North Haugh, St Andrews KY16 9SX, Scotland, Telephone 76161 (3) COMPUTER USERS COMMITTEE

The Committee met on 11th March. With reference to the minutes of the previous meeting, a requirement was expressed for extra Macintosh microcomputers to improve the access to the Laserwriter.

However, in view of the uncertain financial position and the need for a University-wide view to be taken, word-processing software for the Zenith workstations would be investigated with the requirement to improve access to the Laserwriter in mind. Arrangements had already been made to accommodate users wishing to print on the Laserwriter files previously prepared on disk.

Local Area Network performance: Difficulties were reported by the Mathematics Institute and the Economics Department in their connection to the VAK. systems via the Cambridge Ring - delays, loss of results and abrupt disconnection and the appearance of spurious characters. It was explained that the CAMTEC software was not reliable and collective pressure was being exerted on the company with other user sites - recent high traffic volume aggravated the problem.

Following the failure of the MACE project, the current method of connection to the VAX was an interim one, and a different product (DEXPAND) was being tried, but had run into difficulties: it should give greater throughput and by-pass the Ring-X25 gateway - the least reliable component. The problem of spurious characters had been reported by other sites, but a cure had not yet been found.

The relationship with CAMTEC was unsatisfactory - they now marketed other products (such as Ethernet) to the detriment of their support for Cambridge Ring technology. The reported problem of "sticky" cursor movement during screen editing had resulted in long-awaited "patch" from CAMTEC, which did not work. The Director suggested that comments needed to be passed on to those bodies who were recommending the company I s products: it was hoped to arrange soon a meeting with the Director of the Network Executive of the JNT; an approach to the Computer Board for further network funds was being held up until the Ring situation became clearer.

Removal of non-NRS names from the network authorisation scheme: The Name Registration Scheme had been set up to ensure that a unified set of mnemonics was used by all JANET sites in order to refer to other sites. These NRS names, which replaced the local mnemonics, were now in the network authorisation file on both the VAX systems, and the removal of the old names had been announced, although a request for their retention had been received. Because of the advantages of using the universal and up-to-date NRS names and the disadvantage of the old mnemonics gradually becoming invalid as site addresses changed, it was decided to keep to the proposed change-over, as announced.

Student Works tat ions project: The choice of Zenith IBM-compatible microcomputers had already been announced, and an order for fifteen for the North St site had been placed .. delivery was due at the end of March. Some of the building wiring remained to be done and some software items were yet to be selected and purchased.

Individuals planning to run classes on the workstations could try them out from mid-May; it was hoped to have the local area network

The choice of agreed to proceed with its disposal. such equipment is inevitably a compromise. Various factor.s had to be considered in the choice of workstation - hardware quality, available software, cost, eas. of use, after-sales support, etc. In addition, it was decided to look at equipment with assured delivery and to ignore rumours of 'future' products. Following the Computer Users Committee meeting, the Computer Board announced that the Minor Facilities Grant for 1986/87 would be the The University now has a discount agreement negotiated by the Inter same as for the previous session.

TEN YEARS AGO

In the Newsletter for April 1977, an announcement was made about forthcoming upgrades to the IBM 360/44: the 2311 demountable-disk drives (7. 2Mb per ten-surface pack!) were to be replaced with 2314 drives having four times the capacity; the magnetic tape drives were to be replaced by drives incorporating 1600 bpi density as well as 800 bpi, and the printer would be replaced by a model running at nearly twice the speed (970 lpm).

Two well-known software products were being updated: GLIM went from Release 2A to Release 2B, and the NAG library was being replaced by the Mark V version. Another popular program, the GFORTRAN compiler, had thrown up a minor error in its implementation of LOGICAL*l variables unfortunately, this compiler was a non-standard one obtained from another university, with no possibility of local support as the source code was unobtainable.

The Laboratory and the Computer Committee were reviewing the policies on operating systems on the 360/44 and the off-loading of work to other university computers. In the same issue, the new DECsystem-lO at Dundee was announced: access to this had been negotiated, and was available from St Andrews on a Texas Instruments terminal with hard-copy output, via a GPO (BT) dial-Up line at 30 characters per second ..•
