PS-3600_BACK.jpg (314457 Byte)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.

PS-3600_PCB.jpg (449812 Byte)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.

PS-3600_CPU.jpg (141681 Byte)We assume that this chip is very similiar to the TMP0620F located in e.g. the Galaxy 67 programmable calculator! 

PS-3600_RAM.jpg (67706 Byte)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.
