71b memory question Message #1 Posted by andy on 7 Feb 2003, 11:32 a.m. I've seen memory modules for the 71b which plug into the card-reader port. Do these modules act as RAM or do they just act like electronic disks?

However, they can be configured as non-volatile RAM disk depending on your requirements. **vp

And they are battery backed up. Message #3 Posted by Mike on 7 Feb 2003, 1:58 p.m., in response to message #1 by andy Most of these card reader RAM modules come with a battery so you can remove them and reinstall them later and not lose any data.

I've got one, it looks terrific and works extremely well, you can dimension and work with a complex matrix up to 95x95, which is ideal for large circuit analysis, or a 135x135 real matrix, for curve fitting and forecasting.
