Although the actual motion and resistance has not changed, some older arc trainers (600Arc, 610Arc, 630Arc etc.) had an incline range of 0-10, where 750Arc products and later (625Arc, 770Arc, 771Arc etc.) have an incline of 0-20 range.
A user would be able reach the same type of incline on an older model by essentially doubling the incline level.
