The production of the TI-1100 II was shifted about 1987 from Taiwan to Malaysia. Both calculators look identical, nevertheless got the inside electronics major changes.
Recnetly we spotted a TI-1100 II
manufactured in Taiwan late in 1989.
In 1991 the design was changed dramatically and we got the TI-1100+.
Please read this anecdote from Gary N. Schumann:
"I bought one when it first came out and used it to
calculate my tip percentages and to do my check out when was a waiter working my
way through college at the University of Texas in the mid-1980s. Later, after
eventually graduating law school - I pulled it out of a drawer - and to this day
I still use it regularly to calculate my billable hours, post-judgment interest,
I throw it in my brief case and take it with me to mediations. The funny thing is - in all of these years, I have never replaced the battery. It is still operating on the original battery that came with it when it was bought all of those years ago.
This has certainly been one of the most reliable pieces of electronic technology that I have ever purchased."
