Question
Kaizen
I've started to do a 1:1 reproduction of the TKG4 2 layer board set. The PCB Gerber files will be made open source for anyone that wants to get the boards fabricated through their preferred board house (I use JLCPCB) and assemble it themselves (or pay someone else to if you don't have the skills). The cost of the PCB and components would amount to around the same cost as an original PCB delivered to Australia (if you can find one) so there's no commercial viability in it and I'm pretty sure there may be copyright issues if sold commercially. I have a CPU board set that has track rot on the top layer (TKG4-14-CPU) which is my primary reason for doing it and I most likely just do the CPU board first and test/debug before moving onto the video PCB.
The PCB has been stripped and scanned, all component locations have been measured from the original PCB to ensure accuracy to within about 0.5mm.

I've started to layout the components on the PCB, the footprints/silkscreen layer needs to be created/edited to match the components on the original PCB (this is taking a considerable amount of time) then each component has it's X-Y coordinates measured before placing it on the board. 270 components have been placed so far with about another 150 caps to go as well as the pots and connectors then I can start laying out the tracks.
