- I remember reading (and I'll hunt down the title if you'd like) that
- IBM's endedness came from a mechanical memory device that was something

- The consumate reference (IMO) is Danny Cohen's "On Holy Wars and a
- Plea for Peace", IEEE Computer v14n10, Oct. 1981, pp 48-54. I think

- published.

- to their standards of backwards compatibility. I don't recall them
- bringing in any linguists :)
