A new release of the Incredible KIMplement, a Commodore KIM-1 emulator that runs on your Commodore 64. The KIM-1 is a 1976 single board computer with a 1MHz MOS 6502 CPU, 1K of RAM, six hex LEDs and a keypad, and was one of the first complete systems you could assemble for just a few hundred dollars. KIMplement uses a 6502-on-6502 virtualizer to run real KIM-1 programs on the C64, and while it can never run as fast as a real KIM (both systems are about 1MHz), it's still enough to run Tiny BASIC, FOCAL, Lunar Lander, even Hunt the Wumpus!
This new release not only improves execution speed by 10-15% using a form of instruction fusion, but also can give your virtual KIM a real serial port. Here's my Commodore 128D connected to my Raptor Talos II over the 128's user port at 300 baud.
