Impact Hard Cards
by Mike/Helvetica Sysop


The IMPACT Hard cards from Great valley Products Inc. USA

The first affordable, high performance, combination HardCard/SCSI peripheral controller for the Amiga 2000. Allows n internal hard disk to be installed without using one of those valuable drive bays, since it commes on the controller. This also allows an etraordinnarely easy instalation, since you only need to plug the card into your computer.

Here the list of Technical Specs :
- Combines ANSI X3T9.2 compatible SCSI controller and a 30 MB or 45 MB Hard Disk on a single A2000 expansion card. Of corse WITHOUT occupiing another peripheral bay.
- Available with 30 to 100 MB 3.5" hard disks. 19ms average access time on the 40-80MB drives.
- AUTOBOOT feature. Two ROM/EPROM sockets are provided for the Autoboot driver ROM/Eprom. This provides a 16-bit wide, zero waitstate, ROM memory with the utilisation of the Kick V1.3.
- Fully Aotoconfigures the SCSI hard disk Controller using the Amiga AUTOCONFIG protocol.
- External SCSI connector for conecting up to 6 external SCSI Drives.
- 16-bit wide Direct Memory Access (DMA) data transfer to onboard 16K disk buffer, provides high performance not affected by any other Amiga DMA activities (e.g. Blitter activity, overscan, etc.) This high performance design supports SCSI peripherals with a data transfer rate of up to 4MB/sec.
- Compatible with the new Amiga V1.3 fast file system. This speeds up all dive read/writes.
- Additional internal SCSI drive can be daisy-chained if required.
- Easy to install, high performance software driver, installation scripts and detailed instruction manual are included.
