(similar to today's badge, gumstick and single-board form-factor prototype systems).

The MARCH collection represents the diversity of CPU manufacturers and architectures that were vying for the market before the IBM PC dominated the scene, forcing everyone into being IBM-compatible (now merely x86 compatible). Well, except for Apple. And mainframes. And embedded systems …
