The original Pagewriters (the grey models) had limited memory for applications. 
One of the early drawbacks to the unit was that at the time of development the flash 
technology just was not there to be able to read and write to a single flash at the 
same time. So the OS and apps sit in one flash and memory an others in another. 
Also 512Kx16 sram on board. The transmit antenna sits behind the LCD display in 
the flip. 

There was a neat hurricane tracking program written for the Pagewriter 2000 
models. Every time the NHS updated the coordinates you got a page and the 
information was displayed on a map. The program also tried to do a short range 
projection of where the storm was heading. Yes the map used vertical and the 
horizontal scrolling to get a VGA map onto a 1/4 VGA screen. Timeport models are 
nothing more than a Pagewriter 2000 with different color housing. It was an attempt 
to align the product with more popular celluar products as gain brand reconginition.
