The IS-8400 Digital Planner series of Organizers were introduced already in 1993 and ahead the competition. With the slim housing measuring only 0.2 inch they fitted perfectly in a Time System including a calendar, Today pages and tabs for notes, meetings and finances.
The IS-8400 organizer keeps three main types of information:
|• Reminders with unlimited alarms
• Addresses with a capacity of roughly 3000 entries in three
• Notes sharing the same 64k Byte memory like the addresses
In addition to the basic Organizer function you'll discover:
|• A flexible clock with 12-hour AM/PM or 24-hour time
• Up to 4 daily alarms
• A calendar from January, 1960 to December, 2059.
• A calculator with 10-digits display capacity
• World time of 23 cities in all 24 time zones
• A backup battery
The display of the IS-8400 is very useful supporting 6 lines by 24 characters. The language of the menues could be choosen between five languages: French, English, German, Italian and Spanish.
The IS-8200 Digital Planner uses 32k Byte memory instead the 64k Bytes. In the United States a very similar product was sold as PS-9500.
The system could be personalized with some options:
|IS-8050 / PS-9000 Back-Up Memory Module|
|IS-8150 / PS-9020 Link Software for IBM AT-compatible PC|
| IS-8250 Leather
Most astonishing with the IS-8400 Digital Planner is the thin housing measuring only 0.2 inch. The technology behind the membrane keyboard is similar to the PS-2100 introduced one year earlier. The electronics of the IS-8400 uses a clever arrangement of standard components found already in the PS-6600 and continued with the PS-6700.
