Texas Instruments introduced a very powerful Translator in a housing similar to the PS-3600 Databank.
Due to limitations of the internal memory two different models were available:
• Version 1: French, English, German
• Version 2: French, English, Italian
The internal memory stores about 10,000 words, 420 business words and 920 complete sentences in 13 different categories. By simply choosing a word or sentence in one of the three languages the other two languages could be displayed.
Dismantling this PS-5800 Translator (Version 2) manufactured in September 1993 by Inventec Corporation in Taiwan reveals a single printed circuit board (PCB) sporting a very clean design based on just 4 integrated circuits (ICs):
TMP0230H-5113: Application Specific CPU
• IEC50387A-01S1 and IEC50387A-01S2: 256 kByte ROM
• Toshiba T6A21: Single-chip 66 segments display driver
The picture on the right gives an enlarged view of the Toshiba
TMP0230H-5513 Application Specific CPU. The identifier -5513 seems to indicate
the Software Version of the integrated ROM.
This PS-5800 makes use of 2 Mask-ROMs labeled IEC50387A-01S1 and IEC50387A-01S2.
The picture on the right gives a close-up view of the Toshiba T6A21 single chip display driver, supporting a maximum number of 66 segments. The layout of the PCB shows a joint effort of the TMP0230H and T6A21 to manage the 95 columns and 14 rows of the alphanumeric LC Display plus the various indicators.
The Translator traces back to the PS-5600 and the smaller sibling PS-5400.
