CPU - I think it was the 900 series with a 20GB hard disk an an Intel Atom processor - N270; 1.19 M#/s. I gave up mining when GPUs came in - simply too busy to do all the work.
https://en.wikipedia.org/wiki/Asus_Eee_PCI appreciate the tip re. the forks. I was aware of BCH but not some of the others and Darkstar's website was nice.
Trying to find a block now is so difficult I have been hunting for one for some time I bought a bunch of older ASIC miners for the hunt just ended up with a "very" large electric bill.
I even rented like 20PH for 2 days and never managed to find a block.
I think bitcoin would have been better staying CPU/GPU they removed this from core a long time back now. Now you must be a slave to bitmain or others if you want to be in the mining game today.
This really is a fantastic story there are not many people here who have mined blocks way back then that managed to keep them until now.
