    Macintosh Plus White bars issue

    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.

    Macintosh SE/30 and lines

    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 issue. All I need is to to take off and gently put on this aluminum port cover again. When it sits still in one place it's perfectly fine.

    Damage on SE/30 MLB?

    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.

    Plus ROM duplication

    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 for me? Last time I showed them the Plus motherboard they told be they wouldnt be able to read the ROM chips using standard Willem programmer. I have an ancient "Copy ROM" program, but it saves to a single .ROM file. IS there any way you can extract Hi and Lo roms from that single file? Any help would be appreciated.

    Lost Mac Plus keyboard cord

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

    Lost Mac Plus keyboard cord

    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

    Macintosh with 'sort of double screen'

    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".

    512k mouse == pc serial mouse?

    Ok sorry, missed that.

    512k mouse == pc serial mouse?

    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 just a random act of violence in your community, or just "standard thing" to you people?

    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

    Does the SE/30 live up to the hype?

    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 browsers require more than 4 MB and 030 while still running in 1-bit graphics mode. Any clues? To put in other words what are the "killer apps" that require SE/30 specs and wont run on Plus?
