This is a demo of a Grundy Newbrain Home computer
Based on Zilog z80 @4Mhz, i am using an arduino uno connected to a SD Card and communicating with the Newbrain using the RS232 Serial port.
By using poke 19,9 i change the default storage device to RS232 so i could use load and save as usual.
You can see the real speed of the Newbrain as it paints graphics on the screen.
