Hi there,
I recently purchased a 128K memory card at a reasonable price.
After installing it, I've managed to merge it with the 48GX internal ram, so I now have a lovely 256KB.
The intriguing thing about the card is that it DOESN'T use any kind of replacement battery. There is certainly no way to open the card, & no removable opening to insert a battery. It only has a write protect switch.
The card is made by: Microcards ?
Does anyone have an idea how this card functions power-wise?
Does it draw a tiny amount of juice from the calculator batteries to run it? - Even when the 48GX is OFF?
Does it contain a rechargeable 'battery' of some kind?
OR does it have some sort of persistent memory, that once written to remains resident until it is written to again, even if the card is removed? - OR if i were to remove the card, would anything stored on it would be lost?
It seems to be a professionally made card with a metal chassis.
Look forward to your insights.
