Amiga 500 ATA hard disk interface

NIB image

Floppy-bootable HDD interface for Amiga 500. Achieves 600kB/s speed on unexpanded system. Works well with kickstart 1.3 and 2.0.

Should you have two HDD expansions mounted for same address space, you can invert master/slave select with a set of jumpers so that both can theoretically coexist.

This board is bundled with side expansion adapter, which converts hard-to-get edge connector into common pin header. For user convenience and safety of PC mainboards with ISA slots, future expansions will be developed with pin headers as their main connector.

NOTE: it is strongly recommended to wait for another revision of the board since Rev2 has some minor, but annoying bugs.

Release structure

Binary and gerber files are only packaged in releases. For gerbers see board/gerber directory. For device/software binaries see software/bin and device/bin directories.
