I cannot remember the name of the 8086 trainer kit, unfortunately. That was more than 20 years ago. It indeed looked very much like the MCS-86 picture you have linked to. I could not have remembered the name of CPLD kit either if it weren't for the project report where I have kept a picture of the kit and its model name. It was Xilinx XC9572 PC84 CPLD Trainer.
i'd very much like something i can buy that would look like this: https://upload.wikimedia.org/wikipedia/en/3/3e/MYSTEM_86.JPG
there's just something about self-contained hardware that you can program from scratch that really appeals to me.
