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

[KeithB]

I keep trying to decide whether it would be better to write code to get the 71 to access the card directly, or get a small MCU to translate between the 71 and the card using FatFS:

I lean towards the latter.

But it would have to get in line behind all my other half baked projects.
