Apple II

Apple Monitor II recently stopped working

I've had my original apple iie and Monitor II since I was a teenager.  Its been working great all these years until the other day a friend asked about it and I booted it up. The computer sounded fine but the monitor display was having issues.  I finally got it to display after tweaking the knobs and then shut it down. Now I tried to use it again and the power light is on the monitor but I do not see any video being displayed. I tried adjusting brightness and contrast but do not see any image.

Hi there,

 

I'm on my tedious task to restore an IMC-2001 (Taiwanese Apple ][ and CP/M clone) to working order.

Apple II Plus won't boot (no beep, screen full of squares)

Hi all, me again. I am really appreciative of everyones help with things so far. Unfortunately one of my problems got worse! 

 

The machine has never liked sitting since trying to resurrect it, if I leave it overnight unplugged, the next day it will often fail to start without fidding.

5.25” Floppy

Howdy folks,

I've got a 5.25" floppy disk that used to just boot up in BASIC with a home made loader. At some point, it just stopped working. Side B works, though.

 

What is the best method that I can go about making a backup of this disk in its current state and then dissecting the data in hex... or something?

 

I am hoping to either recover what's left, figure out what got corrupted, or simply figure out the names of the programs that were on Side A. 

 

Thanks for all your insights!!

Apple //c monitor transformer replacement

Hi all,

 

One of my apple 2c monitors have a faulty AC transformer. The secondary coil is open. That's a 16V AC one. I'd like to replace it, it won't be identical but as long as it fits...

The original one is 60x60x50mm. The ones I can find online are 60x50x32 but only 20W. According to the schematics, the 16VAC is a 1A line so that's 16W. 20W transformer feels a bit tight. But all listings I can find online show the same dimensions.

 

Are there any options anybody could think about?

Thanks!

Videx Videoterm clone, no display output and no beep. Help? :)

Hi all, I am having some issues with my Unitron 80 column card (Videx clone). The machine was sat for 30+ years so I have no idea whether it had any pre-existing issues, but lets assume not!

Apple II Memory Expansion Card problem

My Apple II Memory Expansion Card (which has 256KB onboard) is not detected by ProDOS as a RAM drive.  It's presently in slot 4 of a Platinum //e and when I run Copy II Plus to format it as a ProDOS block device it succeeds but when I access the drive it says it's not recognizable as a DOS 3.3 or ProDOS device. I can verify the drive using Copy II Plus and it appears to be the right volume size (512 ProDOS blocks).

 

I've tried replacing the RAM modules with known good one's but that hasn't made any difference.  Any ideas ?

*Newly acquired box-fresh Apple II Plus! || Project log + newbie questions*

 

Hi everyone! I came across this forum when searching regarding the keyboard on my Apple II, and I found this helpful thread about converting to Cherry MX keyswitches. https://www.applefritter.com/content/cherry-mx-datanetics-dc-51-keyboard-switch-adapter

 

So I figured I might as well sign up and say hi. :)

 

I recently acquired this early Apple II Europlus (European Plus variant) which had been sat in its original box for over 30  years!

Dim/fuzzy output on IIe

Just picked up an Enchanced IIe, and it has a wierd problem - pretty low video output, and a bit fuzzy, connected to my Apple Monochrome monitor. My other IIe is crisp and much brighter. Any idea where to start troubleshooting?
