Texas Instruments introduced early in the year 1996 a new series of Personal Organizers. It could be traced back to the PS-6200, the first Organizer with the Texas Instruments label.

This PS-6700 looks identical to the PS-6800 with more storage capacity. Like most other PS-6xxx products these two products are compatible with the PS-6155 Dock-station cradle. The PS-6155 connects the Organizer with a IBM-compatible PC and synchronises the Organizer with Lotus Organizer 97 software. 

The PS-6700 organizer keeps three main types of information: Reminders, Addresses and Notes. Within these three areas, there are many different ways to store and recall information. The huge memory of the PS-6700 with 64k Bytes size is flexible and could be divided without any limitations among the three files. In addition to the basic Organizer function you'll discover:

A flexible clock with 12-hour AM/PM or 24-hour time
A calendar from January, 1960 to December, 2059.
A calculator with 10-digits display capacity and 12-digits of accuracy
World time of 62 cities in all 24 time zones supporting one home city and 4 world cities
A backup battery

PS-6700_1.jpg (20479 Byte)The display of the PS-6700 is very useful supporting 6 lines by 24 characters with crystal clear letters. 
The PS-6700 was replaced soon with the PS-6760Si and within another year with the PocketMate 200. Models with much more memory were available with the PS-6860Si / PocketMate 300 (128k Byte RAM) and PS-6960Si / PocketMate 400 (256k Byte RAM).

The hardware of the PS-6700 is similar to a lot of other products: A 8-bit microprocessor of the Z80 family, a huge ROM of 64k Byte capacity, a RAM of 64k Byte size and a driver for the LCD display. You'll find similar architectures with just another balance of RAM and ROM capacity:

Product ROM-size RAM-size Example
Spell-Checker 128k Byte 2k Byte RR-1
Data Bank 64k Byte 64k Byte PS-6700
Graphing calculator 128k Byte 8k Byte TI-81
Modern graphing calc 512k Byte 32k Byte TI-83 Plus

The pictured PS-6700 is serial number 0000047 and uses an alterable EPROM for the main software instead the later Read-Only-Memory !
