, he said,"the system is out
of warranty already.  Therefore, I wanted to fix it if possible.  I do
know about electronic stuff.
 
Description of the Power Supply:
 
-Made by TAIWAN LITON ELECTRONIC CO., LTD
-Input   120V, 4A 60Hz
-Output  5V/20.75A, 12V/8A
         -5V/0.3A, 12V/0.3A
-DC Output 200W
 
 
     If you have any suggestions or ideas on how to repair the
     power supply, or know where can I get one for a good price,
     or might know someone who wants sell his/her power supply,
     PLEASE LEAVE ME MAIL HERE.

This is correct.

They are confused.  With a ROM switcher bending pin 31 up and connecting it to
pin 21 *may* be needed to keep the two pin 31's from interfering with each
other.  But the ROMswitcher has to connect between pin 1 and 31 for this to
work on a rev 5.

Rev 6 requires no jumper.  If you have a ROM switcher, you may have to bend up
pin 31 and attach it to pin 21 though.  If the ROM came with a jumper from pin
1 to 31, it shouldn't need any connection and bending it up should be
sufficient.  But... if it doesn't work, make the 31 to 21 jumper.

If you think this is confusing... you should have had to figure it out!

I had a Star NX-1000C and it was the worst printer in my opinion that money can

This isn't really necessary.
I have a 16MHz A3000 witch is 'upgraded' to 25MHz *without* changing
the 68030 CPU. A 16MHz CPU is reliable also with 25MHz.
*My* Amiga works since about nearly two years without any problems.

I think it's saver to use a 16MHz CPU with 25MHz (a 16MHz 68030 *is* a
25MHz 68030, but only testet up to 16MHz), than to remove a SMD CPU.

Hello,

I have a A2000 with Board Rev 4.1 . The Computer works fine until I put
more than 1 cards in. With a 4Meg Ram Card all went fine. Adding
a second 2Meg Ram Card will cause strange GURU's after some well
worked minutes. The Gurus are so strange that I must switch off the Amiga
(no Keyboard Reset possible). Swapping the cards inside doesn't change
anything.

I've heard of some changes to Motherboards Rev4.x . Does anyone have
a collection of them ?

Thanks in advance


Ciao

BTW: the cards work properly together in another Amiga Rev6.x

  As I followed up with before and will mention again - they did finally

The Mega Midget Racer can handel upto a 50Mhz 030, and a 50Mhz 882. 33Mhz is
just the fastest that CSA sells them, but the MMR will take any speed 030
you can get, as long as you have the clock for it (the 882 must be as fast, or
faster than the 030.) Why is 50 the max? Well, that's the fastest that 
Motorolla makes.. Any 60Mhz systems probably use overclocking (A 50Mhz 030, 
being drive at 60Mhz with a 60Mhz clock.) Hope this clears things up a bit.

My personal experience doing this was quite rewarding and also
quite painstaking. I made a cable to hook up to my SCSI Tape
Backup. This was the painstaking part, that is, connecting a DB25
connector to a SCSI 50 pin cable that plugs (o)nto the host 
adapter on the drive. For pinouts see your GVP manual.

Aside from that all that is necessary is to set the ID on your
Drive and make sure that the terminating resistor pack is on your
last drive. Thiss is always socketed and is easy to move from drive
to drive.

Setup is a snap with the GVP software which will automatically
recognize the new drive once initially setup.

Have Fun ;)

    Not exactly.  The economics of the matter are a little more involved than 
this.  Motorola may have enough chips rated at a certain speed already, so it
is not unheard of to have parts which pass at higher clock tolerances be
marked at a lower speed rating.  However, it is never really known which chips
are of this type, and which are not, making any form of overclocking dubious
at best.
    In addition, Motorola is generally a bit more forgiving in its tolerance
specs than other manufacturers, which tends to lead to the phenomenon of people
trusting that almost all 680x0s can be overclocked.  Unfortunatly, this often
leads to anywhere from random problems with heat, to complete part failure in
more extreme cases.

	Ah, the wonderful mystery of the SCSI terminating resistors!  It
seems like every SCSI adaptor handles them differently.  GVP's controllers
definitely have some quirks.  Try taking the terminating resistors off and
rebooting.  I know some people with GVP Series II's for whom this has worked.

	Also, try giving GVP's BBS a call at 215-337-5815.  The sysop is
one of GVP's techies, and he has been very helpful to me in the past.
