- Hints and Tips

- • A3000 bulging case − My early A3000 had, from the start, a standard
- Acorn monitor stand upon which was a AKF17 monitor. Of late, I found the
- upper case section, on the left hand side by the power supply, had
- started to bulge out from the bottom section. This was caused by the
- weight of the monitor supported by the Acorn stand only on the extreme
- edges of the case.

- In my job as IT Technician at school, I had noticed (having removed
- countless covers for various reasons) there have been two upgrades to
- the cases, and one of the upgrades had special strengthening and
- interlocking around this area, no doubt with this in mind. The latest,
- Mk 3 version is available as an Acorn spare part. The base of the new
- case requires a lot of work in removing the PCB and any upgrades, and
- the power supply design has changed making the changeover awkward.
- However the new case lid will fit onto the old base and this alone
- offers enough strength to cure the problem. K R Coton, Solihull.

- • Disabling POST test (and other useful ‘bits’) − One of our customers
- found that because the POST (Power On Self Test, or the software that
- makes the screen flash pretty colours at switch on and flashes the
- floppy light at you when things go wrong), had been partly disabled,
- meaning that his SCSI drive was not given sufficient time to get ready
- before the SCSI card demanded its attention. Some people may have
- disabled this after installing certain versions of the VIDC enhancer.
- The POST will always be reactivated by a delete-power on, but there is a
- more subtle way of switching it on or off. Byte 188 (&BC) of the CMOS
- RAM contains 8 bits which affect various miscellaneous configuration
- options.

- • Inkjet printers and paper quality − A number of items have appeared
- here and elsewhere on how to realise to the full the potential quality
- of printouts with ink-jet printers. At 300 dpi, one would think it ought
- to be indistinguishable from the output from a laser printer with the
- same resolution.
- 8.2
- Why is there a problem? All papers are made from fibres, matted
- together; thus, if you put a drop of liquid onto a piece of paper, the
- fluid will flow between these fibres, carrying with it any dye or
- colourant: hence the fuzzy edges of the output from inkjet printers with
- unsuitable papers. Coating the paper can eliminate the problem, but at a
- substantial cost. However, with careful design of the paper making
- process, it is possible to minimise (though not eliminate) this
- ‘bleeding’.

- I wrote to Hewlett Packard and asked for their recommendations They came
- up with two types of paper and their suppliers. I got some samples, and
- both were very good but, by a small margin, ‘Versoix Copy’ seemed to me
- the better (and cheaper). The other, ‘Reyjet’, is close behind and both
- are streets ahead of most ordinary photocopier paper. Neither is very
- expensive (about £3.00 per ream for Vesiox and £5.50 for Reyjet) but
- neither are very readily available. If you write to the distributors,
- they will send you samples and the name of your nearest stockist.

- • Irregular text frames in Publisher − In response to one of Keith
- Parker’s wish-it-did-that moans in the Comment Column (8.1 p31), I would
- suggest that whilst irregular text frames would be nice, the use of a
- regular frame “framed” by a couple of repelling irregular graphics
- frames (drag an empty drawfile into blank frames) does the job, with a
- little fiddling. John McCartney.
- 8.2
- • Large banners in Impression − To create a six foot long banner, or
- similar, using Impression, create a new master page, “Banner”, width
- 72“, depth 8”, Landscape, margins 0.5 with one column. Quit the master
- pages and alter the chapter of the document, selecting “Banner” as the
- master page. Change the font size to around 400 point and centre the
- text. Type the banner message. Print out on tractor fed continuous paper
- (sideways!). Vector offers some useful banners ready made, or you can
- use Impression’s Borders in ‘Alter Frame’, to enhance the finished
- article. Irene Quinn, Thetford, Norfolk.

- • Laser Direct on the Risc PC − If you are upgrading to a Risc PC and
- have an elderly Laser Direct card, it will not work if it is “Issue one”
- (the computer will not initialise after the board has been plugged into
- one of the expansion slots). This type can be quickly identified by the
- fact that it is the only version where there is a ribbon cable
- connecting the circuit board to the printer output socket. Computer
- Concepts will exchange this type of board for the latest version for
- £100. You will probably also need a copy of the most recent version
- (2.63) of the printer driver disc at £10. David Smith, Edinburgh.

- • More Sleuths on the case − If you are lucky enough to have lots of
- memory on your machine you can run two or more copies of Sleuth at the
- same time, so that if you are OCRing several pages of text, the rate of
- OCRing can be considerably increased. On a simple test run, two copies
- running saved 36% on the time taken and three copies saved nearly 50% on
- the time! It then occurred to me that using more than one copy might be
- infringing the software licence, but on checking with Risc Developments,
- I was assured that this was not the case. Philip Foster, Cambridge.

- • Turbo charging draft printing with a Deskjet printer − What I didn’t
- realise, until I tried it by accident, was that the ‘Draft’ button on
- the printer worked with graphic (e.g. output from Impression), as well
- as ‘straight’ printing. Thus, with your printer driver set to 150 dpi,
- and the ‘draft’ light on, you can produce readable copies for proof
- reading in virtually no time at all! Barry Humpidge.
- 8.2
- • Turbo Driver v4 and Dongles − If you are using CC’s Turbo Driver v4
- on a computer with a bi-directional parallel port, via a dongle, the
- status signals don’t get through. This includes signals, such as “paper
- out” and “printer offline” etc. If the driver software is looking for
- these signals you may find that printing is blocked. To bypass the
- problem call up the configuration dialogue box and configure to ignore
- status signals. Nick Harris, Norwich. A
