This image was on a CD-ROM which was placed in a time capsule in December 1997, just before the Ballarat School of Mines merged with the University of Ballarat (now Federation University Australia). The time capsule should have been opened in 2020, the 150th anniversary of the establishment of the Ballarat School of Mines, but was postponed due to successive lockdowns during the Covid19 pandemic. The time capsule was opened in 2022.The Ballarat School of Mines Dot Matrix Printer used to print internal and external assessment sheets from the student record system SMBSMART for the student records department. It was located in the SMB Brewery Building.ballarat school of mines, time capsule, information technology, computers, brewery building, dot matrix printer

Copy of an article by Neville Gower, published in "Somersault", the magazine of the Signalling Record Society of Victoria, May 1988. Describes location of loops in horse drawn era compared to those of the ESCo area 1905 to 1934, with reference to changes made to ESCo Loops by SECV upon rehabilitation of the system, based upon changes on BTM's collection of staffs. Published in p54, 55, 56 and 60 of Somersault, May 1988. Copy supplied by Graeme Reynolds, printed with a dot matrix printer. Page 56 and cover page supplied by Warren Doubleday (2/1999). Was a follow up article or item by Peter Barry in the July 1988 issue and an article on Bendigo during 1989. (Information provided by David Langley editor at the time - 1/1999).

The Micro-Professor I Plus (MPF-IP) was a low cost, versatile microcomputer system featuring sophisticated software and hardware capabilities. (MPF-IP) boasted a display panel with the ability to display 20 characters using 16-segment fonts. All 64 standard ASCII characters could be displayed. The operation of the MPF-IP was controlled by an 8k monitor program which resides in the Read Only Memory (ROM). The monitor, aided by 4k Random Access Memory (RAM), enabled the user to enter a comprehensive set of single keystroke commands, making it easier for the user to use the CPU, memory and I/0 devices. This allowed the user to concentrate of microprocessor software development and application design. The system allowed printing at 48 lines per minute, and the ability to permanently record the commands, data, programs, status and other messaged. Each character printed by the printer is in a 5 by 7 dot matrix. Although the prime purpose of the programming was for machine language object code formed as hexadecimal numbers, the Micro-Professor has an embedded Tiny Basic interpreter for which formation of some of the alpha characters using a standard 7 segment display was ingenious. The program memory consisted of non volatile 2 kilobytes electrically programmable ROM whilst the Random Access Memory came with 2 kilobytes of static RAM but could be upgraded to 4 kilobytes by insertion of another chip. The entire memory space of 64 kilobytes was accessible by way of the terminals on the left hand side of the board. Engineering and Science students from the Ballarat School of Mines and the Ballarat College of Advanced Education used a class set (as they were relatively inexpensive at approx. $100 each) during the mid to late 1980s. Student were encouraged to borrow the Micro-Professors in order to assist in learning how to use them. Only one was ever not returned on time. When pressed to return the device the student confessed that his dog had chewed the plastic case. This is still in our collection complete with bite marks! The Micro-Professor used a Zilog Z80 microprocessor. This was the most powerful of the 8 bit microprocessors at the time. Zilog was derived from the Intel 8080 microprocessor. The Z80 had 158 instructions of which the Intel 78 instructions were a subset. The Intel processor continued on through development in the IBM computers as 8086, 80286, 80386, 80486 and later the pentiums. Zilog lost most of its market share when it developed the 16 bit Z8000 microprocessor. Although the microprocessor was excellent, the lack of peripherals caused users to abandon Zilog products.

The HP-85A was Hewlett Packard's first Series 80 microcomputer, introduced about 1979. It had a keyboard, a dual alpha/graphics monochrome display, a bidrectional alphanumerics and graphics printer, and mass storage tape drive all integrated into a marvelously designed and compact case. It's operating system was seemlessly integrated with a powerful BASIC programming language that included intuitive graphics and input/output capabilities. The HP-85A was also wonderfully expandable through four ports on the back of the case for adding plug in ROMS and modules. Specifications CRT DISPLAY Size: 12.7 cm (5 in.) diagonal Alphanumeric capacity: 16 lines x 32 characters Graphics capacity: 192 x 256 dots Scrolling capacity: 64 lines Character set: 256 characters; set of 128 + same set underscored Character font: 5 x 7 matrix Intensity: adjustable Cursor: underscore BASIC LANGUAGE AND OPERATING SYSTEM Standard ROM - 32K bytes Maximum add-on ROM - 48K bytes CRT memory RAM - 8K bytes USER READ/ WRITE MEMORY Standard - 16K bytes Maximum - 32K bytes TOTAL MEMORY Standard - 56K bytes Maximum - 120K bytes (Information from http://www.ebbsoft.com/hp/85a.htm)Personal computercomputers, monitor

Photo shows a lady and a gent looking at the output of an accounting machine computer printer. The type of paper used had holes on the side for printer control and used a dot matrix output, with perforations so each sheet could be detached. This type of equipment was installed by the MMTB during 1957 - see 1957 Annual report page 33 for the printer in use at head office along with other machines and item 4509 for other photographs of the equipment of the time. Second photo shows a punch card operator at the punch card machine which were later used in accounting computations.Yields information about the type of computer machines used by the MMTB during the mid 1950s.
