I am still navigating my newly acquired HP49G+, and have more questions that seem deceptively simple but I really have no clue.
The full length user's guide (on the CD) indicates that the calc has a total of 2.5 MB, with, I believe, about 1 MB allocated to system use. There is supposed to be 1.5 MB of user-accesible memory as follows--240 KB Port 0 (IRAM), 255 KB Port 1 (ERAM), and up to 1085 KB Port 2 (Flash). This is what the memory allocation seems to be in the HP49G, at least from what I can see in my emulators.
But when I remove all objects I can find from memory and do a factory reset, the File Manager tells me I have about 240K Port 0 memory, 127K Port 1 Memory, and only 768K port 2 flash memory.
The back of the users manual that packs with the calculator indicates that the calc has 2.5 MB in total, with 512K RAM and the rest flash ROM.
So, my simple mind wonders, what happened to about 128KB of my RAM and 320 KB of my flash ROM? Apart from CASDIR, there is nuthin' left in this calc's memory, that I can find anyway....
According to VERSION, I have 1.23. The calc has not been upgraded to 2.xx.
I know that the HP49G+ is not well loved around this forum (purists don't even consider it a true HP), but, for the most part, I am finding it to be okay, I got it for a good price, and I am keen to demystify its quirks so as to maximize my enjoyment of it.
