Do it!!!! lolol              As I mentioned in the PS/2 Facebook group, it would be certainly possible,       with only a few (quite expensive) difficulties to overcome "somehow":       - I would need one fully functional card to take its 7 GAL logic chips off and       send them in for breaking their security mechanisms and read-out       - Demystifying the 7 GALs by my trusty contact requires around $ 2700 to be       spent, and I don't consider cancelling my pension plan for this alone       - A defect card would be *very* helpful to desolder almost all components to       get a clear view on the naked PCB for reverse engineering              I still don't know whether the PCB is 2- or 4-layered, and if there are traces       on the inner layers, which would make reverse engineering very hard.       Some detailed, high-res pictures would be required at an early stage.              I looked into the bill of materials, and it seems all components could still       be acquired, including the GPU, VRAM and RAMDAC.        Assembly would still be expensive from the pure manufacturing cost, probably       not under $ 500 for PCB and components.              My initial suggestion was doing some kind of crowdfunding to accomplish the       GAL copies, and then giving donors the opportunity to buy a card for the       manufacturing cost. Would still be like $ 500 per donation and $500 for the       card, so if that doesn't        raise any thumbs up, I fully understand. It's still a crazy venture.              In the end, it's only time and money, and I already volunteered for the time...              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
