    Katheryn's Macintosh SE/30 saga

    Yeeeaaah I still get a black screen. Could anyone give me any ideas as to what could be causing it specifically?

    Performa 475 logic board seems ok after 30 years

    i have a manual inject floppy drive i could sell to you for a good price, but i need to make sure it works

    Katheryn's Macintosh SE/30 saga

    Okaaaaay, I think I found my issue. It's the fact that I didn't clean the board like I should have. The solder paste seemed to have stayed near the contacts where I applied it to for putting my components on, and I had to clean it off with IPA. Don't know if it works yet but I think this is the...

    Yes those would be UB/UC12.

    Katheryn's Macintosh SE/30 saga

    Okaaaaayy, I may have a suspicion as to why it doesn't work right now. At one point I had soldered on one of the two SN75175DE4 chips that was the only one surviving, and recently I removed it. Can't remember where I put the chip when I removed it and the second one was damaged because of...

    Katheryn's Macintosh SE/30 saga

    If you'll please excuse the RAM slots (I got combined slots, and tried cutting them in half and ultimately screwed up), here's what my board looks like. Anything that I did wrong? I know it does need a good cleaning but I'm not sure what would be best right now. Yes, the SWIM is not installed, I...

    Katheryn's Macintosh SE/30 saga

    So out of paranoia I replaced all the RAM muxes and a few of the logic gates, and now I get a black screen... I also don't get a little 'pop' from the speaker when I turn it on, so I suspect the power supply is going bad? I know I didn't do a full recap on that...

    I'm using the stock ROM SIMM.

    Katheryn's Macintosh SE/30 saga

    Thanks, guys. Right now I have almost everything on the board, and everything required to get the machine to start. Only problem? It has a horizontal B&W line pattern so theres a chip or 2 that might be dead. Are there any specific chips that cause the simasimac or this specific pattern to...

    Katheryn's Macintosh SE/30 saga

    Thanks! I tested the paste I bought on a scrap motherboard's BIOS chip and as soon as everything went together I knew this was going to work beautifully. Obviously it won't look the neatest, but it seems like I can get this to work! Also... wasn't there a fix for artifacting on these SE30...

    CircuitBored's Overclocked eMac!

    Congrats on getting ahold of one of the greatest AIO macs of all time! I have 2 working eMacs, a 1.27GHz OC'd 2003 model running 10.4.11 and 9.2.2, and a 1.92GHz OC'd 2005 model running 10.4.11 and 10.5.8. Both of them are solid machines and I love using them!

    Ended up removing the PLCC sockets for the FPU and GLUE that I soldered earlier. I know those chips are good so there wasn't any point in doing that.

    Mac Mini 10.2 1.5GHz OC to 2GHz

    WOW!! I mean, it's not too surprising since the 7447B actually seems to cap out at 500MHz over the chip's rated clock speed with overclocking and overvolting. Some of you already know I got a 2005 eMac to run perfectly at 1.92GHz with a vcore of 1.375V. And... it still works 4 years later!! You...

    I feel more confident in soldering the PLCC chips directly. I got some better solder paste and I must say... it's much easier than installing PLCC sockets on EVERY chip! Just got the ADB chip and the 65C22s installed. May not look super even, but I touch up any bridges or missing joints as...

    Same, I'm very proficient at it myself. Done it lots of times.

    Good point, I'll definitely look into getting one of those!

    Rescued what I thought was a Mac II

    I just found out about this thread. I seriously envy you. I'm aspired to rescue stuff again, but every opportunity I have doesn't seem to work out. ;_;

    Katheryn's Conquests!

    I guess the fact that I paid $140 for one that required all of the caps to be replaced. Thankfully it was cleaner than other systems I've seen with more severe leakage.
