Picked up a non working A4000T yesterday.  Was told it did not boot and they believed it to be a software harddrive issue.

Connected it to a 1080 monitor today and tried to boot it.  Floppy whirs, hard drive live flickers. CD light comes on sometimes, all the while I have a purple raster on the screen.

Eventually the screen goes dark and nothing.

Tried without 3.1 floppy and with it.

Looked inside, don't see anything burnt up and all looks clean.  Has a 68060 board with ram in it.  Noticed NO ram in the motherboard slots.  Does it need some to boot?  Only ram was on 68060 board.

They also have some Toaster 4000 card inside.

Before I go and pull the videotoaster card and reseat the 68060, any other advice for a newbie?

Does the purple raster tell me anything and then blank video afterwards?

Thanks

You need at least the 2mb of Chip RAM to be installed.  It is okay to have the other motherboard RAM removed and only use the RAM on the 060 accelerator card, but you must have the 2mb of Chip RAM installed (AFAIK).

I would remove all the expansion cards and hard drives first then reseat the kickstart chip.  

All you need is the cpu, chipram and the floppy.  If I remember correctly purple lines means the kickstart isnt executing properly.

No, kickstart is loaded from chips.
Just remove the zorro cards, reset the 060 card...should boot to insert workbench screen.

You will need a workbench disk with the 060 libs and the 040 fakea nd real libs.

Joining SACC is always a good idea. The members always help fellow amigians.

just copy the small 040lib and real 040lib and the 060lib to libs:
available on several sites aminet, etc

It might help to id the best 060lib for your board (phase5 or what?)

next meeting dec 5th (I think) check sacc.org or call chuck

all the four ram slots are empty on my A4000T yet I had 2mbs of chipram. (when it was working 7 years ago )

I guess I am thinking of the A4000D motherboard that has a 2mb Chip RAM simm and did not realize that the A4000T motherboard did not have a Chip RAM simm slot.

I sold my A4000T last year and did not open it up much while I had it.

Hi,

I would pull the video toaster, then I would leave the A4000 on for at least a half hour, then try rebooting. If the A4000 has been sitting for a while without being turned on, somethimes it has a hard time starting (at least mine does) after I leave it turned on for a while turn it off then turn it on, it starts right up. What mine usually does it shows me a purple stripe going vertically down the screen then goes black. After I leave it on for half an hour (or more) then turn it off, then back on it seems to take the purple stripe and then waves it, then turn I hear the familiar click of the hard drive looking for files.

This could only be my A4000, I really don't know.

Wow.. your A4000T is hard to turn on sometimes. You have to warm her up first

I do not think this is your booting problem but is something to consider when trying to boot from floppy when trying disconnecting drives to find your problem.
