:I purchased a old copy of Delphi 2 for a reaonable price. Will I be quite limited in what I can do with it? Can I run code from later Delphi versions or from this site?

Yes, you can run all DelphiLand's code examples and tutorials with Delphi 2.

: I read on the net somewhere that from Delphi 2 onward that they all work well with Win32 OS's, is this true?

True. Although probably you can't use some Windows API functions (Application Programmer Interface) that were introduced after Win95 (Win98, and later), because Delphi 2 does not have an "interface" for them (doesn't know that they exist in Windows). Don't let this scare you off, as you probably won't use any of the new API stuff for quite some time, they are only for the very "special" tricks.
Also you probably can't install the newest add-on Delphi components of which you can not obtain the source code, as they are written for Delphi 4/5/6/7. However, there's no problem for most add-on components *with source*: simply recompile them and most will work nicely with D2.

: At this time all this .Net and Web application stuff I probably wouldn't use anyway. I just want a program that I can write win 95,98,NT,2000 .exe's that can call other programs and control the I/O ports on my puter.

Delphi does not have any native components, nor commands or functions that directly drive the hardware, so programming I/O ports has to be done with "special" stuff. You might find some free I/O port code for Delphi 2, but not much. Don't wait too long searching for that stuff, as it's getting quite rare.
