Chip: TMC0981
Info:This Italian-made TI-30 (4376 RCI, November 1976) looks different from the original TI-30. Instead of the usually printed TI logo
and the TEXAS INSTRUMENTS nameplate, this one uses only a sticker, a metal plate with a black background and gold-colored writing, like other calculators made in Europe, TI-45, TI-57, Privileg SR-35NC, but also a calculator sold by Radio Shack in the United States, the Radio Shack EC-4000. Later, during production, the metal plate was replaced to adapt it to the US design. We are particularly fond of this one, as we have been looking for one for many years and finally found two in one week (2023).
Here's a nice display for the famous TI-30 LED. They could have inserted a small wafer into this PCB and then covered it with resin or soldered the integrated circuit, the TMC0981.

I have to thank Gaetano Perrella, former employee of Texas Instruments in Rieti for the donation!
Why were transparent shells made? Transparent shells helped visually where the CAD of the time was not enough, in this way further mechanical modifications could be made! (info Domenico Calì , former Texas Instruments employee).The transparent shells helped visually where the CAD of the time was not sufficient, in this way further mechanical modifications could be made! info Domenico Calì (ex Texas Instruments employee)
Another particular reason for the transparent case was to follow the behavior of the flexible PCB combined with the rubber keyboard, elements introduced for the first time at TI by us in Rieti. Info Gaetano Perrella (ex Texas Instruments employee)

Info: In the photo below, the test calculator used in the Rieti plant to test the TMC0981 chips. From an advertisement of the time! The most Famous. The TI-30 scientific calculator is more famous because it is the best-selling in the world (10 million units). In fact, no other calculator, at the same price, can give you the same performance at the same quality level. With the TI-30 you have the 8-digit display. The AOS (algebraic operating system) to set the expressions in the same sequence in which you write them, 15 levels of parentheses, memory, trigonometric functions, plus with the security of TI assistance even after a one year warranty!

Battery: ni-cd

Year: 1980
Chip: TMC0981
Info:The TI-30 was introduced mid of 1976 and found soon its way to the vision impaired people. The German company Schoenherr developed already in 1975 a refreshable Braille display and introduced in 1978 this Braillotron. Since 1994 the company Schoenherr GmbH refirmed as EHG Handy Tech Elektronik GmbH and introduced in 1985 with the Galixa Speech a scientific calculator with natural voice speech output and later the Galixa Braille a scientific calculator with speech output and a 10-cell braille display. This Schoenherr Braillotron was manufactured till 1985. Another approach to solve the communication with vison impaired people could be found in talking calculators like the TSI speech+ and the Orbit TI-34.

Chip: TMC1983
Info:At first glance is the European TI-45 identical to the SR-40. Surprisingly the TI-45 features a green vacuum fluorescent display (VFD), a major exception in the Majestic-line. Dismantling this TI-45 manufactured in September 1978 by Texas Instruments in their Rieti, Italy facility reveals a slightly more complex design than the SR-40 sporting a red LED display. Main reason is the higher operating voltage of the VF-Display, engineers at Texas Instruments are using a very effective way to generate -22 Volts out o the 9V battery with a simple voltage multiplier using just four diodes and four capacitors and an charge-pump oscillator integrated on the TMC1980 single-chip calculator circuit. Two variations of the TI-45 were reported, they differ in the mask over the display. View the later model with a molded TI-logo and TEXAS INSTRUMENTS nameplate.
On the side you can see the serial, the date of construction 53 week of 1977 and the nation of manufacture Italy.

Info: This rare TI-500 was introduced in the year 1974 and seems to be a sibling of the TI-450 and TI-620.The TI-500 is based on the TMS0200 Chipset for 12-digit desktop calculators but misses the usual 12-digit display.
Related calculators using this chip set are the SR-20 and SR-22. The first usage of the TMS0200 Building Blocks were the TI-4000 and the Canon 121F. The architecture found in this TI-500 differs greatly from these calculators, it uses the Data Chip TMS0203, ROM Chip TMC0305, adding the Printer Chip TMS0221 to control the drum printer.

TI-58 or TI-59 calculator this rare Marine Navigation version uses a specialized module with navigation related programs. The calculator was mounted in a expensive wooden box and equipped with a DC-converter for usage on a boat.
The TI-58 and TI-59 calculators introduced a novelty, the Solid State Software Modules™ with up to 5000 program steps. On the backside of the TI-58/59 you'll note a small lid with a place for a module. The Master Library, known as "Module -1-", with 25 different programs was included with the TI-58, TI-58C, and TI-59. Twelve additional Solid State Software Modules™, known as "Module -2- to -13-" were available from Texas Instruments as Standard Modules.

Card reader with replacement of the licorice wheel... As promised the photos. I used the 7 mm external and 3 mm internal tube, in some cases I had to use the 6 mm one (SR series), since you disassemble everything, clean all the gears and then use a lithium grease (little I recommend). Since you have to disassemble everything, clean the magnetic head with isopropyl alcohol.
