Disk ][ Speed Testing - need troubleshooting advice

Submitted by apple2ee on February 10, 2009 - 9:54pm

I'm running Copy II plus v8.2 on two Disk ][ drives using an Apple IIe (I copied it over to the apple IIe disk using ADT). I suspect I have bad 5.25 disks that I mail ordered recently. However, I'm checking the drive speed to be sure. Drive 1 is successful in initializing the new disks 90 percent of the time. Disk 2 is almost never successful. Disk 2 sounds crunchier than disk 1 when it reads and writes and tries to init a disk. Disk 2 has been opened and checked for head dirt, it is clean.

Checking Drive speed with Copy II Plus, which version should I use?

Submitted by apple2ee on February 10, 2009 - 6:11am

I am going to check the speed of a Drive ][ connected to a standard Apple IIe. Does it matter which version of Copy II Plus I use to read the speed? I noticed there are a number of versions available. Which one should I try to use. -thanks

Also, when adjusting drive speed, how far does the speed screw need to be turned to make a noticeable difference? Barely any or alot? I don't want to over crank it on the first try.

Any other random speed tuning advice would be appreciated. THANKS.

Apple II PLUS tech Q on IC and power indicator light

Submitted by rocketscientists on February 9, 2009 - 3:20pm

Hi

I have an JAMECO 16K RAM card that is currently in slot 0 of my Apple II plus. It also has a ribbon cable that plugged into the IC location E1. Does anyone know what was the original IC that went in this slot? I need to replace the chip in to debug a couple of minor problems.

Also, my power indicator light is out (missing). I have the Apple II PLUS that has the power indicator button flush with the system. Anyone know what kind of bulb and voltage rating that went in there?

Disk ][ Drive 2 installation question

Submitted by apple2ee on February 9, 2009 - 7:28am

I recently installed a second Disk ][ drive in my Apple IIe. The first drive's ribbon was already clamped into one of the holes leading out of the back of the case, so I just fed the second drive ribbon out of another hole in the back next to the first one. I didn't have another metal clamp to secure the second ribbon so I just refitted the plastic tab that seals the hole with the ribbon coming out the side of it. It's not a great solution but the ribbon is fairly secure.

Need 5.25 floppy buying recommendations ...

Submitted by apple2ee on February 8, 2009 - 4:24pm

I purchased some Platinum 2S/DD 5.25 disks recently and they don't work very well with the drives. They work about 85% of the time but I get far more I/O errors from them than with my 25 yr old 3M 5.25" disks. Drive 2 can't initialize these disks either, but drive 1 can usually.

Does anyone have any recommendations on what kind of 5.25" floppies to buy for an Apple IIe and where to buy them?

-thanks

Apple II Plus Keyboard needed-- Help!

Submitted by rocketscientists on February 7, 2009 - 11:38pm

Hi,

I am looking for an Apple II PLUS keyboard. It does not have to be functional, or it is but has some broken keys. I need to repair my own keyboard which I recently broke one of the keys.

The Apple II plus keyboard is a built-in keyboard that has an attached keyboard encoder card underneath it. All I need at this point is the keyboard itself (sans the daughter card). Does anyone here have such item laying around?

Need Static Electricity Prevention Advice

Submitted by apple2ee on February 3, 2009 - 8:29pm

My home is rampant with static electricity discharges. Every time I walk across the carpet I'm building up a charge. I'm worried about shocking my Apple IIe to death every time I touch it. It's a huge problem. Are there any products I can put under my Apple IIe or around it to protect it from the static electricity coming from me? I remember a mat I used to have under it back in the early 80's, but I'm not sure what to buy now. -thanks

Apple IIgs Noisy PSU

Submitted by TheKisho on January 28, 2009 - 6:05am

My power supply is audibly noisy. It's the loudest power supply I've come across. Is it typical for an Apple IIgs power supply to be noisy? I mean at a level and pitch to make your ears ring after about 30mins to 1 hours use or deaf if you used it for 8 hours a day constantly. Okay maybe I'm exaggerating [not death after 8h, but ears ring after 1h] it's really annoying though. This is also with the case closed.
