[Coco] Another Radio Shack Article

[Bill Loguidice]

I think historically we can look at backwards compatibility measures as not
really being a big help in the vast majority of cases. It's arguable that
the Apple IIGS, for instance, was as much hurt by being backwards
compatible with the Apple II, as it helped. Same thing for the Commodore
128 being backwards compatible with the Commodore 64. Why support a new
platform with few users, when you can just keep creating software for the
old platform (that still works on the new platform) with far more users.
