| + | Mostly this is to enable other projects. It needs at least these features: | ||
| + | |||
| + | * reasonable amount of CPU and DRAM | ||
| + | * PCIe 3.0 x1 or better | ||
| + | * Internal ports: | ||
| + | - m.2 slot | ||
| + | - 40-pin with GPIO, I2C, etc... | ||
| + | - LP-DIMM | ||
| + | * External ports: | ||
| + | - HDMI | ||
| + | - gigabit Ethernet | ||
| + | - (2) USB 3.1 | ||
| + | |||
| + | 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. | ||

| Core concept is a piece of virtual tape that's infinitely long, infinitely wide, and has an infinite number of tape heads that can all be accessed remotely. A recording session is a server you log into, send recorded audio, receive mixed audio, and update a database of what should play when and with what settings. | Core concept is a piece of virtual tape that's infinitely long, infinitely wide, and has an infinite number of tape heads that can all be accessed remotely.

| + | 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. | ||
