====== SCSI-IDE converter ======

Most classic Macs use a hard disk drive as their main mass storage medium. Some of the latest 68k Macs and the majority of PPC Macs use IDE harddisk drives. The majority of 68k Macs uses SCSI hard disk drives of a kind not in production any more, but. An option to replace a defective SCSI harddisk drive is the use of a recent IDE harddisk drive in combination with a SCSI-IDE converter / bridge device. This allows to use almost any IDE harddisk drive just like a common SCSI harddisk drive, with a jumper table to set SCSI ID number, termination, parity etc. Usually the device will be mounted piggybacked onto or below the IDE drive. Different makes are available in 3.5" and 2.5" form factor. Some devices protrude a bit in lenght, so it might be neccessary to adjust the mounting position slightly.

===== More Information =====

In case you look for an alternative have a look at the following article in this wiki: [[scsi_hard_disk_replacement_options|SCSI hard disk replacement options]]. Because IDE technology will reach end of life, as well, it might be useful to consider an [[IDE-SATA bridge]] solution.

===== Using a PowerBook as a Peripheral =====

In case you have an unused PowerBook, consider using it as an external drive adapter or media reader. Follow suggestions in the thread [[https://68kmla.org/bb/threads/the-ultimate-scsi-accessory.14177/|The -ultimate- SCSI accessory]].

=====External links=====
Several products to support vintage SCSI systems are available. Some are developed for this purpose and are in production, currently. Some of the products are intended for use in recent server arrangements, to provide a "low cost" alternative compared to recent high speed SCSI drives, which needs not to be a low cost solution in a hobbyists terms. In some cases one might need to get an additional passive adaptor plug to provide pin compatibility with older SCSI connectors (more or smaller pins to 50 pin IDC). Some of the following links lead to product pages of products probably not in production any more. Manufacturers might have "end of life" listed items in stock, still. In case of demand contact the manufacturer and ask for a quotation.

If you have recent information about additional devices or availability, update this page, please.
