Apple iic keystrokes registering continuously

Submitted by j2theLj on September 18, 2022 - 10:05am

I recently got an Apple iic with a fault; in Basic any last registered keystroke will register continuously until a new one is made, then that will register continuously. I only have the one machine and can't trouble shoot by swapping parts - what is the most likely culprit here? See attached video. Thanks

ProTERM 3.1, Offline vs. Online

Submitted by lee317 on September 13, 2022 - 2:45am

I have been playing around with WiiModem232 and ProTERM 3.1. The WiiModem232 needs to be addressed directly from the terminal to enter Hayes AT strings. Although nowhere in the official ProTERM 3.1 documentation does it talk about this, apparently pressing command-T puts the program in "Terminal Mode" and allows the user to send commands directly to the serial port.  My question is, how do I exit this Terminal Mode?

Cloth covering CRT

Submitted by 8BitHeaven on September 12, 2022 - 11:23pm

I have two monitors (an Amdek Color I and an Apple  Monitor /// ) both are missing the antiglare cloth which covers the screen. I don't even know what to call it to google it...  Does anybody know where to get replacements? 

 

And yes, I am well aware of the dangers of working inside the CRT.  I have worked on many, I am still alive and plan to stay that way.

Apple 2 Plus Color Burst goes to h$%@ In Circuit

Submitted by kirkj on September 6, 2022 - 7:58am

Hello there. First time here, Noob.

I have an apple 2 that is driving me crazy. Problem is that i dont get color in HRG. I DO get color in GR.

I have studied the circuit and traced it out with a scope (best i can). Here is what i see.

The clock is spot on.

The divide by 4 at chip B1 is producing perfect 3.58mhz

Im getting 3.58mhz all the way through B13 and B12

the burst signal then goes to a 1k resistor before entering the 'color killer' portion of the circuit.

I think I know what’s wrong with this iie...

Submitted by insanitor on September 4, 2022 - 10:15am

While browsing on eBay looking at iie motherboards, I found this listing...

The seller says that when it's turned on, nothing comes on the screen.

Maybe it has something to do with the missing LS125 chip?

https://www.ebay.com/itm/195259271348

Oops!

Time for someone here to get a replacement iie board for cheap.

The seller is using the, "or best offer" option.

Apple 3.5 floppy no longer working since upgrades

Submitted by Lysh25 on August 29, 2022 - 5:12pm

I upgraded an apple iigs with Rom 1, 8mb ram and microdrive turbo but since upgrading my floppy drive no longer works. It is plugged into the back as it always was but now doesn't even light up. Is there some configuration I need to do in the microdrive?

 

I am new to this and not sure what the issue is. Any help is appreciated.

 

Thank you
