Description
The mbm file type is associated with the Psion Series 5, a range of personal digital assistants (PDAs) developed in the mid-1990s. MBM files are specifically used to store bitmap images on these devices. These images could be used for various purposes, including as part of applications, for the device's interface, or for user content such as photos or graphics. The format is tailored for the limited processing and display capabilities of PDAs from that era.
