This is a version of the CoreMark benchmark utility for the Tandy Color Computer. Please refer to the official CoreMark repository for more details about history and other patforms.

You'll need CMOC 0.1.84, lwtools, and ToolShed installed on your system. This was ported and built on macOS -- your mileage may vary on other hosted platforms.

To build the benchmark in a ready-to-go disk image, type:

make dsk

You can use DriveWire or some other method to bring the resulting disk image over to a real CoCo or use an emulator. CoreMark results are output to the screen.

• compile - compile the benchmark executable
• link - link the benchmark executable
• check - test MD5 of sources that may not be modified
• clean - clean temporary files
• dsk - create a disk image named COREMARK.DSK with the COREMARK.BIN binary suitable to LOADM under Disk Extended Color BASIC.

CoreMark is set to run the benchmark for 1 iteration. The minimum required run time for a valid result is 10 seconds. So far, a stock CoCo takes around 28 seconds, so 1 iteration is fine.
