The
IS-8400 Digital Planner series of Organizers were introduced already in the year 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 personalized lists |
| 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 TimeRunner 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 Memory Module |
| IS-8150 Link between the Organizer and an IBM-compatible PC |
| IS-8250 Leather Pouch |
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.
