   Adrian's digital basement released a video today showing off a number of things   
   including newly manufactured C64 motherboard pcb's.   
      
   I looked it up and found the site. Sold out of the UK. I'm ordering one.   
      
   https://www.tindie.com/products/bobsbits/sixtyclone-commodore-64-replica-pcbs/   
      
   Features below are from the website. Impressive that they even sell teh cap   
   kits and provide sources for replacement chips.   
      
   These are replica Printed Circuit Boards (PCBs) derived from the Commodore 64   
   8-bit computer.   
      
   The boards were created to allow Commodore 64 computers that had damaged or   
   faulty PCBs to be successfully repaired. This can be achieved by moving all   
   components from an original board to the replica board, or even replace some   
   parts with more modern alternatives.   
      
   We currently have 3 x replica board models available:   
      
       Assembly #250407   
       Assembly #250466   
       Assembly #250469   
      
   Assembly #250407   
      
   This board design was one of the earliest used by Commodore. It requires 8 x   
   8KB RAM ICs and many logic ICs as well as the commodore custom ICs:   
      
       6526 CIAs (2)   
       Basic, Kernal and Char ROMs   
       6510 Processor   
       PLA   
       6581 SID   
       VIC II Video Controller   
      
   Assembly #250466   
      
   This board was the last to be produced by Commodore that used the original set   
   of custom ICs:   
      
       6526 CIAs (2)   
       Basic, Kernal and Char ROMs   
       6510 Processor   
       PLA   
       6581 SID   
       VIC II Video Controller   
      
   This board tends to be more reliable due to requiring fewer logic ICs, but some   
   parts can be harder or more expensive to obtain (e.g MOS 8701 IC). The board   
   also uses 2 x 32KB RAM ICs as opposed to more common 8 x 8KB ICs.   
   Assembly #250469 "Short Board"   
      
   This board was one the last to be produced by Commodore and was quite a change   
   from the 2 earlier boards above. The entire board is a lot more narrow, giving   
   it the "Short Board" nickname. The custom ICs used in this board are:   
      
       6526 CIAs (2)   
       Basic ROM   
       Combined Kernal & Char ROM   
       8500 (6510 compatible) Processor   
       Custom 64-Pin PLA   
       SID (Later 8580 version!)   
       VIC II Video Controller (Later 8565 version!)   
      
   Some parts can be harder or more expensive to obtain (e.g MOS 8701, Custom PLA   
   etc.). The board also uses 2 x 32KB RAM ICs.   
   Other Information   
      
   Over the past 30+ years, there have been many boards that have become damaged   
   for various reasons such as poor storage conditions etc.   
      
   The replica boards are of the same dimensions of the originals and can   
   therefore be used as a direct replacement to the original PCBs.   
      
   Some improvements/modifications were made:   
      
   Improved silkscreen, adding more descriptive connector labels, IC names and   
   better placed component labels   
   Manufactured using modern PCB manufacturing techniques and materials.   
   Separate holes for R38 and it's accompanying capacitor so they no longer need   
   to be stacked on the 250407 board.   
      
   Prototype boards were tested with diagnostic software and harnesses to ensure   
   no issues were encountered.   
      
   A "Bill of Materials" community editable spreadsheet has been created to help   
   locating replacements parts: Click here to access.   
   Optional Extras   
      
   Some replacement components can be purchased along with the boards:   
      
   Resistor Packs, containing all required resistors for the specific model of   
   board selected. All resistors are high quality metal film resistors.   
   Electrolytic Capacitor Packs, containing all required Electrolytic capacitors   
   for the specific model of board selected. All Electrolytic Capacitors are high   
   quality branded products.   
   Resistor Networks, containing the resistor network components for the specific   
   model of board selected.   
   Other available component packs will be added as they become available.
