A PC has a BIOS. You need the BIOS to install an OS. A PC won't boot without a BIOS but will boot without an OS. People have gotten Windows 1.0 running on an NES. Some older consoles like that didn't use a custom CPU but an off-the-shelf one, made in the 1970s like the SEGA Genesis. Those CPUs were good for a long time. The Motorola 68000 was used in multiple consoles and computers from SEGA, Atari, Amiga, and computing devices in the 80s, and 90s. |
Modern consoles all run an OS anyways. PS5 has a BSD based system, BSD being a classical Unix system. Xbox runs a modified Windows called Xbox systems software. Nintendo has developed their own microkernel for the Switch operating system. So according to his definition modern consoles all are PCs anyways, while old computers like C64 or ZX Spectrum that did not have an OS aren't.
