Tape drive subsystem features integrated controller

Telex Computer Products' 8020-2X tape subsystem operates with IBM 360/370 and 4300 CPUs and is plug-compatible with the IBM 3803/3420 tape subsystem.

The drive features 6250-bpi, 1600-bpi, and 800-bpi operation. Tape speeds up to 125 ips are available.

The basic configuration is 22.5~ wide and consists of a cabinet housing two drives and the controller. Two drives can be added, giving users a I x 4 configuration. An optional feature permitting attachment of four more drives will be available later this year. Also under development is a switch that will allow the controller to be attached to two channels on one CPU or to separate CPUs.

The basic configuration is priced at $57,600. Additional drives are $18,900. Lease options are available.

Software program compares files, records differences

Ithaca InterSystems is offering a 1.0 version of its InterComp source compare utility software program. InterComp, which runs under CP/M on Z80-based machines, can be used to compare any two CP/M text files and report all differences, sending the output to diskette, console, or printer.

The comparison parameters of InterComp are user-defined and can be modified depending on the two files to be compared. The user can specify options to equate upper- and lowercase letters, specify similar lines to be paired, and define percentage of similarity desired.

InterComp can also be used to compare two object-code files, although no list of similarities and differences will be generated.

InterComp is available on standard 8-inch CP/M-compatible diskettes. The retail price is $295.
