Hello. I recently picked up a Macintosh Plus. Since a Macintosh Plus can run up to 7.5.5, wouldn't this mean that if I was to put system 7.5 on the Mac that it would be able to read (800k of course) PC floppies?

Macintosh Plus PC Compatible?

PC floppies of that vintage were 720KB, not 800KB. I doubt the Plus' floppy drive will be able to read them, but it's worth a shot.
When I upgraded my SE to System 7.1 last year, it was able to read formatted DOS disks, but they weren't 720KB, just 1.4MB.
In addition, I would refrain from running 7.5 on a Plus. You're really going to tax the 68k processor. If you want to use System 7, install 7.1 max.

That should pretty much explain it.

Here's the salient point:
No matter what System version you run on a Mac Plus you cannot exchange floppies with an IBM machine without buying extra hardware. The Plus is equipped with the original IWM disk controller (used in the Macintosh 128k, 512k, Plus, II, and the first batch of SEs), and this controller is *incapable* of reading or writing MFM-formatted floppy disks. (And likewise is incapable of writing floppies which can be read on a PC equipped with a normal floppy controller.) And this applies whether or not you're running Apple File Exchange software.
In other words, to get data onto a disk readable in 400/800k only machines you pretty much have to have a newer Mac as a go-between.
