This is the first time I've seen this guy's page. It's all in German so I can't read it, but his work really does speak for itself. Amazing! He's a proper hacker isn't he.
It looks like he's redrawn the circuit for an A1000 in Eagle and made his own version of the motherboard as well? I loaded it up on my copy of Eagle and it looks great.
Fantastic.
AH.
Well it's a good thing I can translate, as far as my german goes, the following is written here.
Technical data:
68 040 @ 25-40MHz usable
68 060 @ 50MHz usable
64-128 MB SDRAM
4-1-1-1 burst to 50 MHz bus clock
Clock generation of logic-controlled PLL
Matched to the motherboard GBA1000
Map size: 147 mm x 98 mm
Connection via socket 68030
68 060 requires modified IDE-ROM
Conversion to HD floppy required (high)
Notes on Development
You will need a solid expertise to build and commissioning!
Without soldering experience with SMD components and deeper knowledge of the Amiga Hardware successful development will be difficult to overcome. As a basis for circuit design is the MC68040 Designer's Handbook a valuable help.
It requires a good quality of work tools and measuring technology!
For the development and deployment tools for programming of CPLD devices are needed. To search and elimination of errors in the minimal start-up an oscilloscope and a multimeter is required. For rapid fault isolation, access to a 68-channel logic analyzer advantage.
The project is operated on their own!
I give no support for this project. Neither for component procurement, nor to build and not to commissioning. It will not answer questions on this project of mine.
The whole point of this?
For those who want to have an A1000 with more power ...............
