The ti-8x and -9x calculators This is representative of the full line with the exception of the colour screen units, and the "n" units. what's inside... a heavy flashed board (telco rate for all be "e" series, they are nickel flashed and go peripheral) A green cpu board that falls into peripheral grade. A large support (not shown to save bs' bandwidth) that is al, al-ag, or al12 (al+mg) behind the screen. The large board in the 8x and 9x "n" series except the 80n+ are fully integrated and are cell class. The 80x and 90x t series all have a SOCKETED gold cap chip but even busted to hell fetch more on eBay for parts. In pieces expect over $15. Used working run $150+ T series are educational use only calcs that were purchased by professors/teachers as a kit wit 20-50 n units. A single t unit has a broad spectrum transmitter/receiver that should be sent to a jewelry refiner if dead. Has a large amount of rhodium and is outside of BS' purchase range. $50-$75 per board is common at today's rates for commodities pricing.
