HP-48 FRAM Cards

[JDW]

gege mentioned that his 48GX was upgraded internally, adding 128k to the existing 128k. How does that affect usage of cards in Slot 1? Is Slot 1 still restricted to 128k? And can a 128k card in Slot 1 still be merged with System RAM, yielding 256k + 128k = 384k?

Next, even if a wireless interface were added to this concept FRAM card, wouldn't the data throughput be roughly the same as what we get via cable anyway? If so, it makes little sense to invest the time, energy and expense to include it. The convenience benefit would be marginal at best. It would be more of a neato feature than anything else.

As to FRAM chip tech, I would agree that any new card design should use the latest chips, even if they are marginally more expensive.
