I think we can say that at least your CPU is working (the blinkingI even checked with a meter with 4.5 to 5 volts;same on KSrom. It's
power LED).
pin#31 on both chips. So, who signals the CPU to do its jmp start
vector? KSrom was swapped to a good one-- no change. BTW, this A2K was
Well, I would like to determine a component/device first. Let's look at that CTRL+(L)Amiga+(R)Amiga. What's the eletrical equivalent of these keystrokes? How is a reset carried out by a device. When I turn on the
A2K, what events & devices actually tell KS to jump to Startup?
CIAs around (there are two) didn't change anything. Normal is to read a one flash 'caps lock' light at startup and I get that. I'll check this
one out after shut down.=:D
I was there the other night and could not find their repair policy;
read it a long time ago. They may have dropped the service! Oops, time
is not looking good for the old Amigas.
Hi,...
The CPU, AFAIK, starts reading from zero on whatever it is connected to,...
so it effectively control itself.

The reset is by software, at least on the keyboard controller side....
Hence, it's the power LED you want to see blink when you reset by C-A-A.
If it doesn't blink the problem is in the area of the CPU (when my
original CS-PPC died, the LED never blinked and acted the same whether
the 4000 had the failed CPU card installed or not at all!).
It's the power LED you want to see flash. Even a perpetual guru would be
a start :)
If you determine that the fault is on the motherboard, and everything
else is fine, get another 2000. They go for very little on eBay. You can even then sell the broken one to get some money back (people will buy
any old crap on eBay ;-)

Right now, I'm not getting no reset or any change in the power LED.
It seems to me that a hardware RESET causes the power LED change. That's
the circuit that needs checking.

=:o "...perpetual guru..."! Actually the KS bootup screen qualifies with
it's graphical perpetual floppy disk going in the drive. I'm trying
to get to that point! It's CPU or it Set/Reset circuit with new KSrom.

The A2K we're dicussing came from E-Bay for exactly that purpose - backup! >Since my PPS ZEUS won't upgrade to OS3.1, so the backup was used. Worked
damn good for about a year+. :)
I trying to decide which system to continue with KS2.05 & WB2.1 or KS3.1 & >OS3.9. Which is the more classical?
The AmigaOne is setup for OS3.1. I fiddled the Emergency-Disks Startups
to boot the CDs either OS3.5 or OS3.9 in UAE. :) So, I not a crisis of
being without an Amiga. Now that's poor when your Amigaless! =:o
I would like to spend time & resources on AmigaOne. That's why I got it!!
Can you recommend a SCSI contoller for the A1. They're not cheap, but it's >difficult to determine what works with linux? Someone mentioned that even

The Frieden brothers are back talking in the AmigaWorld.net forums! OS4 is >just around the corner! They're short a graphic.libraries rewrite from >booting up OS4 on AmigaOne PPC native. Sounds good! :)
