I gather you have the 4-core version.
Looks like just dual core. I don't think the IBM 970ppc was ever quad core.
Sorry… I said “core” when I should have said “processor”. You have four processors...
Let's not split hairs.
In any case I have 4.18.11 doing its thing :

However upon reboot I seem to have lost a 2G dimm somewhere. I should
have noticed that on my last email.

Well hell. Sure enough Total RAM: 0x180000000 says 6G right there.
Weird ... I am looking into that. I simply pulled out the mem dimms and
gave them a once over with a pencil eraser and isopropyl alcohol and
then put them back into the slots in reverse order.
Yep .. oxidation on the pins I guess :
