II+ won't load any disks

Submitted by Link on June 25, 2012 - 12:11pm

I have some known good disks that will load fine on one of my II+'s, but won't load on the other with the exact same floppy drive and card. The drive just spins endlessly.

Since the disk subsystem isn't to blame, I'm wondering if this is some kind of RAM or power issue, or perhaps something else on the motherboard. I could go about replacing ICs one by one, but before I do that, I wanted to see if anyone knew of any immediate "things to check" for this particular issue - bad ICs known to cause this, etc.

Anyone have a Rhodes CHROMA interface card?

Submitted by epoxy2600 on June 21, 2012 - 2:02pm

Hi all,

I'm not only a big Apple II fan, but also love old music synthesizers/keyboards. I'm soon to be the new owner of a Rhodes CHROMA synthesizer from 1982; this instrument was one of the first that enabled interfacing with the Apple II to allow sound creation and music composition.
To do so, one needed a CHROMA interface card installed in their Apple.

Question about the Apple IIGS

Submitted by Clyde1992 on June 9, 2012 - 4:39am

Forgive me, in advance, if the answer to this question is obvious. I am new to the Apple II series of computers.
I recently acquired an Apple IIGS, on Ebay. After reading various manuals on the web, I have learned the functions of most of the ports. However, the function of one particular port eludes me: a rectangular hole on the far right of the computer (labeled "13" in the following picture).

Could someone enlighten me as to the function of this port? I have found no information about it.
