[comp.sys.apple2] Cable question

dave@PRC.Unisys.COM (David Lee Matuszek) (05/17/91)

I have an old 5.25" floppy drive for an Apple II+.  It's beige, with a
ribbon cable.

I want to connect it to an Apple IIe.  (OK, actually a Mac LC with a IIe
emulator card, but that should be the same thing, right?)

I've been talking with a company that advertises in A+ magazine (I
forget which one), and the tech there says that a simple adaptor won't
work, because the IIe drives use an additional signal not used by the
II+ drives.  He says the drive will spin up and calibrate OK, but the
IIe will not see the disk.  He doesn't know whether there's a simple
workaround.  Not being a hardware person myself, neither do I.

Does anyone know whether this can be done?  Can anyone tell me the
difference between the signals used by the two drives?  (I won't
understand you, but I can pass the information on to someone who
will.)  Is there a simple known workaround, or it is known that there
is none?

This must have been a FAQ a few years ago, when the IIe came out.  I'm
hoping someone still remembers the answers.  Anybody?

What?

Now, assuming the //c disk interface is the same as the newer //e's
(my disk II interface takes the 20 pin flat ribbon cables), there
is no trouble hooking up an old disk II. All it takes is a little
adapter. I used a disk II on my //c for a while, until I got my
Unidisk.

Sounds like someone is trying to sell you something you don't need.

On the other hand, maybe the //e is different from the //c.
