heh, cute. I have a Spartan-3E Starter Kit dev board for which there is a bit file for Space Invaders. The board has a VGA connector, you have to turn the screen sideways (or your head) for it to look right.

I believe that there is at least one 6502 core on the OpenCores website, and I've heard of other people trying to write their own. It doesn't need a huge FPGA. The Starter Kit FPGA has 40 Kbytes of block RAM.

I also know of two FPGA (or similar silicon) projects that emulate(?) the
TRS-80 Color Computer (6809E & 6309)

FPGA arcade has a project of a complete C64 in a Spartan 3A. Amazing what we paid for this 30 years ago Smile

Even more amazing that this vintage technology is being emulated
by modern technology which outperforms it by several orders of magnitude,
and at a cost that is as significantly cheaper.


I'm glad to see vintage computing projects being kept alive though

hm, I think those people who use to work with these devices in their youth, have still so much code for it, that it is worth to keep the hardware somehow alive, since the real hardware mostly died already Smile

And once sticking to a device might maintain the love to it, no matter what comes. See all the Porsche friends in germany. A car having so much demand for repaiers with so much money for investment is not very reasonable to drive. There are thousands of enthousiasts though have a 1980tees Porsche in der their garage.

I remember BBC computers from school when I was 13 in 1988. We used to hack the games the school had on floppy disk ( really floppy.) Nutty was a great game as was Tutankhamen. I loved the computer room...I remember re-creating parts of Dvorjaks New world symphony on a score editor. Smile
