Nothing else than the European design of the PS-2100.
The PS-2100 Databank features 4 useful functions:
|• The Telephone Directory stores names and telephone numbers
• The Scheduler stores appointments, meeting times and reminders
• A flexible clock with 12-hour AM/PM or 24-hour time showing day of week
• A calculator with 10-digits display capacity
The display of the PS-2100 consists of one line for alphanumeric characters and one line supporting only numbers. The PS-2400 packaged the same specifications in a conventional housing with a "qwerty" standard keyboard layout. The later PS-3010 combined the size of a credit card with a full keyboard.
The related IS-2100 PhoneBook combines the PS-2100 with a small booklet.
The featured PS-2100 Databank was manufactured in March 1993 by Nam Tai Electronics, Inc. in China.
The PS-2100 traces back to the TI-2100 Pocket Info introduced in the year 1987.
A blue edition of the PS-2100 was sold with the PS-9250 Data Bank Book while the PS-CARD probably never hit the shelves of the stores.
This is an interesting question - the Databank is only 0.2 inches (5 mm) thick!
|This picture gives you the last time the working PS-2100 Databank. The next step will destroy it!|
|Just after removal of the keyboard foil you'll notice the printed circuit board (PCB) of the PS-2100. The thin foil is one half of the switches, the PCB forms the other half. The later IS-8400 looks similar.|
|The backside of the PCB gives you just a small blob of epoxy resin on top of the single-chip computer. It seems to be the TMP0620F known from the PS-2400. Find another chip-on-board design here.|
