    Buzzing noise from Apple IIe transistor?

    Heres an update, checking outputs, I’ve replaced C15 and C17, still not turning on

    Buzzing noise from Apple IIe transistor?

    Alright. Forgive my lack of knowledge, my multimeter has an Ohm option that beeps when continuity is found. Checking C9-17 does give numbers on the screen, but there isn’t any beeping. Would that indicate anything?

    Buzzing noise from Apple IIe transistor?

    Well, touching any of the capacitors gives me a volt rating of 0. I think something’s toast. Better to just replace all four of those capacitors? Unless I’m doing something wrong, I don’t usually use multimeters

    Buzzing noise from Apple IIe transistor?

    Thanks, I wasn’t sure if you meant the diodes on the psu or the motherboard, so I took photos of both. Another thing, when I lifted the psu to take photos, I heard a pop, and now the psu makes no noise when turned on. Can I hope that’s the fuse, or is this transistor dead :/

    Buzzing noise from Apple IIe transistor?

    Heyo, Per the subject, my Apple IIe won't turn on, and there's a buzzing noise coming from the transistor. Originally, the transistor was making a clicking noise, and the power led would blink on and off, but now its gotten faster and the led doesn't turn on at all. I've read a few posts about...

    Using Apple II as a dumb terminal?

    I didn't know about closing the screen utility. Unfortunately, there's a problem with my apple, again! It doesn't turn on, and the transistor keeps clicking, I think it's shorted. I'll open a new post for that, but if anyone has any suggestion, I'm all ears.

    Using Apple II as a dumb terminal?

    So I got ADTPro working, and I followed your steps. Terminal on my Mac is giving me the error, "Sorry, could not find a PTY". I've been using this cable, as the original reddit post said that this one worked (https://shorturl.at/JD4sy). Not sure if it's a null modem or a straight through.

    Using Apple II as a dumb terminal?

    Okay! I'm back. Thanks to Epooch for sending me a replacement jumper! Anyways, I used IN#1 at the basic command to test the card, that seems to work as the Apple SSC prompt can be accessed. I then used ADTPro, which doesn't work. My host computer says Request: Desktop Contents (the desktop is...

    Apple II psu potentiometer

    I’ve tested the rails as per Adrian’s instructions () and they all are within the correct ranges

    Apple II psu potentiometer

    Great, and once I do that would I need a multimeter or oscillator to reset the voltages? Or at least view them.

    Apple II psu potentiometer

    How would I do that? The hard drive I have in mind is an old sata drive with a 4 pin molex input for power

    Apple II psu potentiometer

    Ah shoot, thanks for that. Yeah, I’m not sure how to test that, so I would appreciate some help😖

    Apple II psu potentiometer

    Hello, I was cleaning a burst RIFA in my Apple II psu and I happened to spin this potentiometer. Just curious what its purpose is and if I made a mistake that can be fixed. Thanks!

    Macintosh Plus Custom Casing?

    Heyo, A while ago I had this grand idea to send my Plus out to Cali to have it fixed, long story short it came back with a cracked and mangled outer case. No I have just the guys sitting on a table. So, instead of buying a replacement case, would there be some possibility of making a new...

    Using Apple II as a dumb terminal?

    Oops! Apologies, I thought your question of being able to use adt pro was if I had the knowledge to, not if I had successfully executed it. I have it set up, but I haven’t tried it yet as unfortunately when I was pulling out the modem/terminal jumper block, I snapped a pin off ;( maybe come back...

    Using Apple II as a dumb terminal?

    I’m using the Apple Super Serial II card and yes, I can use ADT Pro. I set the card up using the manual as if it were using a printer, so SW1 is 0001011 and SW2 is 1001000 (1 is on, 0 is off)

    Using Apple II as a dumb terminal?

    I’m using this cable: https://www.amazon.com/gp/product/B000067RWK/ And running ls /dev/cu.* does give me the correct /dev/cu.usbserial I’m blindly following the reddit instructions, and I don’t know the inner working of the terminal, so if Screen would work better than Getty, how would I go...

    Using Apple II as a dumb terminal?

    I’m using a 2015 intel MacBook Air running OS Monterey (version 12.7.6) because the serial to usb drivers didn’t seem to work on a newer M1 Mac.

    Using Apple II as a dumb terminal?

    Heyo, I’ve been trying to use my Apple iie as a dumb terminal by following this helpful guide on reddit () However, it just doesn’t work for me. After the last step to type in the exec::: command, the cursor just blinks and Terminal on my MacBook is unresponsive. I’m using Proterm on my Mac and...
