It wouldn't take much to make a machine like that, remember for the most part the games were written for the limited graphics capabilities of the day. Some like the Commodore were for a rather different dialect of Basic and if assembled total babel as far as any processor today... I think... Does anyone yet USE 6502 assembler?.
there is though a thought that comes to mind... What about a product/proggie that could emulate those old boxes and the Atari's and...
Paul I owe you a deep apology for the comments about the two basics but the editor splash screen was just similar enough to trigger the memories and I guess something bad that I ate started this rant on my part and for that I apologize to anyone offended. Your Machine is impressive but I prefer the tether I have in the USB cable. Perversely I like the impossibility of accurate power to all Items. The lack of accurate power and especially ground force me to pay attention to detail as I use breadboards connected by jumpers to connect to my Mega. The other thing that I have no use for is it's prime feature because it is a networking type of device. All networks that use radio are essentially open and many that aren't are easily compromised. For my own security I prefer to use other means of data exchange. I do appreciate all the work that went into that really nice looking bit of engineering though. There are years of man hours to take the standards of the language and evolve them to what the language is today, I had a Sinclair ZX80 with the original integer basic and I bought the chip that expanded the language and included floating point math... But that was written for a Zilog ZX80?. The culmination of many efforts by a lot of people most of all you are very impressive, Especially the Networking thing as it makes it open to all machines with a shared network protocol. Strictly I see a prime issue in the price vs functionality, a cursory examination of the processor confirmed my estimate of I/O use as there are a large number of port pins unused. Another thought is that an Arduino is a multifaceted bicycle with training wheels in it's simplicity. It's simplicity is one of it's major features in that it forces a creativity that simply isn't there in the same direction as your board, Blow one up, buy another and hopefully... not do "That" again. There is the Creativity of making the "Crippled (was that the word?) device do some impressive and many things rather...
But I've advised people about some things I have had direct expierience with and there have been some nice projects... Too Perhaps the SolderCore price might be appropriate if made singly but although there is a lot of bang for the buck, theres also a great many bucks for something that uncomplicated even if you had chosen... but IMO it's still a niche compartment for the price and the method of use of that impressive chip... Better by Far as a Mega and compete with that end of the spectrum, ChipKit?, Maple?, The Due... on Oct 22 (Supposedly?) and as an aside or better a sop.. to make the software available for other similar structures, other Arm Cores, reasonably. Security would be no real issue if you retain a part of the software until the account is verified and charge for multiple activations with some kind of agreement or like the PDS 7.1 have it create executables for intel architecture or as a Java app. Again I apologize for my rudeness and for commandeering and likely boring some people stupid with my chatter. It did appeal to me however to put the Uno and family and this really nice board into the perspective I see them from.
