The
PocketMate series covers the models 100,120 and
140 sporting a small display and
the models 200, 300 and 400 with a very useful display
supporting 6 lines by 24 characters of crystal clear letters.
The PocketMate 200, PocketMate 300 and PocketMate 400 replaced within one year the similar PS-6760Si, PS-6860Si and PS-6960Si. The main differences are the enhanced keyboard layout with larger keys compared to the earlier models. The evolution of the Organizers could easily be explained.
 | PS-6700: Small keys, optional PS-6155 Dock-station cradle |
| PS-6760Si: Still small keys, added S (synchronise) and i (Indiglo). Synchronise links to the Lotus Organizer 97 software and Indiglo is the greenish night-light with an extra button. |
| PocketMate 300: Larger keys, and still the Si options. |
The progress in the memory capacity allowed much higher storage capacity compared to early Personal Organizers. The PocketMate series uses 128k Byte memories, the layout of the printed circuit board (PCB) accomodates 2 chips.
The PocketMate 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 PocketMate 300 with 128k 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 |
The PocketMate series was together with the Avigo 10 the last organizer in a
long line started with the PS-6200 and the simpler Mini Data
Bank. About one
year after the Organizer series was discontinued the TI-83
SE graphing calculator appeared with an integrated organizer function !
