| + | The card presents itself to its host as one or more devices. It can pass through its USB host adapter, network adapter, and m.2 slot, and act as a GPU. It supports SR-IOV. You can boot off it. With the right hardware support, it should be able to stay awake while the host powers off or reboots. | ||

| + | The 6502 can't drive the C64's memory anywhere near full-speed, but the ROM port has a DMA pin, so a DMA-capable cartridge can do impossibly cool things. I'd like to find a good demo playback engine that already exists, and adapt it to play back data being streamed in over a network. | ||
