Most CV are malfunctioning these days. On the other hand, having a brand new CV would require a super expensive plastic case, in addition to a long development time. So in the meantime, why not to offer a simpler solution.
So it occurred me that we could have a brand new PCB to replace the original CV PCB. The idea is to keep the original CV case, but replace the PCB and front plate.
The new PCB would offer a series of improvements:
- All glue logic (74LS chips) replaced with single CPLD, leading to much improved reliability.
- Replace DIP components with SMD equivalents when possible (Z80, memories, resistors, capacitors, diodes)
- Replace TMS9928 with TMS9128, for reduced number of VRAM chips (2 instead of 8 )
- Remove RF and replace with modern audio/video outputs
I believe that can be done for under $100.
How about that? Something to think about next year and discuss with Coleco later this year. We have a deal for the CV2, so I suppose they wouldn't oppose to something like this either.
