Apple //c Blown fuses.

Submitted by DistantStar001 on March 14, 2021 - 3:57am

So My //c just up and quit on me a few weeks ago.  Would have gotten to it sooner, but I had to replace my multimeter.  However, now that I have one again, I was able to trace at least part of the issue to a partially blown fuse in the power supply.  It's not completely blown, as I do get some continuity across it, but there's a lot of resistance and it was only putting out about 0.2 volts.

Hi all,

 

Just wondering. Does anyone have any information available on this video card.

Looking for a specific book of BASIC games

Submitted by Kyle6502 on March 11, 2021 - 3:50pm

For quite a while now I’ve been looking for an old book of Apple II games I used to check out from the library when I was a kid. It had a Space Invaders clone in it, and it was just about the only Apple programming book I've seen which extensively used sprites in its programs. Several of the games had sound effects routines encoded in DATA lines. But I don’t remember the title. The font was tiny and the programs were very long, and I think the cover was yellow, but my memory of it has grown hazy. Anybody know what this book was?

Apple IIC floppy drive can read.. but not write floppy

Submitted by devtordins on March 10, 2021 - 4:56pm

Hi, I have a very strange problem with an Apple IIC.  (To better understand the issue I attached 3 videos)

Initially I suspected the problem was the drive, so I bought a new one but got the same behavior (Heads cleaned on each one).

I can read, but not write or format floppy (by using ADTPRO). I also tried to load DOS using ADTPRO and execute the command INIT HELLO, without no success.

Disk ][ Interface Card Error

Submitted by appleiiapple on March 10, 2021 - 1:30pm

Well, I did something stupid today.  My apple IIe was powered on and I removed the Disk ][ Interface Card.....  Now the card will not allow the system to boot, green horizontal strips.  Remove the card no problem.  What would be fried on the card?  I can't figure it out with my basic multi meter test.

 

Thanks

Anyone parting out Apple DISK II floppy drives?

Submitted by Verault on March 9, 2021 - 10:58am

I was working on a short stack of Apple DISK II floppy Drives I marked as bad yesterday when I came across one that needs a new read/write head module (rides on the rails and has a wire connector lead to it. This one got eaten by mice but the chassis and boards are good I want to get it working again, its an early model with rainbow ribbon cable.So if anyone has a read head from a Disk II they are willing to sell please send me a message. Thanks!Mick

Need help identifying expansion cards in Apple IIgs

Submitted by markpx on March 9, 2021 - 10:16am

Hi,

 

I am looking at purchasing this Apple IIgs ROM01 system. Since I am new to the Apple IIgs world can anyone help me identify the cards installed in the system. This is this only picture I have of the motherboad. I have asked the seller but I don't think they are familier enough to ID the cards.

 

I know there is a memeory expansion card in front slot 8, but the others I have not idea. The card that concerns me is the card having the cabel soldered to  the Number Keypad header. Any idea what this card is?

 

Many thanks for any response.

Why Not the DIsk /// ?

Submitted by Timelord on March 8, 2021 - 9:34pm

This is a speculation thread, and surely something for those who want to discuss hypothetical stuff:

 

In 1982, Apple released the //e, knowing that the /// was dying. At this time, they had a large inventory of Disk /// units that were unsold.

 

Why did they never make a Disk /// controller card for the //e?
