ALGOR USB Controller (Pre-series card) ALGOR Logo
Amiga USB Controller for Zorro II

+++ Product is discontinued, please have a look at its successor: Deneb USB Controller. +++

ALGOR/ALGOR PRO is the successor of the well known HIGHWAY Zorro USB controller. After several months of development there is now a Zorro USB controller which is tailormade for Amiga Classic systems. For reaching this goal the most powerful non-PCI USB host controller which is available on the market now is being used.

As much customer requests in this new product as possible have been considered. By using the new controller chip most of the USB protocol handling could be managed completely in hardware which reduces system load in the Amiga multitasking system. This is especially important for systems with 'small' CPUs.

The request for higher data throughput could also be fulfilled. The ALGOR/ALGOR PRO internally operates completely in 32bit technology and it addresses with 32bit accesses on the Zorro II bus. As Amigas usually are operated with 32bit CPUs this implementation reaches data transfer rates on the USB side which are near to the theoretical maximum values. The ALGOR/ALGOR PRO compares by this design with comparable PCI DMA solutions, even if only 'small' CPUs like the 040 are used in the system.

ALGOR/ALGOR PRO is shipped with an OEM full license of the famous USB stack Poseidon by Chris Hodges. The Amiga Award Winner 2002 is completing the ALGOR/ALGOR PRO hardware with a field-tested software solution operating not only on Amiga Classic systems.

ALGOR/ALGOR PRO is offering next to its USB functionality several expansion possibilities. The HIGHWAY expansion port is also present on the ALGOR/ALGOR PRO and can be used to operate the NORWAY ethernet module.

Moreover, a 512 kB FlashROM (ALGOR PRO: 1024 kB) has been integrated on the ALGOR to transparently include the USB stack Poseidon right after a system cold powerup. This allows to boot an ALGOR/ALGOR PRO equipped system right off USB mass storage devices, to use USB mice and keyboards during Early Startup Menu and to include system patches like those from OS3.9.
