The biggest difficulty I had with a Spanish keypunch was getting the damned thing fixed. I'd gone over for a week to get a one day job done. The first three days were waiting to get what was apparently the only keypunch on the entire 10 acre site repaired. This was when I learned that
mañana doesn't mean tomorrow - it only means definitely not today.
Fortunately we already knew about the Spanish work ethic which is why I'd been allocated a week for a one day job. It was still a close run thing.
