Rancho Technology Inc of Rancho Cucamonga, California is ready with a low-cost SCSI adaptor for MS-DOS micros that starts at as little as $50 in quantity, reports Newsbytes, which says that the RT1000 host adaptors enable the micro to use standard SCSI devices such as hard disks, tape backup systems, and write-once optical drives, and there are models with and without floppy controllers; floppy models can control high- and low-density floppy drives, in both 3.5 and 5.25 form factors, as well as SCSI devices, from a single bus slot, and up to nine SCSI devices and four floppy drives can be supported by a single board; two models also include connectors for external devices, and prices for unit quantities range from $95 to $140.
