alexh wrote:The problem associated with decapping old chips and turning them into verilog is that they used lots of "nasty" tricks which cannot be directly implemented in an FPGA today. The circuits have to be interpreted and somewhat re-designed. It is essential that the decapping take place but it is not a 1:1 copy what is there process.

ijor wrote:Forgot to comment about that. I am not fan of the fund raising of these kind of projects. The decapping cost is affordable (I paid a a couple from my own pocket), and some people have the equipment to do it for free.
ijor wrote: Then of course that it takes an amazing amount of time to do the actual reverse engineering. But that's "just time".

Locutus73 wrote:It was my understanding that decapping was very expensive and required non domestic high-specialized equipment. I mean, software development, even the most qualified and refined, can be done at home and good developers are not a rare resource in the retro community (mostly nerd and geeks like us ). I believed that decapping skilled people with access to the needed equipment was rarer and that decapping skilled people loving retrocomputing/gaming and with access to the needed equipment maybe was extremely esoteric. But I might be wrong.
