I am in the process of building an A2000 motherboard, got loads of components on the way but I am in need of a Buster chip -01 or -02 for an amiga 2000 so if you have one for sale going spare please let me know
You need the 02 Buster. The 01 Buster prevents DMA cards from working (something that was fixed with the "Buster Tower"). The 01 Buster only shipped in the Rev 3.9 motherboards, maybe a few very early 4.1 boards.
The 02 Buster is available on eBay.
The issue with the ebay ones is they seem to be all in america, I am in UK and it works out very expensive with shipping. Hoping some one in europe has one lying around and can let it go for a fair price.
