"This card provides a common OEM development of individual computers and on behalf of, E3B amigakit.com (Mathew Leaman) dar. The Zorro III E3B know-how comes from, as the circuit board layout and the extremely slim-SDRAM controller, the know-how comes from individual computers on SDRAM and the manufacturing experience for a high-quality production of the cards at the same time an attractive retail price.
The card (project name "ZorRAM") will be available exclusively at amigakit.
The technical data in brief:
- compact Zorro III card (130x55 mm ^ 2)
- Four-layer PCB
- 128MB or 256MB of fast SDRAM (soldered)
- real 32bit design
- Full support for Autoconfig
- RAM is automatically integrated into the system
- RAM can be "manually" integrated addme /
- low power design
- slender, but faster FPGA for interfacing to Zorro III
- no Zorro II support (makes no sense at 8MB address space) "
