Source: education.ti.com (verified 2026-07-13) · corroborated by amazon.com. The Texas Instruments official product page (education.ti.com) confirms this is the "TI-89 Titanium graphing calculator" and verbatim states its "Built-in Computer Algebra System (CAS)", "About 188 K bytes of user-available RAM", "About 2.7 MB of user-available Flash ROM", a "100 x 160 pixel display", and that it is "Powered by four AAA batteries" (user-replaceable cells → rechargeableBattery false). The Amazon listing corroborates the exact model (title "Texas Instruments TI-89 Titanium Graphing Calculator", Mfr Part Number 89T/TBL/1L1/D) and its structured specs: "188 KB RAM", "2.7 MB flash memory", "100 x 160 pixel display", "Screen Size 2.8 Inches", and "Display Type LCD" (buyer reviews confirm "NO BACKLIGHT" and no color, i.e. monochrome-lcd); the "three times the memory of the TI-89" note distinguishes it from the older non-Titanium TI-89. No USD MSRP appeared on either page — Amazon showed only a used price of EUR 59.54 under a Germany-geolocated session — so priceUsd is left null. examApproval, connectivity (only a generic "USB port" is stated, not the connector subtype), and weightGrams (only "10.24 ounces" item weight, not device grams) were not verbatim-sourceable and are null.
