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?

Oops!

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

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

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

Videx Videoterm jumpers

Submitted by bradleyb on August 24, 2022 - 2:57pm

Does anyone have a copy of the Videx Videoterm manual which includes Figure 9, which is supposed to document the solder jumpers?

The only scanned editions I've been able to find do not include that figure.

 

Barring that, does anyone know what jumpers X5, X6, and X7 are supposed to do?

Apple III case screws

Submitted by guibrush on August 19, 2022 - 11:51am

Hi, to finish the restauration of my Apple III I'm looking for the screws that hold both the power supply and the motherboard plate under the case.  As I'm in Europa, I don't find them. Can someone point me to the right direction? Thanks :-)
