    Apple III doesn't have any FPGA. Commented Jul 8, 2023 at 8:02

    There are other 6502 based computers like CBM Pet Series or BBC Micro. They too have an RF shield, a little place for the motherboard, a 2 MHz clock, and custom chips, but they don't have any heating issues. Commented Jul 8, 2023 at 8:16

    @wizofwor I don't know about the PET, but the BBC Micro had a fairly large, flat motherboard with a wide air space above it, and ventilation slots both underneath (a row of ports) and across the back; the only shielding was around the power supply. In fact, its cooling is the subject of this question — a comment notes that the processor ran fairly cool, and only the video ULA needed a heat-sink.

  • @gidds, so the source of the problem must be the power supply, or poor ventilation rather than the processor speed or custom chips. Commented Jul 10, 2023 at 6:40
