Information about an unknown IC

[jim stephens]

Could be speaking ahead of answers here, but TI had an entire internal 
PN system for their parts in the 70s (I dealt with it in 75) and they 
did it to stop people from doing component level repairs on such as TI 
silent 700s.  I don't think there's a common P/N part in those.

I couldn't get the internal to "real public" part number equivalency 
list and I was just a wet behind the ears EE trying to maintain 40 of 
them for a college, and quite pissed off that they did that. Some were 
figured out but most weren't.

They wanted upwards of the value of the units for parts, and were aholes 
in my book.  The Silent 700s weren't the only thing they pulled that on.

So if you have a schematic and what it came out of someone here or on a 
circuits or specialized list which deals with TI shenanigans might be 
able to guess what it is and what would replace it.

May not be this, someone may have a book with it in it, but I avoid TI 
at all costs for this reason. Enough problems with old electronics w/o 
dealing with crap like this.

thanks
Jim
