Appendix A: PoGa File System Overview

The PoGa File System is a

Fixed Block Architecture

(

FBA

) in which each addressable record on disk is of the

same size requiring no 'disk operating system'. It was designed to be as simple as possible, and the

position of all files is determined simply by offset.

Each 'file' consists of 4096 sectors (2097152 bytes or 2 megabytes) . There are 512 'files' consuming a little

over 1gb of storage, therefore the minimum media storage capacity is 2gb. The remainder of the disk above
the PoGa files is classed as a

Common Storage Area (CSA)

and is available for general purpose usage.
