Hoppi 1.3.2 Release

[JDW]

Han,

Thank you for your tips. But I've been speaking with Oleg, creator of the 128k FRAM card, and we finally found a solution. Last night, I swapped C1 & C3 with 47uF SMD polarized caps, but in that condition, when I press ON with the FRAM card installed, the pixels on the screen look like they are exploding and then the screen goes blank and nothing happens. That remained true even after I restored C3 back to 4.7uF (while keeping C1 47uF). It could be that polarized caps won't work on memory cards, or maybe the calc simply could not supply the required inrush current for the 47uF cap.

Today, Oleg wrote me back saying he had found a solution. He used 10uF caps, but since I don't have that size on a non-polarized ceramic SMD cap, I stuck with the 4.7uF caps. But he told me to remove R3 entirely and then swap R4 for a 2kΩ resistor. I used a 1.8kΩ resistor, since that is close enough.

Here's a scan after the PCB changes:

The end result was that despite sticking with the stock I/O transfer settings (ASCII, etc.), all 2140 packets (131077 bytes) of MKRAM.KER finally transferred to my 48GX!

Yippee!

I of course transferred the "RECV.KER" (10 packets) first. After they both downloaded to the 48GX, I then typed 'MKRAM.KER' and pressed ENTER, then pressed the "RECV." softkey to install. About 10 seconds later it beeped and showed Meta Kernel Ver. 2.29 is installed!

When I press Right-Shift and VAR (MEMORY), I see META-KERNEL'S FILER and Port 0 with 121084 bytes free.

So it seems it was the FRAM card after all. Thankfully though, we got it fixed (it would seem). Now I can finally play with Meta Kernel! Probably after about a month of use I will compare with Speed UI to see if there are any benefits. But honestly, the main reason I was drawn to Meta Kernel was the fact that the Equation Writer is built-in, but Speed UI requires a third party EW that I've read has some bugs.

Anyway, thanks to one and all who helped.

Paul, I don't know if I should continued to use the special version of Hoppi you made for me, but it was that version I used to transfer Meta Kernel today!
