Hi
I just bought a Newtion120 from ebay. I have a question. It comes with OS2.0. When I click on the 'i' in the Extras panel; it shows that 1130k of internal memory is used with 231k free. I was wondering how Newton handles memory. It originally had 840k free; I installed a few games and it went down to 231k. This worries me a little that I wont be albe to install much stuff.
Can someone explain how newton memory works?
Thanks

There are two types of memory on the Newton. One regular style memory that is used to run programs, etc. The other type of memory is FlashRAM. This memory is like a solid-state hard drive that stores apps, documents, preferences, and other stuff like that. If you want to see how much heap space you have free (program memory) in addition to storage space, check out Avi's Backdrop. It lists free heap space in the upper right corner.
For reference, I am looking at my 120/2.0 right now, and it looks like there is 1 MB of FlashRAM and somewhere around 50-60 KB of heap space (I might be wrong about the heap, though).

Oh, yeah, you can buy FlashRAM cards for the PC Card slot. Just make sure they are linear flash cards. Paul Guyot is working on a driver for ATA flash, but its not finished yet.

So if i understand this correctly, Flash Ram is like harddrive space on a desktop pc right. In that case, how can I increase the Heap space? Can I move apps from the newton to the Flash card to save heap space?
very confused

You cannot increase the DRAM of the MP120 AFAIK. The NewtonScript heap size (what you call heap space) is computed from the amount of DRAM. Fortunately, the Newton uses more of DRAM than the NewtonScript heap.
DRAM is used for programs to run. It's not directly linked with the amount of programs you can install.
Now, you can optimize the use the NewtonScript heap with utilities which will cache some data in it on the internal store (for example HeapMagic by GNUE).
