apollo 4040 and A3000 scsi adaptor

[Whaka]

Hi,

i need some information about this adaptor supplied originally with the apollo 3040/60.

a friend need to test an apollo 4040, but didn't have a functionnal A4000 yet.
i can test it in my A3000, but an adaptor with a wire between the onboard A3000 scsi controller and kickstart is required to make it work.

it's very hard to find informations between wich pin it should be... by searching a bit, it seems the wire need to be on the pin 39 of the scsi controller. but i don't where it need to be on the kickstart.
someone have this information ?

many thanks

no, it's not the missing _INT2 signal, the motherboard is already fixed for that.
the problem is not the same.

when you don't have the adaptor supplied with the 3040, the internal scsi controller of the 3000 won't initialize at all.
so, you power on, the power led turn from low to full bright, and then... the boot process stop here.

have the same issue as aggro_mix, can't boot with scsi.device above 40.12.
useless to try with the 030, the hardware patch make the scsi unworkable with it.

there's some very old motherboard revisions,  rev 6 and maybe some of the first rev 7, wich are unable to reach KS screen if the internal scsi have no device connected.
the 3000 i used for testing the appolo is a rev 7 upgraded to 7.3 and can boot without any drive connected.
