It's possible that the Nat Semi 65098 might refer to a wafer process
number and package code.
Wafer process #65 produced PNP devices for high-speed saturated
switching applications up to 50mA.Typical commercial type numbers are
2N5771 (TO92)
I've no info on a process 98.
The internal package code '98', however, specified a TO3 outline.
" " " " '65' specifies 14pin DIP ceramic.
