README
README.mdWhat is RaSCSI?
RaSCSI is a virtual SCSI device emulator that runs on a Raspberry Pi. It runs in userspace, and can emulate several SCSI devices at one time. There is a control interface to attach / detach drives during runtime, as well as insert and eject removable media. This project is aimed at users of vintage Macintosh and Atari computers and more (see compatibility list) from the 1980's and 1990's.

How do I contribute?
RaSCSI is using the Gitflow Workflow. A quick overview:
- The master branch should always reflect the contents of the last stable release
- The develop branch should contain the latest tested & approved updates. Pull requests should be used to merge changes into develop.
- The rest of the feature branches are for developing new features
- A tag will be created for each "release". The releases will be named . (for the first release of the month). Hot fixes, if necessary, will be released as ... For example, the first release in January 2021 will be release "21.01". If a hot-fix is needed for this release, the first hotfix will be "21.01.1".
Typically, releases will only be planned every few months.

Questions
How big is the Loopback tester PCB?
It measures 64.5 × 29.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Loopback tester use?
15 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Loopback tester KiCad files?
From the nucleogenic/RASCSI repository on GitHub, at the commit this page was made from: the board is hw/loopback_tester/loopback_tester.kicad_pcb and its schematic hw/ctrl_board_v1p5/ctrl_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Loopback tester design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
