CGACompatibilityTester

The CGA Compatibility Tester, as its name implies, is a program that benchmarks and stresses nearly every capability of the IBM Color Graphics Adapter (CGA). This can be used to:

  • Verify that your clone CGA card is 100% compatible with the real IBM CGA
  • Similarly, verify how badly your non-CGA card (or software emulator) screws up CGA emulation
  • Benchmark adapter RAM speed, to compare with other adapters
  • Calibrate your CGA RGB monitor for maximum enjoyment
  • Calibrate your video capture equipment for the best possible video capture
  • Satisfy your curiosity about how CGA can be tweaked

Full documentation is included in CGA_COMP.TXT.
