Serial input to 8bit parallel output. The data is stored into a shift register then it is copied into an 8bit buffer. Two digit displays show the content of the buffer. On top left side you can find the switch for the serial input.
Unfortunately the simulation is very slow and hard to debug, but it seems to be working.
(At the bottom there are a few inverters used to delay the reset of the counter, this is needed in order to have enough time to fill in the buffer)
