1. Bus logic:
   Basic logic gates(AND,OR,XOR) that operate on busses rather than single signals.
   This would be very useful where compactnes is important
2. Register:
   This one has a bundled i/o, and two single signals: read and write.
   when write is on, the contents of the bundled io are stored inside the gate.
   when read is on, the contents of the gate are put onto the bus.
   This is useful in building computers and such

You can create these yourself now with Fabrication.

I totally approve the XOR bundled gate, which could be very useful with multiple inputs in a system. Other gates could be useful too.
Concerning the "register", it's like a RS-latch for bundled signal ?

rather a D-latch(or transparent latch)

And yes, 2x Bus input panel + Bundled XOR = Epic

I consideeed such a thing quite a few times, but then I think that if something that complex is needed, might as well use computercraft logic or something... Not a yes but not a no.

The register is interesting though. Maybe something like a 16 bit bus register with parallel load.

You might be able to get your bundled idea using MightyPirates/OpenComputers#711 new microcontroller

yes, i love that one, might try doing a 16k ram in a single block space!
