That's a known production-quality Massbus emulation, based on a 486 PC with one custom card doing the Massbus interface... A card driven by a Xilinx FPGA which could possibly be 'read out'...? Crying shame time... Back in the mid 2000s I was in contact with John Jones... ex DEC hardware guru and the guy behind Setasi. I agreed to buy all the remaining bits of Setasi from him... Several units, doc, software - and his development PC with all source and design files. Then I had a bout with cancer, and by the time I picked up the threads again he had given up on me and chucked it all in the dumpster :( Mike
