Thanks for all the links. I already did some ATX conversion without the soft power mod. My first attempt with this mod (soft power) was a fail. I use seasonic PSU as they have enough power ans small form factor to fit in a IIcx PSU.
The IIsi PSU looked fine (and it's a SONY PSU) so I decided to...
Ok, I understand now how it works in detail compared to ATX PSU. It's "just" a simple link from pin 10 to 9 (with resistor ?), to power this PSU.
Unfortunatly, when checking, I link pin 10 & 9 with a 1 k resistor and something blew inside the PSU (not instantly, but after some times). Those PSU...
Thanks, when plugged, my PSU shows only 5V on pin 10, which seems correct as this pin is the 5V stby line. What does the motherboard do with this 5V to tell the PSU to start ? (applying this voltage elsewhere, shorting, .... ) I can put a dummy load on the 5 and 12 volts lines if necessary, but...
Hi everyone, I want to buy some beigeATX to replace my dying PSU (IIci, IIcx, IIsi, ...) but can't buy directly from Anserine as their shop cannot deal (yet !) with EU countries. Is there anyone from this forum that can buy some for me (like 5) and then ship them here in EU (Belgium) ? Of...
Hi everyone, I just recapped the MB and PSU from a IIsi. With the PSU out of the computer, I have a nice 4,96V from the 5V stand by line. How can I start the PSU without putting it in the computer. Which pin of the 10 pin connectors tells the PSU to start ? I want to do this before putting the...
My additional PSU is not working. Do you know what voltage is it supposed to provide ? I guess there are 2 different voltage, one is 12V for the fan, but the other ... ?
Hi,
It looks like we have the same board. I finally took the time to disassemble everything.
Here are the pictures.
This is the extra PSU, the power is taking directly from the main AC so it doesn't stress the analog board.
At the back of the computer, we found this extra card, there...
Hi,
I had for a long time in my attic an Apple II inside a wooden box. I don't know what's was the story of this computer. The box is paint and looks nicely made.
They are several card inside. I can identify the Disk// interface, an Z80 card, also a 80 column card ?, an another card without...
Hi, I checked the original charger (I have two of them). The one I'm using is giving me 7,4V - I assume is correct.
It's a replacement battery that looks in shape. Can a bad battery cause those errors code ?
Thanks,
