    Astec LCII PSU connector to the logic board

    I ended up buying a package of two 8 terminal Molex plugs for about $4 at my local electronics store (Greenbrook Electronics in New Jersey). I removed the corroded terminals from the original 7 slot molex and I'm going to use the new ones that came with the 8 slot connectors. This way I still...

    TDK LCII PSU recap issue, ticking. Doh!… Nevermind

    I didn't realize it had to be plugged into the board or it ticks! I plugged it in, it seems to work! I just recapped my other LCII PSU, a TDK this time. It was completely dead. Now it ticks in triplets (123-123-123, etc.). It's very faint and sounds as though it may be coming from the...

    Astec LCII PSU connector to the logic board

    Does anyone know if there's a part I can get to replace this connector? Mine is so corroded, it's literally falling apart. I found all these little flat corroded pieces of metal in the case not knowing what they were, turns out they're the term connectors inside this plug. I just recapped the...

    Recapping a Mac LCII PSU - replace a 180µf with a 220µf?

    Hi, I'm recapping my LCII PSU by Astec. I ordered the Astec recap kit from Console5. The big cap on my board is a 180µf 400v nichicon while the one they sent me is a 220µf 400v. I know with voltage I can go higher but what about micro farads? Not sure how to test the old one to see if it even...

    What's this for?

    Apparently, it's an IC lifter, no idea why precision tweezers wouldn't be better though.

    What's this for?

    It came with my new hot air station. No clue what it is or how to use it.

    RAM ID guidance?

    I have a couple static bags of RAM chips (as I'm sure we all do) that leave me sometimes guessing what they are. They all have some sort of ID on the individual chips but it's usually not very telling. If I see a "1024" I can assume it's a 1MB chip but but speed is still a guessing game. Some of...

    When will v1.1-a kits be available? I'm not seeing them on the sealer sites yet.

    Help diagnosing a Mac Plus

    Thank you all, I now have a working (second) Mac Plus. I adjusted the voltage 11.98v and 4.99v in the floppy port, adjusted the screen cutoff, now I just need to figure out how to move the screen over a smidge so it's centered.

    Help diagnosing a Mac Plus

    Looking up how to adjust the voltage now. I fired up a working SE I have and the FloppyEMU is showing white screen there too. I think the EMU screen came unseated. It's kind of a known problem. I'll take your advice and turn the voltage up a tad, I'll let you all know how it goes. Thank you...

    Help diagnosing a Mac Plus

    Spoke too soon! I kept swapping out RAM and got 4 chips that worked. It boots off the floppy disk now! Now I have to figure why my FloppyEMU still has a white screen. :( Maybe it's the voltage coming out of the floppy port? it's about a half a volt low but not too bad, right?

    Help diagnosing a Mac Plus

    I put four 1MB chips in and I got a much better screen and mouse cursor. A little crooked but I'll fix that later. Double checked the 256k resister and it's clipped. Now, the known good floppy drive and boot disk are just ejecting like something is wrong with the disk. this disc will boot a...

    Help diagnosing a Mac Plus

    I'll do some experimenting. I hadn't even thought of that. 2 of those chips say "DO NOT USE IN MAC SE". I'll have to go through all these and see if something works:

    Compact Mac Flyback alternatives?

    I have a MacPlus PSU that is starting to make that high pitched tone from the flyback. Is there a way to doctor it up before it fails? The epoxy seal looks intact and no corona appears in a dark room. Floppy port voltage looks good too.

    Help diagnosing a Mac Plus

    I've been trying to resurrect this Mac Plus for weeks now. At first I thought it was the PSU because it was so mucked up. After cleaning it up, reflowing the solder joints and measuring the floppy port volts, it seems OK. Here's the next issue: When I hit the power button I get a beep (all...

    Compact Mac Flyback alternatives?

    I'd buy a few of them!

    Compact Mac Flyback alternatives?

    I don't know a lot about electrical type stuff but I'd bet there are probably some other options out there for these flybacks on compact Macs with 9" screens. As these Macs get older and older and CRTs and flybacks probably completely out of production by now, it's getting harder to find...

    Interesting solution for LocalTalk to Ethernet bridge

    I just bought a G3 233 for $100 that I'm gonna use with Vicomsoft Router to connect LocalTalk to Ethernet, plus it has SCSI and I can get a cheap PCI usb card to bridge SCSI/USB. There's even an internal Zip dive. And it's still cheaper than an Asanté solution!

    Interesting solution for LocalTalk to Ethernet bridge

    If I could find one for $20, i'd buy it too! I'm pretty much off of buying things on ebay lately. Inflated pricing and misleading listings. "Here's a piece of paper I found in the garbage with an Apple logo on it! Only $5,000! L@@K Steve Jobs!"
