Just because! A home computer without microprocessor

Today, a circle closed at the Centre for Computing History in Cambridge, UK.

How? Well, one week before this project started here on Hackaday, I was at the Computer History Museum in Mountain View, US, and jokingly posted the following remark on Facebook:

That's an original Apple-1. The Apple-1 next to the Gigatron is a beautifully done replica. It's fully functional, complete with cassette interface. The PCB is drawn in the same way and the chips even have 1970s date codes on them. It's on display in an operational state. I could play around and type commands in the original Woz Mon to verify that the Gigatron version works the same.

Many thanks to David Williams for the great opportunity!

The grin is still on my face. The idea came up spontaneously when chatting with David, and it got better when I realised I had brought an EPROM with this Easter egg in it...
