I picked up a mostly complete Apple IIGS setup and finally snagged a 3.5" floppy drive for it, with the intent of setting up GS/OS on it. But I have a few questions about it:
* First off, there's an expansion card that isn't technically an expansion card (it sits in one of the openings in the back, but it plugs into the GAME port on the motherboard rather than an expansion slot,) and it has a CAT-5 connector and two RCA jacks - just what in blazes is this? I kind of figured it was an old acoustic modem until I confirmed that it was actually a CAT-5 connector and not a phone jack, and now I have no idea what it could be. An Ethernet card for the IIGS? If so, why the RCA jacks? Or do the RCA jacks mean it's a stereo modification, and if so, what purpose does the CAT-5 connector serve?
* Second, I need a hard drive to install GS/OS on, since the floppies I have are unreliable to the point where you pretty much need to re-initialize them every time you drag them out of the closet - not suitable for long-term storage, obviously. I have a 68-pin SCSI internal hard drive I got for free, but I'm trying to figure out how to hook it up to the IIGS. There's a long expansion card with a DB-25 connector on the back, which I gather is a SCSI controller, so I think I'm good on that front, but I need a 68-pin SCSI drive enclosure, and the proper cables with which to connect it; can anyone help me out as to where I can get these for a reasonable price, and whether it's more complicated than this or not?
* Finally, although 1.5MB of RAM is a nice chunk for a hybrid 8/16-bit machine, it'd be nice to beef it up to the full 8MB, and at some point in the future, it'd be nice to get an accelerator - can anyone tell me if there's a cheaper way to do this than buying the requisite items from www.reactivemicro.com?
