Hard Disks (and controllers), Connectivity with PC

["Mr-T" <jonthorp@-no-spam-bigpond.net.au>]

Three years ago I was given an Apple IIGS by a school that was throwing them
away for scrap. Using X86 machines only, a IIGS was a really interesting
experience, but all I had was the machine and a few floppy disk drives (a 3
1/4" and two 5 1/4" drives) with GS OS 5.xx (I think). As far as I know,
this is a ROM1 GS with 4Mb of RAM (there's an extra card installed), with no
extra cards installed

GS OS is great, but I have to constantly keep changing disks every time I
want to run a program which does become somewhat annoying, but I wouldn't
mind doing that if I had more than the three or four programs I have on
disk.

1.) As I understand, there's a wealth of IIGS programs on the Internet, but
given my GS doesn't have any additional cards and I don't have access to a
Mac, is there any way at all I can connect the IIGS to my PC? Is there some
way I can connect the IIGS between the wierd communications port it has and
the communications port on the PC?

2.) Is there any way that I can get software onto my IIGS since I don't have
access to any means of getting even a terminal program onto my GS?

3.) I have many old IDE (ranging from 40Mb-4.3Gb) hard drives (and possibly
one or two SCSI - but they would be too big, about 1Gb). Is there any way I
can utilise these disk drives on a IIGS?

The hard drives are fine, but what about the controllers? Anyone know about
their availability in Australia? I honestly don't want to pay obscene
amounts of money for an old SCSI/IDE controller for a IIGS, so price is
definitely an issue.

Thanks for your help!
