There was enough flash and RAM available after finishing interpreter I decided to go ahead and impliment the ability to transfer programs to device using Serial. 

I suppose this takes away from the antiquated method of punching in bits manually, but for testing purposes it is great!

Using a py script with pyserial on PC side, and usb-uart adapter, it works! Kinda some buggy stuff had to sort through with transfering negative integers though. Will have to fiddle with it more to understand the serial protocol more.

I was also thinking about how I submitted this device to the Tiny Games Contest, but its not "exactly" a game unless you consider programming in an incredibly tedious way a game. It is definitively an educational device, and you could write some sort of game that runs on the device.

I suppose that will be my final hurrah before the contest ends, is write up some sort of game that runs on this device.

Toodleloo!
