Re: Is it at all possible?

https://github.com/boelle/C64-Schematics-Boards/tree/master/From%20Programmer's%20Reference%20Guide

Eagle schematic should now be 99,99% the same as in the Programmer's
Reference Guide which if not mistaken is also what Rev A boards are made
from

There is also a txt with a link to the Google Sheet that holds the BOM.
Lines in RED are what i need to source.

3 pdf's there also, 2 are the schematics from Programmer's Reference Guide
and the last is the Programmer's Reference Guide itself it in its complete
form

A photo of the board sent to be by Santo, i will initial use this as a
template to make a replica of the Rev a board. in eagle i will simply
import the photo and place components on top of that. for the tracks i will
need a scrap board thou where i can remove all components so nothing is
hidden
