Yes my university textbook in Chinese (published in 1991) 
says INS8250. 

I am not an old timer but I still used Apple II in my
secondary school and PC XTs/ATs in the universities.
The AST 286 PCs were the best PCs in the department.
They have 1M RAM, 40M HDD and VGA screen and runs
DOS 3.3...

In 1997, I was studying in a lab where two 286 PCs were 
happily serving as email teminals (Pine for VAX OpenVMS). 
Later Microsoft Exchange came and it was replaced by
Pentium 133 PCs. Still the two 286 PCs were taken over
by another department which had one program which would
not run on any PCs faster than 25MHz. They were so 
happy at the time when they saw the 286...

And in year 2005, half of testing stations here is still
running DOS...

What is IMSA?

Xiaofan

This got me interested enough to drag out my Tech Ref copy,
  says: Aug 1981 first edition (would not have expected first 
edition in '81?) refers to INS8250...

so we all predate the PC, the AppleII, the IMSA....
ho hum...
