How was the powerswitch fitted? It doesn't seem like it's a part of the PSU that you bought?


I bought the power switch from local electric shop. Just make sure that it isn't an push button that releases contact after pressing othervise it wont power up. To have the PSU powered up you need a constant connection between the wake up and ground after you break the connection ATX psu will power down.

After all this, you are parting with the magic parts???
With this wonderful mod, I'd think it would be time to BUY a BPPC and BVision for it and go OS 4


I still have a BPPC, but I decided to go with tower case and G-REX PCI which I haven't been able to get working... I just don't have the time and will power at the moment to streach my nerves with Amiga... I really hate the software problems and lack of good documentation or a simple tutorial from start to finish how to get your PPC working etc. I was in plans on doing one, but my plans has been pushed to distant future and might be that I will never try it as I still have my Peg II and seems like MOS 2.0 is hopefully around the corner.

Great mod! I feel the need to power up my soldering iron :flame:

I ordered one too. I'll let you guys know if all went well.

Great mod, inspires me to put a SAM in an A1200 case with PSU, 90degree PCI adapter and Keyrah.

Nice idea but how would you interface the A1200 keyboard?

A quick google later and I now know what a Keyrah is.

Thanks :)

Hello.

I've made the hack but I have one problem.
12v never stops to supply power!! (when the on jumper its out too)
5v works normal. On when its on and off when its off.

Any idea?

looking at the photo you do not need keyrah,you can still attach the standard A1200 keyboard.

one thing does concern me is heat under the floppy drive. pico PSU are silent PSU'S but here under testing i found the pico 120w needs cooling under *extreme loads* otherwise voltage will stray.

but this is a 200w PSU so under extreme loads keep a eye on temperture as this is under the floppy drive.

it's still a excellent project.

What jumer are you talking about?

Have you tired other 12V connections from the ATX PSU side, there are plenty of 12V outlets.

In my sterstest I found ou that it did not heat up much don´t remember exact readings but it was below 50 celsius. The PSU it self is quite efficient so most of the heat comes from the power brick attached to it.

im talking under **extreme** loads.

here is my deaktop config:

PICO 120W
A1200 desktop PPC 268Mhz with Bvision,128Mb ram,
indivision ( runs on seperate 3.3v from PSU )
elbox eide mkIII.

this is my cofig at the moment and the PICO 120W PSU is very hot on one side,i cant keep my finger there,so it must be around 50 to 60c.

this is with floppy drive,sound card and extra 128Mb of ram not attached.

all im saying is as you put more and more load on the PSU watch the temperture because it mounted under the floppy drive... in other words you don't want to be heating up the floppy disc if one is inserted.

Well PICO 120W shouldn't even be able to handle MAX currents that your system draws from 5VDC.
