Just a minor variation of the 1989-model of the TI-30 STAT. Please focus on the texture of the housing if you compare the designs.
In 10 years of production we recognized in the meantime seven different designs of the TI-30 STAT and - just to compare - four designs of the related TI-30:

this late TI-30 STAT reveals an interesting internal construction with a
flexible printed circuit board (Flex-PCB) instead of the common rigid PCB's of
other calculators manufactured in the 90s. We
know this type of design from e.g. the TI-30 III
manufactured in 1985.
The single-chip calculator circuit located in this late TI-30 STAT looks uncommon but sports a well known designator: CD4557A - a member of the TP0456 architecture, based on the famous TMS1000 Microcomputer family.
Don't miss a BA-35 Business Analyst
manufactured in 1996 sporting a CD4571B, probably the latest TP0456
In 1993 this successful calculator was discontinued. Texas Instruments introduced a complete new family in a smoother housing:
TI-30X New display with 10 + 2 digits, 3 memories
• TI-30X SOLAR With Anylite solar-cells
• TI-35X Adds 2-dim statistics and hex-calculations
• TI-36X SOLAR With Anylite solar-cells
