PC-l86 Parallel l/O Port About this Upgrade The Parallel l/O port and user port The Parallel l/O port is a socket for connecting a parallel printer. lt is attached to a card that you slot into your PC-186. We refer to the card as the Parallel l/O card. fhe user porf is an optional socket on the end of a ribbon cable that connects to the card. The user port is similar to the port on a BBC micro. You can use this port for sending data to a printer or receiving data (i.e. itis bi-directionafl. How to use this booklet This booklet shows you how to: 1. Fit a Parallel l/O card and user port to your PC-186, if not already fitted. 2. Use the Parallel llO port and user port for basic printing tasks. lf you are fitting the l/O card yourself, first read the appropriate chapter for your computer. Your PC has either an 84-key or a 1A2-key keyboard, and the internal layout of each type is different. lf you are unsure what you have, the 102-key keyboard has the function (F) keys along the top. When fitting is complete, install the software as shown. Read the appropriate chapter for standalone or networked computers. (This is where you start if the l/O card was supplied already fitted.) Chapter 5 then tells you how to use the parallel printer port. Finally, there are specialist chapters for experienced users and a troubleshooting chapter to help if problems occur. ll you have olher optional cards in your PC, particularly a data communications (DCC) card, GPIB card, or cartridge tape controller card, read the information given in chapler 6, "Conliguring the Parallel l/O Port'. PC-l86 Parallel l/O Port Chapter 1 Fitting the Parallel l/O Card to a PC-186 with a 102-key Keyboard Before you begin Read chapter 10 of your Owners Handbook for details of dismantling the computer and inserting cards. We reler to the handbook in the following instructions.

To order a new bus cable contact lhe RM Sales Desk, Preparing your computer Use the HARDDISK command to secure (park)the heads of the winchester disk, if fitted. Remove the cover of the computer. Find the bus cable: this is the ribbon cable that connects the main board to the disk controller card. This bus cable attaches to the main board and connects to the edge of the disk controller card and any optional card(s). lf you are replacing the old bus cable, disconect the old one from the option board and main board and remove it. PC-l86 Parallel l/O Port lf you have a diskless network station (TN), this does not apply but you should connect the new bus cable to the mainboard before inserting your new option card. Fitting the card There are three horizontal slots for cards to slide into. The top slot may contain the disk controller card and you may have optional cards fitted in other slots. You need at least one free slot to fit the card and user port. You normally use the middle slot to fit the card, and this corresponds to the top opening on the rear panel. o lf you have two slots free, follow the instructions "Two slots available", below. r lf you have only a single slot free, follow the instructions "Single slot only". r lf you have no free slots, you must remove at least one of the optional cards and then read the appropriate set of instructions mentioned above o lf you want to use the user port of the l/O card as well as the parallel printer poft, connect the 20-way ribbon cable provided with this package to the socket on the l/O card as in the diagram below.

  • The Flashback Project: Rescuing Disk-Based Content from the 1980S to the Current Day
    IDCC16 | Research Paper The Flashback Project: rescuing disk-based content from the 1980s to the current day. Maureen Pennock Peter May Michael Day The British Library The British Library The British Library Kevin Davies Simon Whibley The British Library The British Library Akiko Kimura Edith Halvarsson The British Library The British Library Abstract This paper introduces the British Library’s Flashback project, a proof-of-concept that explored the practical challenges of preserving digital content stored on physical media (magnetic and optical disks) using a sample of content from hybrid collection items dating from between 1980 and 2010. It describes some of the activities undertaken by the project, including: the initial collection profiling and sampling of content, the extraction of content from the disks, and the project team’s experiments with identifying and applying preservation approaches to the content, which included both emulation and migration. It concludes with some general observations on the approaches taken and looks forward to the second phase of the project. Introduction The British Library is the UK’s national deposit centre for published content. Its collections are vast and comprise everything from books and journals, to maps, newspapers, electoral registers, and patent specifications, in both hard-copy and electronic form. It also contains one of the largest collections of recorded sound in the world. The Library’s digital preservation team has been working on strategies to preserve the digital elements of the collections since around 2005. Recently, attention has turned to digital content acquired before this date, content that is typically still stored on its acquisition media, with examples in the Library’s collections dating back to the 1980s.

DESCRIPTORS *Computer Assisted Instruction; Computer Networks; Computer Software Selection; Computer System Design; *Curriculum Development; Educational Needs; Foreign Countries; *Instructional Design; *Interdisciplinary Approach; Microcomputers; Secondary Education; *Urban Education IDENTIFIERS British National Curriculum; *United Kingdom ABSTRACT The program for City Technical Colleges (CTCs) draws on ideas and resources from government, private industry, and education to focus on the educational needs of inner city and urban children. Mathematics, science, and technology are at the center of the CTCs' mission, in a context which includes economic awareness and a commitment to enterprise and wealth creation. This discussion addresses the question of computer provision in the context of the need for children to learn skills in the technologies now central to their existence, and their need for sufficient access to relevant equipment through their learning experiences at school if they are to develop such skills. This paper presents a rationale for providing information technology (IT); a discussion of how subject areas in the National Curriculum, ranging from science to dance, can be enhanced by its use; suggestions for staffing and administering IT programs; and a discussion of issues concerned with system purchase, support, and maintenance.
