I still have a few 84 pin PLCC XC95108 5V CPLDs Originally, I did a tape controller design with one before Xilinx discontinued them. I figured that using a discontinued part was not the way forward, so I dropped the project. Xilinx did/does have its ISE design suite, which is fairly easy to use. Eventually, it turned out that using a reasonably fast MCU with 5V tolerant I/O worked just as well and avoided the "mystery in a chip" of a CPLD. --Chuck
