ok time to update, my Mac is working fine except for doubled rows of horizontal lines. I tried to make connections as suggested by apm, but unfortunately I get no picture at all. It seems that Plus might be a bit different. Can anyone give me the Plus-specific  chips and pins  connections for...

JonP: any chance you could show the picture of this mobo fix? 

I've had many Pluses and none of them required recapping. Those THT caps are likely to outlive us.  I am 99% sure it's a ROM related issue.  I've had  the same pattern on my Plus without ROM chips.

I still have the same horizontal bars in the SE/30 which had capacitor nasty leakage despite having it recapped and replacement of the few chips plus fixing of broken traces.  IT happens  when I open the case and there is motion underneath the mobo, might be some bent pins which cause this...

the problem is 68000 cpu is too slow to render jpg files and probably png files. However the last ones might be better to load. So you need to find any browser that handles PNG files, dont care about CSS, java and such. Here's why: http://pici.picidae.net/ It makes a clever snapshot of the web...

hey Alex let me know if you want to swap an extra mobo for something else retro one day. Really like that MRoD store, thanks for mentioning it.

ok cool thanks!

Hi,  Sadly since Steve of Big Mess o Wires is not going to restock Mac Rominator, I've been wondering about my options. I have two Mac Pluses, one of them is without ROMs.  Is there any way I can copy existing ROM chips to file and give it to local electronic shop so they can burn some EEPROMs...

thanks will prepare a new cable and probe 5v on correct side with my meter, so it should be 4P4C instead of RJ-11? 

the only thing I found is this pinout. 

Hi, seems that it's lost. I've seen one on eBay, but considering shipping costs there's no way I am paying $40 for a simple cord!  I am aware of arduino solution, but I just want to use my Apple keyboard. Any way I can modify telephone cord? Charlie

wow, you just saved a few  bucks on this one... but so cool you showed this completely unaware of real computer's value minor some generosity :)  He might get a few burritos for a computer worth $100 for upgrade itself.

I have the same issue with my Plus, but it doubles the screen horizontally. Havent resolved it yet. But someone suggested checking certain traces in my old thread.  Cant find this post after forum "remodelling". 

Ok sorry, missed that. 

Can you elaborate on that? I can see no connection between this site and antisemitism. If you're referring to recent Warsaw incident blown out proportion by some news stations, I think that's not the right place to discuss it. If I were rude I could ask you a question - is children sexual abuse...

no it wont, changing pins wont do! This modification takes a lot of work. https://web.archive.org/web/20140312150842/http://mcbx.netne.net/hacks/mouse/index.htm

I am on the fence to be honest. While I like my SE/30 I've been thinking why I need one in my collection since I already have bunch of maxed out (in terms of RAM) Pluses.  I know that Unix, BSD and Linux distros need better CPU than 68000.  Ok, lets see which games and programs apart from web...

cool another se/30 saved from throwing to dumpster!

North Korea ;D
