opcode Posted February 26, 2012 Share Posted February 26, 2012 (edited) I had this idea last night, while I was sleeping. 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.
