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. ;-/

It took about a minute to transfer 828KB to my Classic with Appleshare and half that with FTP

I can't find a piece of software I found very useful,  I think it was called Sets its type (maybe all one word, it might even be of Japanese origin?

Oops! Yes I've also just read that on EverMac.com but thanks for the reply  8-o

Hi, Checking out my Mac Plus I spotted a cut resistor on the logic board. Why would someone do this?

My error, I had the Gateway IP address wrong in MacTCP So I put my routers IP address in the Gateway box and placed an alias of MacTCP Ping in the startup folder to give my Mac a presence on the network, and this works and also retains my setting of Alternative Ethernet in the Network control...
