XT-IDE Information

The XT-IDE is an 8 bit ISA adapter for attaching modern(ish) hard drives, DOMs, and CompactFlash to the ISA bus. When paired with the XT-IDE Universal BIOS, it allows IBM PC compatibles to boot from IDE drives otherwise not supported.

The Glitch Works is currently supplying XT-IDE rev 4 boards, parts kits, and assembled units for hobbyist use. Please visit our Tindie store or contact us to place an order! If you would like to run your own boards, all relevant KiCad files are available on GitHub.

	XT-IDE rev 4 After assembling many XT-IDE rev 3 boards, there were a few tweaks required to make the layout a little cleaner and ease assembly. Alan Hightower reported a race condition when developing his NetPi-IDE interface, which revision 4 corrects. Silkscreen is standardized and improved, and extra test points were added for Slot 8 Support installation.
	Slot 8 Support on XT-IDE rev 2 Part of the purpose in provinding Slot 8 Support as an optional daughterboard was to allow it to be added to other revisions of the XT-IDE. Installation on XT-IDE rev 2 is almost as simple as with later rev 3 boards, and works with all of the rev 2 features -- ROM, IDE, and serial port.
	IBM XT Slot 8 Support for XT-IDE The IBM 5160 PC/XT has eight ISA expansion slots, but slot 8 has slightly different electrical requirements. As a result, many boards do not work in slot 8, and those that do usually require a jumper to enable/disable slot 8 support. While the XT-IDE rev 3 was designed with slot 8 support omitted, I decided to design a daughterboard to provide it. In the course of designing it, I was also able to apply it to the earlier XT-IDE designs!
	XT-IDE rev 3 When a request for assembled XT-IDE boards came up on the VC Forums, I took the opportunity to make some changes and improvements to the XT-IDE rev 2 design. Mostly a board respin, this project's goals were to make the XT-IDE easier for hand assembly, more self-documenting, and easier to configure.
