Caution!!!

To be able to do the work described below it is required that you are used to solder SMD Parts and own the propper equipment.
If you haven't, contact a person that is capable.
Remember that you risk a severe damage of your card and/or your computer. I dont give any guarantee or responsibility that the modifications showed here do work and are correct.


List of parts

(required for both upgrades)

1* Motorola 68060 CPU mit 50MHz
1* 50MHz Quarz Oscillator (about 2EUR)
1* 3.3V 5A Voltage regulator(LT1085CM3.3) (about 7,5EUR)
3* BY77 SMD-Diode (or even 1N4001) (about 1,5EUR)
1* 16pin precision socket pol.(about 0,3EUR)
1* 3pin jumper connector with 2pin Jumper (about 0,2EUR)


Rework Phase5/DCE Cyberstorm MK2 from 040 to 060 Version

P5CSMK2 As the PCB of the 040 and 060 Version of Phase 5's (DCE) Cyberstorm MK-2 are identical the upgrade is not that hard to do. Remember to install the required 68060 libraries before you remove the working card. As the first step you should carefully remove the old CPU. Now desolder the power-select jumper (JP2) inbetween the CPU and the voltage regulator (IC2) at the bottom of the card and the old 80MHz Oscillator (Q2). You only have to added the Voltage Regulator (IC2), which is seated in the middle of the CPU and the lowest SIMM-Socket, the SMD Diodes (D4-D6) above the regulator (IC2) with their line marked end towards the CPU. Insert the socket (with the unneeded pins removed) at the oscillator's place (Q2) and the jumper connector (JP2) where the power source was. Now you have to reseat two resistors (R3, R4). The first one (R3) is placed on the far rigth handside inbetween the top and the second SIMM-socket. It has to connect the middle and bottom solder pad instead of the top and middle one. The second one (R4) is inbetween the left clamp of the two middle SIMM-sockets. It has to be moved from the left to middle solder pads to the middle and right ones in the lower row. After that, you can insert the oscillator (Q2) , the Jumper (JP2) (connecting the two lower pins) for the 3.3V power supply of the 68060 CPU and the CPU itselv. Its currently not clear if the PAL should or must be exchanged. If you did all steps propperly and carefully, everything should work fine now.


Rework Phase5/DCE Blizzard 2040 to 2060

P5B2060 As the PCB of Phase 5's (now DCE) Blizzard 2040 and 2060 are the same someone like me would like to upgrade it himself. Remember to install the required 68060 libraries before you remove the working card. Of coures one would have to exchange the CPU (040 to 060) and the oscillator (Q1) (from 80MHz to 50MHz) at the top left corner. But you also have to add a voltage regulator (IC1) (LT1085CM3.3) - at the left corner of the card at the height of the bottom CPU corner - to provide the 3.3V needed by the 060 and 3 SMD diodes (D1-D3) (BY77, or even 1N4001) inbetween the regulator (IC1) and the CPU with their marks facing down to prevent damaging the CPU on power on. Those must be activated by changing the power source jumper (JP1) next to the middle diode (D2) and left of the CPU. It must connect the two lower pins for supplying the 3.3 Volts. In the middle of the CPU socket there is a solderpad matrix with an resistor (R2) at its right side. That 0 Ohm resistor must be replaced to connect the middle pad with the opposite one (from top-middle to middle-bottom). Do also desolder the resistor (R1) seated left to the two resistor arrays and right to the PAL. So far no reason is known for which the PAL (which has a different color marking) should or must be exchanged. If you did all steps propperly and carefully, everything should work fine now.


Rework Phase5/DCE Blizzard (PPC) 1240 to 1260 (PPC)

As the same PCBs were used for the different CPU versions of the card, the rework is possible here as well. But the bad thing is that in most cases no CPU sockets were used due to the limited space. For this reason the rework should only be done by a skilled company. But even there is a high risk of damaging the old 040 during removal process. Make sure that the PCB does'nt get damaged at all. Even if you got a socketed version, it may be that you have to solder in an additional row of contacts to the inner ring.
