ATX Amigas
The Amiga 2000 E-ATX
At the end of July the developer 'jasonsbeer' fixed revision 1.2 of his replica of the A2000 motherboard in E-ATX form factor, 'Amiga-2000-ATX', as production candidate. Now he has recommended all users who are going to build such a board to wait for he "expects to assemble and test the next revision (2.0) of the Amiga 2000 EATX board by the middle of November. The revision 2.0 board will have additional features that many will find attractive." Detailed changes:
- Supports both Agnus 8372A and Agnus 8375 (A500+/A600 variety) on the same board
- Added external floppy drive header
- Support for two real-time clock options
- Moved Zorro bus termination
- Cleaned up the schematics
Amiga 4000 ATX
A4000TX is an attempt by Hese to bring Amiga 4000 into any standard ATX chasing which is easy to buy today in every computer store. The A4000TX ATX motherboard is the first Amiga 4000 based motherboard in the ATX form factor (actually a hybrid ATX/EATX form factor). The motherboard is fully hand-routed like the A4000+ Alice motherboard was.
The project started back in 2018 and is still under development. So I want to share with you what he wrote on AmiBay in August 2018 regarding A4000TX.
