An implementation with chips similar to the originals would probably cost an order of magnitude more. Which would mean the venture would not be financially viable.
Some of the challenges that would balloon the costs:
- Source ancient-tech components.
- Guarantee rights to reproduce the original board design.
- Make sure that everything works the same as the original, down to the tiniest quirk.
- Interface the ancient components with modern output ports.
- Do everything correct the first time (updates are not possible), or face hordes of angry customers.
- Do everything in a short timespan, or face hordes of angry crowdfunding supporters/customers.
