I got the analog board removed from the computer. I tried the alcohol method, and it seemed to work. I was able to get the neck board removed without any problems. The real pain was actually the anode cap on the side of the CRT. It took a good 10-15 minutes for me to get it removed. I hope it...

I read something on one of the FB groups about a diode (specifically DP6) going bad, which can cause issues you're noticing. It's a MB4 1045 S. Perhaps that diode has gone bad?

Thanks, @erichelgeson. The video helped a lot. When replacing the board, do you feel when the board is completely on?

So, if I'm understanding this correctly, it shouldn't take much force at all to remove the board? I guess I'm not understanding the "keep motion perpendicular to the neck board" part - you just pull straight up on the board, right? Do you need to wiggle back and forth slightly, or can you just...

My main worry is accidentally breaking the nipple on the tube. I just pull straight up on the neck board, correct?

I've heard people mention that you should cut the glue. I even noticed in the service manual for the Classic/C II that it says you need to cut the glue using a craft knife. But, then again, I'm guessing after 29 years the glue probably isn't nearly as strong as it was when new. So I should just...

Strange question today... I found someone who can recap my Classic's analog board. I noticed there is a little bit of hot glue keeping the neck board connected to the CRT base. They suggested I could use some rubbing alcohol to dissolve the hot glue, so I don't have to worry about using a box...

This kinda goes along with the MacPaint/PICT question I had in a separate topic - but can modern versions of Word open documents written in Word 4.0? That's another thing I'd like to try once I get my Classic back up and running and can get a FloppyEmu for it. My Classic came with both Word 4.0...

I still use an iPhone 6s on a daily basis. I've been thinking about possibly upgrading to the SE (2) and letting my dad use the 6s to replace his cheap/flaky Motorola Android, but I don't know. The 6s is still a really competent phone... I'd say it's probably the best phone I've owned. But that...

I knew that machine looked familiar because I remember the Micah sticker on the front. It showed up for sale a while back, but if I remember it was out of my price range. (Though not badly priced for a 128k/512k machine.) Plus I wanted something a little bit newer to start my collection with. I...

@TAinKC I looked at your username - do you happen to live in the Kansas City area? I remember someone had one of those Micah Macs up for sale here in Jefferson City a while back but I passed on it.

In the photos I took of the machine before reassembling it last Friday, none of the electrolytic capacitors appear to be domed or leaking. Obviously, that doesn't mean anything. If the caps are not causing the issue, what else could be causing the issue? My electronics troubleshooting skills is...

Should simply having the analog board bring the machine back from the dead? When I got the LB recapped, I was considering also having the AB recapped. But I decided against it because it wasn't showing any signs of failure, and I wanted to avoid/put off having to mess with the AB because of the...

That was precisely my speculation, but unfortunately I don't have a multimeter to test any voltages on this machine. My guess is that there simply isn't enough voltage for the hard drive to spin up. When I boot into the ROM operating system and insert a floppy, the drive's current brings down...

I will try to remove the anode cap by hand once I can cobble together a tool to discharge the CRT. An flathead screwdriver (with an insulated handle) and an alligator clip running from the screwdriver to the metal chassis should be sufficient to discharge the CRT, correct? (That's what I've seen...

Thanks for the tip on the logic board molex connector. However, I normally have the computer set normally when I reinstall the logic board, so I can't really put my hand below the logic board. As for the anode cap, I always thought you could simply squeeze the fingers holding it in place from...

I already know to discharge it at the anode cap. I've heard most CRTs from this era (should say the driving circuitry) are pretty good about discharging the CRT itself, but never a good idea to rely on that. When reinstalling the logic board in this machine, I was careful to keep my hands in...

Thanks. I'll find a video on the suction cap... I've seen some 8-bit Guy videos where does it but it's been a while. I'm mostly concerned about the neck board, given that the neck is the weakest part of the tube and thus the most prone to breaking. I recall seeing what appears to be hot glue...

Ever since I received and installed my freshly-recapped logic board for my 1991 Macintosh Classic, the machine has been reliable and working wonderfully. (Besides the 1-2 minute delays on startup, where it displays a pattern on the screen. It supposedly is something related to the ROM.) I should...

That machine has came a long ways. Great job on the restoration!
