In our exploratory research we came upon an australian design from the late 70s which i think would prove highly amenable to the goals of our project.

Attached is a bill of materials along with other errata from a fellow peer's construction of the DREAM6800 computer in 2019.

I am having difficulty sourcing parts. I laboriously inputted and was able to locate every part on aliexpress, but multiple items from the same vendor would not cause a saving in the postage.

Does anyone know a more equitable method of sourcing the parts listed in this PDF?

Much appreciated.
