# About
2021-05-04 18:47:44 +00:00
*Blue-GS* is the internal hard drive your Apple IIgs and //e always *craved*.
2021-05-04 17:50:12 +00:00
Using the [BlueSCSI](https://github.com/erichelgeson/BlueSCSI) SCSI drive emulator and your compatible SCSI card, you have a fully internal hard drive with accessible microSD slot while still keeping your DB-25 connector free for other peripherals.
