Conceptually, throwing a bunch of ICs, glue-logic, and some RAM etc. on a PCB is dead easy. The stumbling block here is the PC compatible BIOS. Is there an open source BIOS available that supports all the standard PC BIOS calls ?

- pjc50 6y agoThe result of the project on that blog will be something that looks very, very different from the PC compatible! The only thing it will share is the "personal computer" name. You probably could build an ISA bus IBM compatible PC out of microcontrollers, and port one of the open source BIOSes to it, but the utility of such a thing is questionable.

- jamesmunns 6y agoHey, author here! I definitely think the communication protocol is the special sauce here :). I am to focus on this in a couple different ways, largely based on either a pub/sub style format for smaller periodic messages, or on a mailbox style format for larger messages (display frames, etc). I'm still pretty early in the brainstorming process, and this is intended as a hobby/teaching project, but I'd love to have things be useful for everyone using it, and having compatibility APIs are a big way of achieving that.
