HP-71b - Future "SD-RAM" Module - viable ?

[Garth Wilson]

I, too, have kept hoping someone would introduce such a product; but instructions should be compatible with the HP-IL file-access instructions that are already in the HP-IL module, and I think it would have to be an HP-IL device. This goes for the 41 also, even though a MicroSD card would fit in a top-port module which mechanically would be a neater solution (assuming you have a port available).

I am not aware of any bluetooth transceivers that can interface to lots of things at once like HP-IL can.
