#Minor A3000 Problems
9 messages in this thread
Dan,
Unless something is really amiss somewhere in your 3000 your software
(system) clock problem is indeed an 8520 chip. I just went through a
similar situation and with the help of Don Curtis and several others I
tracked it down to an 8520. I was even sent an 8520 by a forum member who
is having mouse troubles and bought one to see if that was the problem.
Since he didn't need the 8520 he generously sent the chip to me. As soon
as I replace the correct 8520, the one with the TICK signal on it, my
system clock got well.
I also had a problem with my 2000 not booting unless the keyboard was
plugged in, that's not normal. I replaced the other 8520 and sure enough
the machine is back in working order again. Those chips are very static
sensitive so take care!

I solved my fast softclock problem by changing the 350 jumper on the mother
board. It was mis-set from the factory. Where is the quality control?
If I remember right, there was a related problem on early production 2000's
like mine (rev 4.2), where the hardware clock trimmer had never been set.

Dan,
Glad you found the problem with the clock. I'm with you WHERE is the
quality control. I've a 3 month old 2000 and alread the motherboard has
been replaced, the new board ate two 8520's, and I have to get a new mouse.
Quality control certainly isn't at the top of the list.

Hmmmm……
I have an Amiga 1000 that has never had anything at all repaired in it.
An Amiga2000HD that has never required any repair at all.
An Amiga2500/030 that had to have the Agnus chip replaced when it was new,
but has never required repair otherwise.
I cannot see any room for complaint about quality control.
(I also have six or seven older Commodore 8-bit machines, and none of them
had problems, either.)

I had to replace my 1000 when it was 2 weeks old. The floppy disk
connector doesn't seat tightly on the motherboard. I have to re-seat it
every 6 months. Other than that, it's worked great for 5 years. The SCSI
connector on the 3000 seats loosely, this will be more devastating when it
loosens up as it will probably trash the hard driev:(. er drive

Keith,
Sounds less like quality control, than some sort of lemon. It happens
in cars just like that. I have an A1000 and was using a 65meg expansion
drive with 1.5 meg. I have an A500 with the 512 expansion board. I have
an A2000 with 3 meg, 40meg HD, and an A2620 accelerator board. Out of all
that hardware, there was a 68000 chip in the A2000 that would not recognize
the A2620 board. $35.00 took care of that. It was out of warranty by the
time I added the A2620 board. Oh, and I have the A1000's original monitor.
It too hasn't given me any problems.
Am I lucky or were you unlucky? I have worse luck buying telephones,
answering machines, VCRs, and can openers than I have had with my
Commodores. If there was some sort of lemon law for computers like there
is for autos, you would win it. I think it would be appropriate to write
to the top management at customer service at Commodore with a list of the
things that have gone wrong with your A2000 in just 3 months. It might get
no attention, on the other hand, it might stir them up.
By the way, did you happen to buy mail order?

From the sound of your symptoms are you sure you didn't take some sort of
power line spike or lightning hit? When I see things like this, it seems
likely. Similar symptoms can be caused by plugging in or unplugging
printers, modems, joysticks, mice, or keyboards with the power ON. In many
cases this can be confirmed by finding burn marks on the connectors.

Speaking of which, I had to completely dissamble and re-assemble my 3000.
One of the things wrong was a capacitor that was mis-grabbed (you could see
the mangeled lead) and one end was not connected. I wrote a letter to CBM
about this and other QC items I found in the case construction.
