75CX was one of the pre-release designations.
At one point, the plan was to have 8K and 16K units, which would have been the 75C and 75D. I'm not sure whether the 75CX was before or after that. But the 8K unit was dropped, and the 16K was introduced as the 75C. By mistake, a photo showing a 75D was in the press kit.
The 75D designation was used later, but had nothing to do with the RAM size.
