Help needed to build a very small adapter (BlizzardPPC)

[Cosmos Amiga]

Hi everyone !


The ppc.library (PowerUP) into the BlizzardPPC firmware fail with zero fastram available
when 1 Mb Kickstart plugged in the rom sockets.

So, we need to remove this ppc.library from the firmware and put it if needed into
Sys:Libs/ on the harddrive...

I have disassembled the last firmware v44.71 and removing this library is simple now...

But, the original TSOP eeprom 29F040 have too tiny pins, and soldering/desoldering is
a bit risky you know... I want to keep safe my beloved BlizzardPPC...

So, I need a very simple adapter, only tracks and zero components...

It's a 45 minutes job under Eagle (I need a .brd file for http://www.oshpark.com)


Anybody wanna build this adapter ?



Thanks in advance !

Some progress :


ppc.library v46.35 removed

New checksum calculated for a new firmware v44.72 ready to go...

Cannot wait to have a try...

Even with hot air, soldering is risky : tiny pads can go away with the heat...

The ppc.library was compacted : I depacked it and it's the v46.35...

The last ppc.library released for the CyberStormPPC was the 46.31...


Of course, for fixing this adapter on the BlizzardPPC, I'll use "scotch" in french : http://www.castorama.fr/store/Adhesif-double-face-special-miroirs-22-mm-PRDm123100.html

Without the ppc.library, I have now about 332 Kb free into this new v44.72 firmware...
