Texas Instruments PS-3600

The PS-3600 could be called "medium sized" Databank. It features more RAM than the simple Databanks PS-2100 and PS-2400 but far less capabilities than the Personal Organizers, e.g. the PS-6200.

Compared to the similar sized PS-2400 the PS-3600 added a third display row and expanded the memory from 2k Byte to 8k Byte RAM. The already known alarm clock got a weekly calendar and an adjustable world time.

The PS-3600 stores about 380 names and numbers in the memory.

Dismantling this PS-3600 manufactured in 1993 in Malaysia reveals a clean layout centered around a Toshiba TMP0201F-5105 Application Specific CPU with both integrated program memory and display drivers. Earlier PS-3600 were manufactured in Taiwan by Inventec Corporation.

We assume that this chip is very similar to the TMP0620F located in e.g. the Galaxy 67 programmable calculator! 

The data memory of the PS-3600 is rather small with just 8k Bytes capacity. The dismantled PS-3000 makes use of a Sharp LH5160 chip.

A similar housing was used even for a Translator, don't miss the PS-5800.

The later PS-3600+ combined the three line display of the PS-3600 with the design of the PS-2400+.

The PS-3600 is featured in the Texas Instruments Incorporated sales catalog CL-1233 dated 1994.
