Thanks for the help and assistance in this matter. I've just swapped in a spare power supply producing 4.9v and the problem has gone. The recap will have to wait :-)

Yes it's been recapped. But I've just checked the voltages at the port and the 12V is reading 12.72v and the 5v is fluctuating between 4.59 and 4.62v :-(

My SE/30 has now started rebooting by itself in a vicious loop, and "extensions off" makes no difference. On a couple of switch on's it also displayed the shown pattern for a couple of seconds, which then disappears before it tries to boot?

Thanks for that, but thankfully replacing the resistor at R55 solved my intermittent "no bong and black screen" issues :-)

That too! but I have lost a lot of sleep lately.

Doh!,  The spec for component Q10 on the International Mac Plus analogue board was in Addenda D of The  Macintosh Upgrade & Repair Secrets all the time, I just had to find it by using the lesser known skill of "reading"  :blink:

It seems that The Dead Mac Scrolls doesn't refer to the Plus specifically, and doesn't say much about INTERNATIONAL boards. The  Macintosh Upgrade & Repair Secrets, also written by Larry Pina, does mention INTERNATIONAL boards in Chapter 6 "Dead Sets" (which is the problem my Plus has...

Ha, Ha, I will double check the page

Yes attached, only Larry's drawing locates Q10 where Q11 is and vice versa?

I am following Larry Pina's guide to repair a Mac Plus analogue board power supply, page 23, but I cant find a silicon controlled rectifier Q10 (CR400Y) or an equivalent on Mouser???

SOLVED. I dug out an Airport Extreme base station, plugged it into a spare ethernet port on my router and set it up in bridge mode with another wifi network, then plugged an Airport Express into my SE/30' ethernet port and it works fine. Many thanks for the help  :-)

Thank you for replying. (sharp intake of breath) I get some idea of the issues described in that document but certainly not everything, and I wonder if the problem is down to my router port-blocking AFP. And I can still move files around by FTP with Netpresenz running on the SE/30 when even...

I have a NetGear WNCE2001 (RJ-45  Ethernet to 802.11) WiFi bridge adapter connected to the ethernet card in my SE/30 and I can ping the SE/30 from a Classic connected to my internet router via an Asante EN/SC and a 10T hub.  I'm running system 7.5.5 on the SE/30 and whether using MacTCP or Open...

You can manually set a files type with the application that created it, or set another one if you wish, say to look at the code an image with Simple Text. I have also found it too but i’m not sure now whether it’s a PPC app. ;-/
