IBM 1410 FPGA Implementation Update - new github repository

I think this implementation would give definitive answers to some of the obscure corner cases which may not be well documented and thus may not be correctly emulated in software. So even if never implemented on an actual FPGA this is very valuable. My Desktop CYBER emulator was implemented in C using the information found in the CDC hardware manuals. There was one weird CYBER/6000 series console channel problem which we have been able to resolve using a similar approach. Paul Koning created a VHDL implementation of a CDC 6400 using hand written VHDL code for each cordwood module type and "wired" them together by processing the OCRed wire lists generating more VHDL code. He used GHDL to execute the VHDL and run some short test code which provided the definitive answer to the problem. The CDC manuals did not mention this specific corner case. Congratulations to Jay for this cool project. Best regards Tom Hunter On Mon, May 3, 2021 at 6:51 AM Chuck Guzis via cctalk <cctalk at classiccmp.org> wrote:
