Commented on one of my shares for HSW Hook, and lammented that it wasn't compatible with the Multiboard standard, I decided to give it a go remixing that design, but it was easier to make it from scratch. So here it is.
Nice, seems like the original Multiboard spec is very well thought out. I do not have Multiboard stuff, but someone asked me to remix one of my HSW designs to fit Multiboard and here we are.
