For those of us who owned older Power Macs with PCI slots, we'd install an ATA controller PCI card to take advantage of the faster and larger capacity IDE/E-IDE hard drives. Larger capacity SCSI drives were just too expensive to purchase. With your LC III, your options are limited and there aren't any inexpensive plug-in adapters to convert an IDE drive for use on a SCSI (I or II) bus. You should try to find a compatible 50-pin SCSI I/II hard drive, perhaps at ebay. Some years ago, you could find many SCSI drives listed for auction, but the supply dried up and the demand for them disappeared. During that time, I bought a number of them in different capacities - from 160 MBs to 4 GBs, which went into my assortment of older Macs. Just so you know, the Quantum 4 GB hard drive was the largest capacity SCSI drive (with that same 50-pin IDC interface) that Apple shipped in its computers. The last time someone inquired in one of the forums about SCSI hard drives, I decided to check ebay and was surprised to see how few were listed. The asking prices were probably 4 times more than what I paid for similar drives, years earlier. Scarcity drove up the price, far beyond the real value of the drives.
