TERMS OF REFERENCE I The terms of reference of the advisory mission requested by the £| Government of Ur&guay were to discuss computer applications in the mineral M sector. During an initial briefing with the Director National Direction for Mining and Geology, (DINAMIGE) he stated that DINAMIGE is looking for advice I regarding a computer system for the organization. A series of meetings with staff of DINAMIGE discussed current requirements and experiences in the three £ áreas specified: Administration Office; Mining Administration; and Scientific I Research. I 2. INTRODÜCTION I Industrial Minerals play a small role in the economy of Uruguay. There are numerous open pit and some underground operations. Recently the I potential for non-industrial minerals (gold and lead etc.) has been I recognised, for example, there is currently a three-year Federal Germán technical co-operation programme to establish a geophysics section and which I is providing equipment, training and fellowships. It is understood that I there have also been other bi-lateral programmes of assistance to DINAMIGE. I I I I I I I - 2 - I The three principal áreas of computer application requirements I are: 1) Administration Office 2) Mining Administration I 3) Scientific Research, including geochemistry, geophysics and geology. There is a variety of equipment and systems in use and it is clear • that it is time1y to consider standardización. l Office and Mines Administration information are currently being processed on a DIABLO 3200. This is an oíd computer with 64k, 5Mb hard disk l and with 5Mb removable disks. There is a problem with the printer which is i causing considerable loss of productivity (several hours to complete a few minute print out), but the company servicing the system has gone out af l business, and there is no longer any local service ñor support. The probable problem with the printer appears to be that the print-head needs to be l replaced. l _ Until recently the monthly maintenance charges were US$800 per • month. There is currently an attempt to obtain an altérnate maintenance I facility. This is only a short-term solution to the problem and it is recommended that action be taken to reduce DINAMIGE's reliance on this I technically obsolete system. It is noted that there is no back-up for this l system, and valuable data which are in regular use are stored on it . i I I I - 3 - I The payroll is currently being contracted out to a local firm using some IBM equipment. This is usually the best method of handling I payroll since it is the one área of applications that causes the most number I of complaints from staff if there are errors or if there are any delays for any reason. It is suggested that this continué, however, it is possible to I do the work internally if there are other overriding considerations. The other administrative requirements lie in the áreas of • inventory and expense reporting (currently both on the Diablo). There is a need for an accounting system, but this has not yet been successfully M implemented on the Diablo. Other needs lie in the control of supplies, and • payables. The Diablo is also used for control of mining administrative procedures. Normally the computer generates about three hours per day of • printout, on a five day week schedule. l The administration systems including payroll, accounting and i inventory control are standard applications in most industries. The transaction volume is not excessive, and microcomputer software is • extensively available. It is understood that a local consultant is looking at this for DINAMIGE, and if this were not the case a local management B consultant would be recommended to look at the flow of information and make • reconrmendations in this área. The source of such advice is usually fron one of the major accounting firms. l l I I I The terms of reference for such a consultant should include a review of current office and computer procedures relating to administration | and accounting activities and recommendations with special reference to low tm cost high capacity microcomputers and existing software (where possible). The equipment specification should be for a widely available and generally • supported unit (or its compatibles) so that the problems encountered with specialized units and only a small market share are avoided. It is important | to find out Che level of documentation, since the quality of documentation is wm crucial, especially for software. The documentation should include system specifications, programme specifications, programme listings, and a detailed • description of the options and user manuals with pertinent examples. The documentation is so important that it should be studied carefully. i • The training and support included in the purchase price should be established. The purchase terms should be clarified. Usually the software I is not for sale, only the right to its use may be purchased. The purchaser must ascertain whether the following support is provided: • a) installation cost, • b) training costs c) future improvements • d) warranty e) maintenance contract i i I I • The geophysics división has an IBM-XT compatible computer (VÍCTOR) • with 384Kb, a 20Mb hard disk, and an EPSON-LQ1500 printer. Without being critical, the system would be improved with additional memory to 640k and a • small line plotter. It runs under under MS-DOS 2.1 and was provided under a three-year Federal Germán technical co-operation programme to establish a • geophysics section and which is providing equipment, training and • fellowships. Within the equipment component some software to process ground geophical data was provided (from the Germán Geological Survey), including I MAG, GRAVTTY, VLF, VLF-R, IP (gradient), IP (diapole), EM and SON (Shclumberger). The manuals in Germán has been translated into Spanish, and • the programmes are menu-driven. The software is being used by the Uruguayan • geophysicists. • A brief meeting was held with the Chief Technical Adviser of the Germán Technical Assistance Programme and his national counterpartsv . and it • was explained that a proposal to fly the whole country with an airborne I geophysical survey was being prepared. The preliminary cost estímate of this survey is US$5 mi11ion, and sources of finaneing are being sought. It was • explained that UN/DTCD is not a funding ageney, and the UNDP programme offLcer _ explained that the IPF for Urfcguay is relatively small (US$1.1 million/year), * but that UN/DTCD did have extensive experience with national airborne I geophysical surveys in developing countries and it was mentioned that there is a Technical Adviser in Geophysics based at UN Headquarters, and that his advice and experience relating to the proposed airborne survey could be very useful to the Government. I I I • The geochemical división is currently using the Treasury m main-frame computer. There are three IBM-3278 termináis plus a printer connected by a modem and land line to che host facility. The software in use • was provided in a French technical co-operation programme and modified to run on the government computer. The plotter output is first obtained on magnetic I tape some distance from DINAMIGE and then brought to the geochemistry office • where there is a BENSON 1221 muíti-pen plotter with a BENSON 400 tape drive and plotter controller. There is also a large digitizer (BENSON 6201 with I modem) but this is not connected to any other equipment. It is used to provide coordinates from maps, which are then entered manually into the main-frame computer. Although the system is working well enough, it may be i useful to consider some rationalization of work. I The acquisition, storage and processing of geological, geochemical and geophysical data during exploration are important áreas. There %& • extensive software available for these applications on microcomputers. The • digitizer could be linked for direct data entry to reduce the scope for errors. The approach taken in the geophysics work is an extremely • appropriate and sensible one, and this should serve as an example for other applications. It should also be noted that the more powerful 80286-based ™ microcomputers are now widely available with one or two megabytes of main • memory, a mathematíes co-processor, and a 70Mb hard disk main storage unit, and also a second 30Mb half-height hard disk may also be installed in the • uni t. I I I I I - 7 - I 3. STANDARIZED GEOLOGICAL CODES I Interest was expressed in standardized code for geological rock types and mineralization etc. It is recommended that DINAMIGE consider the I FRANKLIN system of coding, a modificación of which is attached as.Annex 2. This is a system of alphanumeric representation in which the letters are removed in a predetertnined sequence to arrive at two, three, four or more I letter codes., I 4. CONCLUSIONS AND RECOMMENDATIONS I There appears to be very little need to establish a central system • from the brief examination of the needs at DINAMIGE.

  • Resident Programs Chapter 18
    Resident Programs Chapter 18 Most MS-DOS applications are transient. They load into memory, execute, terminate, and DOS uses the memory allocated to the application for the next program the user executes. Resident programs follow these same rules, except for the last. A resident program, upon termination, does not return all memory back to DOS. Instead, a portion of the program remains resident, ready to be reactivated by some other program at a future time. Resident programs, also known as terminate and stay resident programs or TSRs, provide a tiny amount of multitasking to an otherwise single tasking operating system. Until Microsoft Windows became popular, resident programs were the most popular way to allow multiple applications to coexist in memory at one time. Although Windows has diminished the need for TSRs for background processing, TSRs are still valuable for writing device drivers, antiviral tools, and program patches. This chapter will dis- cuss the issues you must deal with when writing resident programs. 18.1 DOS Memory Usage and TSRs When you first boot DOS, the memory layout will look something like the following: 0FFFFFh High Memory Area (HMA) and Upper Memory Blocks (UMB) Video, ROM, and Adapter memory space 0BFFFFh (640K) Memory available for application use Free Memory Pointer Interrupt vectors, BIOS variables, DOS variables, and 00000h lower memory portion of DOS. DOS Memory Map (no active application) DOS maintains a free memory pointer that points the the beginning of the block of free memory. When the user runs an application program, DOS loads this application starting at the address the free memory pointer contains.

  • Explorer's Guide to the HP 95
    In 1991, while experimenting with one of the very first HP 95 portable computers, this book came together. Today, more than fifteen years later, that HP 95 computer still works great, though it’s creaking and slowing down a bit and doesn’t have the battery Explorer’s Guide life it once had; I know the feeling. To The I would like to invite you to wander through this book, to see what an eleven-ounce computer could do, not all that long ago. Rumor has it that HP later released very nice palmtop computers with 100 HP 95 and 200 model numbers, even though this book knows nothing about them. I’ve simplified some illustrations for this online version, but text and page layout still look like 1991. On the left is something like the original book cover, complete with the old rabbit logo. One edition of this book was formatted with Microsoft Word for Windows 1.1. It was printed on an HP DeskJet 500 printer, which R. E. Harvey was a 300 d.p.i. B&W inkjet that scooted through about two pages per minute in best-quality mode, and cost more than $500. Body Palmtop PC Palmtop PC R text in this book is still in Bitstream Charter font, which was designed for low-resolution laser and inkjet printing. There are 112 pages and around 53,000 words. The peculiar page count begins with this title page. Maybe I was trying to make it sound like a lot of pages, while actually keeping the page count down; maybe it was something else.
