In any case, I'm interested in hearing what you have to say on the subject.
Thank you for your interest.
Like everyone, I was waiting for someone to do something with the Commodore / Amiga intellectual property and we all know where that went. I can't exactly get old chips made so I decided to look at off the shelf parts that were available. There are a number of options that I could look at such as the Beaglebone Black, the Raspberry Pi, Uzebox, etc.
I chose the STM32 F4 Cortex ARM chip which is a 168 MHZ processor. The part I am talking about has development boards which I have but this is one of the parts without the touch screen:

This board can run several different LCDs including the iPhone LCD and Nokia LCD. I think I've even seen a Hackaday post where someone claimed this board could run a Radeon driver.
I thought that programming a chip that can run an LCD would be easier for me to start out on than trying to make a VGA ladder right from the start which would allow me to do other things but there are some video options.
I didn't make these videos but these videos show what it can do:

There are other GPUs that I could try to program with the board. There is enough i/o that I could add a keyboard, mouse, wii controller, etc. My goal would be a single board computer and I have all the hardware except for the ST Link which is inexpensive.
