The Philips MasterLab MC6400 was released in 1985 in Germany and was most likely designed in my birth city, Hamburg. It features a 4 MHz National Semiconductors INS8070 (aka SC/MP III) CPU. Claude code (Opus 4.8) designed the DAC - and wrote all the graphics demos and the space invaders clone as well. More info:
