(48GX) SpeedUI 14.01 released:-)

[JDW]

Thank you for your detailed reply, Christoph!

Here is an exact quote from the EBAY seller regarding his FRAM cards for the 48GX:

FRAM cards are much faster then older SRAM cards, but the gating factor is
not performance of the card, but performance of HP48GX reads and writes.
FRAM card maxes out performance capabilities of HP48GX, so in real terms it
will only be slightly faster then older SRAMs. My guess is about 20-30%
improvement

So he says "older SRAM" cards, which per your reply today would put them in the 70ns or 100ns category. And since those HP branded "older" cards are still sold on EBAY even to this day, it perhaps is a reasonable thing for him to have told me. But you are right, if comparing a "modern" SRAM card to an FRAM card, the speed difference should be negligible.

But since the 48GX was built back in the mid-1990s, system RAM on the calc's PCB would be old tech RAM. So wouldn't that mean that a modern tech SRAM card or an FRAM card would be at least as fast or faster than that buit-in 128k of System RAM? Or is even merged memory on a card in Slot 1 slowed down to be slower than system RAM, regardless of how fast that card may be?

Thanks.
