Hi,

As an experiment I tried to put 604e@350MHz CPU onto Blizzard PPC.

Modification done:
1) PPC CPU replaced :wink:
2) Oscillator 60MHz with x5,5 which gives 330MHz frequency for CPU core
3) Removed original 2,5V voltage regulator
4) 1,9V/10A voltage regulator added ("classic" type soldered ad-hoc just to proof the concept)
5) +5V from power supply connected to 1,9V voltage regulator directly; without it I've measured 4,5V on the Blizzard PPC instead of 5V

As a results card is booting without RAM, but PPC is not recognized:

With RAM installed I have RAM error:

So I assume that Blizzard PPC software inside flash memory cannot init 604e correctly (lack of proper routines inside Blizzard PPC flash) and/or logic on the board is not working with 604e because onboard CPLD IC's are not adopted to serve 604e.

Anyway as I'm not a genius :wink: I will drop the idea to modify Blizzard PPC hardware/software and just un-solder 604e and put standard 603e@300MHz.

But at least I tried. :banghead:
 
maybe you can get compatible CPLD logic from a CyberStorm PPC ?
 
Despite the unsuccessful part of the test... That was a damn a fine job my friend!
It's nice you make such efforts to push as much as you can the BPPCs :)
I'm proud my BPPC has some work of yours done...

Keep up the good work and continue to inform us
 
The picture on the monitor looks nice!!
Are you using an Indvision AGA or an external scandoubler?
 
Thanks @mfilos my friend :)

In the near future I have a plan to upgrade Cyberstorm PPC; I have CPU's and voltage regulators already.

I'm using just standard RGB output from Amiga and SCART cable to connect my LCD VGA monitor with SCART input; there is no "magic" at all :D

@stachu

sorry to read of the bad luck, however nothing ventured nothing gained.

I do hope you get an opportunity with a cyberstorm ppc soon, if i had one i would let you have try at it!

alas only a csmk2 060

please continue your efforts, I am both awed and humbled by you work!
