Re: [50g] Cards, connections, software and how?

2GB is the limit for FAT16, implemented on HP50G, and we dont need more, I using a old 16MB SD Card with all my HPGCC tests ....

Everywhere you look online to buy a 50g, a pitch for a 2GB  SD card can't be far behind.
Is that address limit (2GB) in the OS, or is it strictly machine driven, because of the format involved at the time the tech was on the drawing boards?

I find myself wondering if there isn't some way to get around this by adapting the hardware to accept a USB drive One of the tiny ones, smaller than a USB connector itself. If there is some way to mess with this limit, and not bash the baby with a brick, I find myself wanting to extend this Idea, so that a larger capacity drive could be carved off in slices, and what you would have in the end would be a stack of "SD cards" on a mini thumb drive.

But as much as I know how to use the machine itself, I must profess a certain lack of knowledge about what and where the hardware/firmware boundaries are, and what those "hard coded" limits might be. I know that you can fiddle with the CPU speed a bit, and I know a few more tricks of the trade, just from being familliar with how far and how hard I've pushed the hardware and the software myself.

The reason that all this got started is that I now carry a very thick case of cards, which more resembles a wallet than my wallet itself. A week or so ago I found myself at a Research library, and found that I'd lost the case on the train, or left it at home. (I left it at home, and picked up my old wallet instead) Being a grizzled veteran who goes alll the way back to C/PM, I had back ups of all my programs with me--on the flash drive that I carry constantly, and no way to bridge the gap, since I don't carry a laptop/netbook/ implanted machine (It won't be as long as you think, stop snickering!)

Anyhow, I'm asking this for another reason. The day will come when 2 GB SD cards are as rare as the old plug in memory cards for the 48GX (that day may not be far off either) and I'd like to look to "workarounds" for what might become a memory shortage (my own or the calculator's) sooner than I (or anyone else) might be comfortable with.

Any thoughts?
