ReAmiga 4091 SCSI-2 Host Controller
A brand new Zorro III SCSI-2 Controller for your Amiga
Facts:
- Fast SCSI-II (10MB/s max) controller for Amiga Computers
- One of only two Zorro-III SCSI controllers ever designed
- Full-length Zorro-III with DMA
- Designed for the Amiga 4000; works in the Amiga 3000
- Requires Super Buster 11
- Based on NCR 53C710 chip
- Autoboot ROM
- Reproduction based on an old board and PAL source code released as part of the Dave Haynie Archives.
- 80 components on the top; 147 components on the bottom
- Manual build time is about 7 hours per board - plus Debugging ;)
- The ReA4091 has been open sourced. Check out the A4091 GitHub project
- Modern Autoboot ROM with TD64 and NSD64 in development (open source)
Why?
Because we can, and …
● Classical Amiga hardware prices skyrocketed
● Inspired by folks like Paul Rezendes and John Hertell, and others!
● Dave Haynie Files!
● Create an accessible but compatible storage solution
● Open Source helps future generations learn about technology
● A tribute to the shoulders of the giants on which we stand today
