MDS-D REVISION 2 25010 INTRODUCTION The North Star Micro-Disk System (MDS-A-O) is a complete floppy disk system for use with 5-100 bus computers. The system .• includes the disk controller board, one floppy disk drive, power regulation, cables, software and documentation. The software is provided on diskette and includes the North Star Disk Operating System, BASIC Language System, Monitor, and various utility programs. The system is capable of controlling up to four disk drives. Each disk drive can record 179,200 bytes of information on a diskette, thus allowing up to 716,800 bytes of on-line disk storage. Addition disk drives, AC power supplies, and cabinets are available as options If you have purchased the MDS-A-D as a kit, then first skim the entire manual. Be sure to carefully read the Assembly Information section before beginning assembly. If you have purchased the MDS-A-D in assembled form, you may skip the A Assembly section. ., CAUTIONS .- 1. Correct this document from the errata before doing anything else. 2. Do NOT insert or remove the MDS controller from the computer while the power is turned on. -

Previously reviewed in this series have been the Texas Instruments 771, the Pertec PCC 2000, and the North Star Horizon. And still to come are eight more systems in the under- sls,ooo price range. The goal of this series is to provide users with compara tive information on a number of small systems, information which will be valuable in selecting from among the many alternatives available. We have found that many published comparisons of computing systems report only the technical specifications supplied by manufacturers, and such information is difficult to interpret and seldom comparable across different computers. -

The changes began with the introduction of digital system design methods, and increased with the subsequent introduction of microprocessors as widely-used programmable components, for which software design expertise was an essential part of their utilisation. Keywords: Microprocessor, electrical engineering students, curriculum 1 The Higher-Education Background in UK In the 1960s and early 1970s teachers in UK universities had considerable freedom to interpret the syllabuses of courses which they taught. -

BASIC Overview • Constants. BASIC programs are made up of statements that contain keywords, variables, operators, and constants • Numeric constants (Floating point and Integer) - Each BASIC version handles numeric constants differently. • Character String constants - signaled by a quote (") • Variables - "names" that may take on different values during a problem. - vintage versions of BASIC required variables to start with a letter. Matricies (1966 Dartmouth BASIC) • A matrix is simply a rectangular array of numbers • An array is a set of numbers arranged in rows and columns • A matrix may also consist of a single row or a single column, also called “row vectors” (lists) and “column vectors”. 10 REM MATRICIES USING DARTMOUTH BASIC 20 DIM S(2,2) 30 MAT READ S ... 240 DATA 30, 50 245 DATA 40, 25 250 FOR K=1 TO 2 260 PRINT S(K,1) 270 NEXT K RUN [What would be the output??] Matricies (Digital PDP 11 BASIC) 10 DIM A(2,3) 20 FOR I=0 TO 2 30 FOR J=0 TO 3: LET A(I,J) = 0 40 NEXT J 50 NEXT I 60 FOR I = 0 TO 2: LET A(I,0) = I 70 FOR J = 0 TO 3: LET A(0,J) = J 80 PRINT A(I,J); 90 NEXT J 100 PRINT 110 NEXT I 120 END RUN 0 1 2 3 1 0 0 0 2 0 0 0 STOP AT LINE 120 READY What’s different?

This device. including its attending soft ware, very nicely matches the needs of a small (less than $4000) microcomputer system. The discussion is divided into several progressive sections. The foHowingsection deals with hardware aspects of the North Star disk system, along with some spot comparisons with other products. The next section provides a user-oriented description of North Star's very adequate disk operating system software. -
