More about this type of keyboard...
No ThinkPad from the '90s had an integrated numeric keypad due to size limitations, thus a dedicated external option was a popular choice. IBM made several numeric keypads based on the same scissor-stabilised mechanisms used on later Model M6-1 keyboards largely produced by Alps for IBM.
