FS: Blizzard PPC 060@66MHz/PPC@330MHz with SCSI + 128MB RAM

[stachu100]

For sale Blizzard PPC upgraded by me:
1) MC68060RC50 rev6 working at 66MHz. Oscillator is socketed, so card can be downgraded to 60MHz to work with BVPPC.
2) PPC@330MHz
3) Onboard SCSI + SCSI cable suitable for tower system (see pictures)
4) New accumulator + new fan
5) 2x64 MB RAM; 128MB FAST RAM in total

Card is repaired: someone un-solder SCSI chip by un-professional way and some pads were off (see pictures) All pads were repaired by me, and now card is 100% working.

I will give 1 month DOA warranty under the condition that you have good AT (NOT ATX!!!) PSU and all electrolytic capacitors are replaced.

Due to the fact that SCSI cable is prepared for tower system, this setup is recommended, but card can work with desktop as well.

I will also add:
60MHz oscillator for BVPPC
User Manual (if I will find it, should be somewhere)
Copy of phase5 install floppy

For 10GBP extra (just to cover extra transport fees) I can add old SCSI CD-ROM and 9GB SCSI HDD, so you can have complete setup without thinking about termination/SCSI ID jumpers settings.
CD-ROM is reading genuine CD's without problems (see video), but CD-R and CD-R/W are not recognized. Please be aware.
Of course you can buy better CD-ROM later.
Any question please ask.

Offers via PM.

Several people reported problems with turbo cards (not only BPPC reworked by me) when powered from cheap noname ATX bought on ebay. The parameters written on them are just good wish and they are faaaar from true.

You do get decent ones for 25€ upwards tho (300W).

This is exactly what you should NOT do.
Anyway Blizzard is reserved already (outside amiga.org).

A PSU with a +5 v / 25 A is enough for a BlizzardPPC@330 + BVision ??

It's even too much. 5V/10A for desktop is fine. The most important is to have at least 4,85V on BVision. But why do you asking this? You know that as well as I do. ;-)

Issue solved : http://cosmosamiga.blogspot.com/2011/12/bvision-coquine.html

(Before, 4.48v !!)

See!!
No surprise that BVision was not working. ;-)
I have even better idea to be sure that BPPC+BVPPC will work stable. More info within 2-3weeks. Stay tuned! :-)

You know I coudn't run my Bvision but with an Amigakit PSU (more watts, shorter cable). With a 150wats one, giving 5.1volts in the PSU the Bvision coudn't boot I think that just caused by the lenght of the cable (original Amiga Psu lenght -too long-).
 
So I'm interested in your solution too.

Solution is very simple:
To add voltmeter!
I strongly believe in simplicity. :afro:
By doing so even two-left-handed person with zero skill in electronic can check if Amiga with BPPC (or with BPPC+BVPPC) will have enough power.

What is also very interesting that after simply mod this voltmeter can be permanently installed inside A1200 trapdoor so voltage can be checked by simply opening the trapdoor. Or this voltmeter can be installed inside modified A1200 case to observe voltage all the time.

In the video above you can see this idea working on BPPC, but on BVPPC it's very similar except that extra cable from PSU to FDD power connector is A MUST!
It's written in BVPPC instruction manual:
http://amiga.resource.cx/manual/BVisionPPC.pdf
But who is reading manuals nowadays? :biglaugh:


Procedure to be sure that +5V is ok in your system:
1) Install all necessary libraries for 060 on your system partition first.
2) Install BPPC.
3) Disconnect fan plug from BPPC.
4) Connect 5V voltmeter to BPPC fan connector. It can be connected in one way only.
5) Switch-on your Amiga.
6) Observe voltage readings on voltmeter. IT CANNOT TAKE LONGER THAN 30 SECONDS!!!!!! to avoid PPC CPU overheating.
7) Once measurement is done, switch-off your system.
Disconnect 5V voltmeter.
9) Connect fan plug to BPPC fan connector.
10) That's all!
:-)
Readings on the display should be above 4,85V to be sure that system will work stable.
Ideal case is to have 4,95V-5,05V.

If voltage is below 4,85V - your system might not be stable.
Please replace your PSU or please add two wires +5V and GND form PSU to power cable going to floppy drive.

Voltage can be measured on BVPPC directly by soldering extra connector for voltmeter on graphic card.

This voltage is a general propose 0-20V/0-200V voltmeter bought on ebay and adopted to work on +5V ONLY.

In the video above BPPC is working with extra +5V and GND line going form PSU to FDD connector and the voltage is 4,94V.
Once two extra lines form PSU to FDD connector is disconnected the readings are 4,76V.
200mV less!!!
So really extra wires from PSU to FDD floppy connector is great mod!
Of course assuming that PSU is good. :laughing:
