Even PCs have no floppy drive connector.

Exception ...

Those early PC motherboards which were designed using a "Super I/O" chip,
made by ITE and many other Asian companies.

This chip rides on the PC's "low pin count" bus, which Intel-based Macs
also have, and converts that to:

1) standard 34-pin floppy drive, and

2) standard 40-pin ATA bus which supports two ATA drives, and

3) RS-232/RS-422 serial port, and

4) "Centronics-type" parallel port, but using IBM's "Centronics-type" pinout.

These "Super I/O" chips largely disappeared with the 5-Series motherboards
from Intel and many others, but were considered essential for 4-Series
motherboards, and earlier ones as well.

The BEST solution for accessing floppies on a Mac is a Fujitsu or equal
USB floppy drive.

Incredibly enough, these even work on PCs, and can be bootable if the PC
motherboard/BIOS supports booting from a USB device.

On a "Hackintosh", floppy booting is even possible by selecting
"USB-Floppy" from the boot device selection menu.

Alas, a standard floppy only accommodates 1.44 megabytes of info, and most
PC BIOSes these days are 8 megabytes, a little more or a little less.

No. There is no connector on the board for a "normal" floppy. I've seen
some folks shoehorn it into a USB enclosure in one of the 5.25" bays and
connect that up, however.

Regrettably, probably only from another Mac of the same model.

Add normal floppy drive to Power Mac G4?

2016-07-22 Thread JackMacWindows
Hello,
I have an old Power Mac G4 Digital Audio, and I would like to add on a 
floppy drive to read floppy disks I may find floating around. So I 
purchased a floppy drive on eBay, but I realized that it has a normal 
floppy drive connector. Is there any way I could connect this drive to my 
G4 without buying a new drive or making this external? I did not get this 
Mac with a Zip drive, so I do not have anything to replace in the 3.5" bay. 
Note that I have a budget of $25 on this floppy drive project.
Also, if I can get this working, is there anywhere I could get a Zip drive 
bezel? I would not like to have to a) drill into my blank bezel, or b) have 
no bezel on.
Thanks,
Jack
