Now go outside and look at the sky.
I wrote about this recently when I found Matt West's cool Spectrum emulator on the web, and since then I've been looking around a bit to see what else is out there:
- Intel 4004 and MCS-4 micro computer
- virtual 6502
- jsMSX (Z80)
- Z80 Speccy
- 8080 Space Invaders Arcade
Since these applications are completely open and since there is no need for a development environment beyond a text editor and a browser, it has never been easier to take part in something as complex as emulation programming. I can't wait to see what all the new talent will come up with!
