My #RC2014 Orton 3C computer is up and running.
This is a really low level Z80 computer that you program in binary using the switches on the right side of the panel.
In this example I’m callling some code in ROM to rotate the value on the left hand switches and display it on the LEDs.

This is the code I toggled in. It just calls some example code in ROM. 0000 0000 00 NOP 1100 0011 C3 JP $4150 0101 0000 50 0100 0001 41

@robertprice@mastodonapp.uk Not sure if the 😍 emoji quite does that justice!
