@Moors7 I agree, I like the current models as well. But for some applications it might come in handy to have a full system, for others only a part of it. So the current systems are OK, but there eis just a gap to fill some applications (if you have these kind of interfaces, to existing systems you need all communications and in the case of a 1 CPU system you have it all instead of interconnecting them).
But I agree the current set is good
