Newbrain Hardware Emulation

You can see here my progress on creating a Newbrain Hardware Emulation.

The ultimate goal is to make a Single Board Computer with a case to put it in.

Re: Newbrain Hardware Emulation

I have started development of the SBC (Single Board Computer) board i am just picking components to use for now based on the availability and cost.
Anyone willing to help please let me know.

The RS232 ic (16550) maybe will be removed if the implementation is done on the fpga.
