Apple 5.25 Drive making an occassionally horrid noise

Hi All, I'm new here and thought I would finally ask this question.

I have an Apple 5.25 floppy drive that makes an occasional click, and simultaneous higher pitched noise, compared to normal drive operation, that results in a floppy read failure.. it happens with multiple floppies that I know are tested good floppies.. and it doesn't happen with every floppy I boot off of.. it's currently daisy chained off a 3.5 Apple floppy drive, and then to my IIGS..

Random Numbers and Lemonade Stand

I was looking over the program listing for Lemonade Stand, and the following line has me confused:

2230 IF RND ( - 1) < .5 THEN 2233

It seems to me that RND ( - 1 ) will always return 2.99196472E-08, and therefore it can never be < .5. Or am I not understanding how the RND command works?

Apple II Power Supply Breakdown

Hi everyone,
I remember reading somewhere, and I'm sure it was on this forum, a breakdown of the Apple II power supply that spread over a few days, and was very detailed.
I can't seem to find it. I'm probably just looking in the wrong place.
Thanks
Martin

What 5.25in disks for an Apple ii Europlus?

Hi

Please forgive what might be a stupid question, but I finally managed to resurrect my machine and need to purchase some extra floppy disks for it (it uses the original Apple drive that came with the machine). Is it OK to try HD disks in these machines, I have read warnings that these can cause issues in old drives, so should I only look for DSDD disks? After all the time to get it going, I don't want to make a bad choice on disks.

Thanks for any guidance.

Karel the Robot disk image?

In high school during the mid 80s, I used Richard Pattis' Pascal primer 'Karel the Robot,' and although I've never programmed in Pascal, the lessons learned have stuck with me since. Several months ago I picked up a copy of Pattis' companion book and found it to be a thoroughly enjoyable read!
