Dayna offers Ethernet for PowerBooks

Dayna Communications Inc of Salt Lake City, says that its DaynaPort SCSI/Link, a small external SCSI Ethernet adaptor, is targeted primarily at Macintosh PowerBook users. However, it is also designed for the Classic series and other Macintosh models that do not have an internal slot for an Ethernet card. The Ethernet adaptors connect all models of Macintosh computers to an Ethernet network using any type of cable system, and a variety of protocols are supported, including EtherTalk, TCP/IP, DECnet and OSI. DaynaPort adaptors work with a number of network operating systems including AppleShare, NetWare, TOPS and A/UX. The new adaptor has System 7 support, an easy installer and diagnostic software, and it measures 3 by 5.75 by 1.75. The product has two 25-pin SCSI connectors, is internally terminated via an on-off switch, and it comes with a 12 volt power supply. DaynaPort SCSI/Link has a BNC connector for thin Ethernet while the DaynaPort SCSI/Link-T has an RJ45 connector for 10Base-T twisted-pair wiring systems. Out in January 1992, the SCSI/Link will cost $400.

RasterOps says that its new ClearVue/PowerDisplay21 is a two-page monochrome monitor for the Apple PowerBook notebook series. The first in a new family of monitors that can be directly connected via a SCSI port, it is claimed to transform a notebook into a desktop system with high resolution and large screen display. Compatible with the PowerBook and any Macintosh model with a SCSI port, the 21 monitor has highly integrated electronics that are said to eliminate the need for a display board. With dual SCSI ports, the ClearVue/PD21 can interface simultaneously with both the Macintosh and external SCSI devices. It has a screen resolution of 1,152 x 870 pixels, or 77 dots per inch, as well as brightness and contrast controls. The ClearVue/PD21 can be used with the Apple PowerBook 100, 140, 170 or Mac models with a SCSI port, all Macintosh II models and Apple system software 6.03 or later. It will be available in December at $2,200.

CMS Enhancements disks for PowerBooks

CMS Enhancements Inc’s contribution to the

Apple jamboree consists of the LiteDrive PowerBook Series for the Macintosh notebooks. The LiteDrive models include a 40Mb, 80Mb and 100Mb internal hard disk and CMS says it is offering a 40Mb upgrade, the LDPB 40, since Apple will not be offering its own upgrade drives. The LDPB 40 costs $700 and will begin shipping next month. The LDPB 80, a fully compatible 2.5 80Mb drive upgrade for the PowerBook series, will also be out in November and costs $1,000. Both models have an average access time of 15mS and are said to provide higher throughput than Apple’s models. They include CMS SCSI Utilities 7.0 which provides hard partitioning with passwording, full System 7 compatibility, advanced caching and built-in drive evaluation tests. The 100Mb model will ship early next year. Also, CMS Enhancements has new Platinum Series drives for the Apple Quadra Series. The Series will include hard disk capacities from 200Mb to 1.6Gb, as well as 88Mb removable, digital audio tape and magneto-optical storage. The Quadra 900 tower configuration requires a new bracketing scheme, which CMS says it is currently developing. The company intends to ship a complete line of products for the Quadra 900 and the first offerings are the PQI 650 and PQI1000, but all of its current technologies, and a few new ones, will be out by the end of the year.
