NZ Amiga Users Group (Wgtn), c/- Tony Wills, 156-C Queens Drive, Lyall Bay, Wellington 3. Ph (04)877-258 (home) (04)850-559x743 (work) ~Editorial :` First I must thank all those who contributed something to the newsdisk, it is all much appreciated. But remember there will be another newsdisk next month so don't stop now! If I haven't replied to your letters over the last couple of weeks it is because I have been having disk drive problems. Anything written on tracks 70 to 79 (side 1) of my external drive couldn't be read reliably by my internal drive, although the internal drive seemed to be able to read everyone else's disks. Which appeared to indicate a problem on the external drive. But to compound things the internal drive sometimes had problems formatting disks - so perhaps the problem was the internal drive, or was it both?. Well after putting up with this problem for a month or so, because I couldn't bare to lose my Amiga for any length of time as I am using it continually (and I don't think my constitution could stand the withdrawal symptoms), I bought some disk drive cleaning disks (a little under $60 for 10 retail, more like $40 wholesale) and ran them through both drives. On testing with a copy of our last newsdisk I still couldn't read in the DireStraits digitised sound file (it's a few hundred kbytes long and spans tracks 70-79) on the internal drive but it loaded perfectly from the external drive (as it always has). So I dragged the machine off to the local Commodore service agent, and left it and a (different) copy of the newsdisk with him, to work out what was wrong. In somehow keeping with the spirit of Parkinsons Law (Anything that can go wrong will happen while you're trying to demonstrate something - A special case of Murphys Law) the machine behaved without fault! Upon retrieving the machine I find it is reading disks OK, but there is only one particular copy of the Newsdisk that is only readable by one drive, and it is unable to format disks (the latter facet of things I forgot to mention to the service agent.) I know a number of members have had disk/diskdrive problems, and I was told that later machines have different drives - can anyone confirm this? ~News :` I have scoured the US Bulletin Board systems, that I've access to, for info about the next Amiga, but I can find no hard, or particulary definitive info on what is coming and when - it appears that we may have to wait until the end of the year before we see any significant advances on the Amiga front. Thats not to say there won't be other models released in the interim. Still haven't recieved the official version of Workbench 1.2 and documentation updates, looks like it will be $NZ60 (ie we now multiply US prices by 4 to get the NZ equivalent!) The Christchurch group is reported to be building external disk drives for $300 each (I dive for cover to avoid the stampede). But I haven't had any direct contact on this matter, so don't know whether this includes a case and perhaps power supply, and how compatible they are. A Wellington member is looking at designing a circuit board for the expansion RAM detailed in a previous newsdisk. I expect this may take a little time but we live in hope! If you are interested let us know - the more interest, the more worthwhile the effort. A dealer is considering importing 2MByte RAM boards, these boards are fully populated (and actually contain 2MB, unlike some other boards that only contain 1.5MB, and bring your system upto 2MB total), they also pass through the expansion buss so further peripherals can be added on. The expected cost is $1400 including GST (if you think of it as $700 per Meg it sounds quite good) I don't know of anyone who has tried their own NTSC to PAL upgrade, (as per last newsdisk), if you have, please let me know the outcome. It may be wise to ask your local service agent to do the mod.s after consulting with the Auckland Commodore service experts. (I trust they will not charge $300 to cut one track on the mother board!) 1 Megabyte 100nS RAM chips now selling for $US36, 256K chips for $US2.85 - cheap RAM boards should be getting closer! ~Old News :` Musicraft (music composition program from Commodore) has been released as Sonix and will be published by Aegis. It has reportedly been enhanced, and now supports sampled sound instruments, and MIDI interfaces, and can use IFF music files allowing interchange with other music programs. Draw Plus from Aegis is now available, extending their drawing package to a full CAD system, not copy protected, DOS 1.2 compatible. ~Letters to the Editor :` Dear Tony, ... As for PAL conversions, I've recently heard that Ashby Computer Centre in Auckland has taken delivery of the upgrade kits - but as of yet, I am still unaware of the price. Ashby also seem to have taken delivery of memory expansion units - no doubt more such add-ons will be popping up around the country over the next few months. In response to your plea for more user input for the news letter, here are several simple tips concerning the startup-sequence gleaned, from the pages of AmigaWorld, that I have found particularly useful - and are geared more towards those, who like me, are still only in the early stages of coming to grips with their new "toy" and are still too broke to splash out on the AmigaDOS Manual. Using ED to modify the startup-sequence, it can be modified so that you no longer have to use preferences to enter the correct date and time on startup, and also to open a small CLI window on the opening Workbench screen - saving the hassle of opening up the System draw. The easiest way to provide these tips is simply to give a complete listing of my own startup-sequence. echo "Workbench disk. Release 1.1" echo " " echo "Default Date:" date echo " " echo "Set the Date and Time!" echo " DD-MMM-YY HH:MM" echo " " failat 21 date > nil: ? if fail echo " " echo "Please try again!" echo "Use SPACE to separate Date and Time." echo " " date > nil: ? endif date date to sys:s/Last-Startup-Date echo " " LoadWb newcli con:540/150/100/50/cli endcli > nil: Note that the sequence saves the current Date and Time to a file in the S subdirectory called "Last-Startup-Date" - and as always, try this out on a backup-copy of Workbench first. The sequence " > nil: " serves to suppress requesters and system messages, while " con:540/150/100/50/cli " opens up the CLI window, with the numbers determining its size and position. The beauty of this method is that once you have input a date such as "10-Feb-87 12:00", upon booting up of the system the following day, you have only to input "Wednesday 13:00" for the system to readjust itself. Although much of this is old ground, it may help some of those still progressing slowly through the system. You were right, complaining about lack of material DOES seem to work!!! Also, some words of advice for other Amiga Users; when you see those Reader Service cards in the back of the overseas magazines, don't just ignore them, FILL THEM OUT!!! While it's true that only a minority of the companies concerned will ever respond, those that do tend to provide some very interesting product information, and this serves to reinforce the confidence of the user worried that the Amiga has lost some of its initial momentum overseas after its first great splash. Pity about the unavailability of these products in New Zealand though, I always like to have a bit of a play round on the equipment before I buy. --- Andrew Mercer ~--------------------------------` Dear Tony, It's jolly to hear you're now getting a bit of stuff from other Amylubbers - it'll save you making up anymore letters from imaginary peoples. Marauderingly yours BLUEBOTTLE (ALL letters have been from members as real as YOU or me! -ed) ~----------------------------------` ... something novel : The signatures of the people who designed the Amiga are formed on the top cover (of the Amiga), on the inside John Veldthuis (Mania) (Worth a look if you get the chance, {I think the Mac may have started this tradition} but Commodore may have something to say about your warranty if you pop the lid off without knowing what you're doing -ed) ~----------------------------------` Dear Tony, I feel a bit embarrassed at your call for material for the Amiga Group, mainly because I have had a lot of good help from others, but the things I have been developing myself have never quite got to a finished state. However here are a few items: ~KILL!!!` ------ There is a great need for a KILL TASK command ------ I can't understand why Commodore/MetaComco didn't build a command like this into the operating system at the start. Don't they ever have programs that lock up the system??? It takes a long time to clear a queue of 50 000 "printer trouble" flags for instance if you are using a program that doesn't provide for you to abort a long print output if it has gone sour. When you have only one drive (and you ARE entitled to) then you need to have some kind of RAMdisk setup, and perpetual rebooting to recover from program weaknesses does nothing to enhance Amiga's image - especially as this problem always crops up when you're trying to impress some snooty VAX-Hacks or something. But it would really do a great deal to make life more comfortable on the system. (It may be that the system does not keep track of which programs have been allocated which resources - and hence it wouldn't know what to release after 'killing' a task -ed) ~CONTOUR` I have written an AmigaBASIC program around a contour plotting routine from BYTE, Nov 1983. It's quite reasonable now if you want contour plots, but has one residual bug which I have for the moment given up trying to kill - that is that it doesn't always synchronise the y-position of the contour with the y-scale. The problem is x-y symmetrical and the same method of handling the two dimensions is used, but there is a y-flip operation built into the BYTE routine and this has trapped me somehow. So until that is fixed I have (a) just added a runtime option for the user to vertically reposition the plot (b) deferred some tidying up. All the subroutines, for instance, should be made into isolated blocks and thus be more available as future program blocks. (I have fixed this problem, more or less, you hadn't handled the 'y-flip' ,you talk about, consistantly -ed) The listing is included here as CONTOUR1, with a CONTOUR.readme file and a short TESTCONTOUR file so that a demo can be run. (included on the newsdisk -ed) ~ED` I use ED quite a bit, it has many good features and some very irritating ones, and overall I don't find TEXTCRAFT or SCRIBBLE to be sufficiently better to want them a lot. One reason is that ED is just much easier accessible, another is that the methods used by all three for cutting and pasting and other "simple" operations are really pretty clumsy, and the "powerful enhancements" of the packages are useful mainly to get cleaner printout. So I often write text on ED (as now) and then transfer to say TEXTCRAFT for printing. This too is a pain. There are some things I would find MOST useful with ED: Command file control- For difficult reformatting jobs which may have to be done on more than one occasion, or repeated because you couldn't get it right the first try, wouldn't it be loverly to be able to say;- ED from" if not exists ram: makedir ram: endif copy df0:/#? to ram: echo "insert disk to write to" wait 10 sec - this gives you time to swap disks makedir df0: copy ram:/#? to df0: delete ram:/#? ram: echo "copy directory finished" ~Fragmented files:` One of the reasons for above is that if the files on a disk get fragmented, they load slowly. A good way to find out if your files are fragmented is with program FM (FileMapper) from FF disk 36. This is a great utility. But does anyone know if it can be made to trace through ALL files for you? -the equivalent of the "dir opt a" process? Yours hackfully, Harry Trethowen ~----------------------------------` Dear Tony, ... The Amiga is obviouly far too dependant on DF0: When mine gets hot it won't even recognize a kickstart disk. It is a pity there is not a switch on the machine to get it to boot off DF1:. I suppose that when I get a hard drive (No 2 priority on my hardware list) I will still have to Kickstart off DF0: How often are you supposed to clean 3.5" drives? I have had my Mac for nearly 2 years and I haven't had to clean it yet. On the other hand my machines with 5.25" drives have to be cleaned every 2 months or so. (If you are having disk drive problems, first get the heads cleaned -use a non abrasive cleaning disk. If the problem persists get the drives checked out by Commodore service agents - One hopes that the drives can stand up to New Zealands relatively mild ambient temperatures, and not overheat - ed) This letter was prepared on a Macintosh as there is as yet no WP for the Amiga that is as good as MacWrite. Yours sincerely, Ross Deeley (I can't be sure whether you're right as I haven't seen all the Wordprocessors that are advertised in the states, but certainly I couldn't faithfully reproduce your letter with Textcraft, for this newsletter. Perhaps Delux Print would be more appropriate. To some extent it appears that it has been conceded that the Mac is the Desktop Publishing king and so they are pushing the Amiga as a Desktop Video king. Until long persistance monitors are standard, so you can use 400 interlaced lines {without pain!}, I think the Amiga may stay behind in this field. -ed) ~------------------------------------` Is there anyway you can use Musicraft (Pre-release) scores in AmigaBASIC? Jonathan Clarke (Napier) (Can anyone help? -ed) ~-----------------------------------` ~NewsDisk :` All newsdisks are available for the cost of a blank disk ($6.30). These disks are set up to be bootable workbench disks, and may not give the desired results if viewed from CLI, or after booting from another disk. The third NZAmigaUG newsdisk contains the following : ~Juggler Demo` - An animation demo showing a figure juggling glass balls. Its is displayed in the HAM (Hold and Modify) mode, all the reflections, shadows etc were generated using a ray trace program. It includes sound effects as well. - (from AmigaLibDisk #47) released by Commodore/Amiga ~Wharves` - One of many digitised (digiview) pictures submitted by Warick Wilson (Wgtn) - I hope to include more pictures on later disks. ~Blocks` - A worm like graphics demo in high-res, colours chosen to minimise flicker. Submitted by Gary Walker (Nelson). ~Basic` - A number of AmigaBASIC programs submitted by members : Errmon : Supposed to run as background job reporting error messages - doesn't quite work as you might expect! Submitted by Garth Thornton (Wgtn) Dragon : Draws simple fractal 'dragon' shapes. Try number 6 or 7. Submitted by Garth Thornton (Wgtn) Bands : Hold down mouse button, and move the mouse to operate. Submitted by Garth Thornton (Wgtn) ObEdLo : Modified object editors by Garth Thornton (Wgtn) ObEdHi : Triangle : Select 10, and draw a large shape, then click in the top left corner (under the 'T' in the title) Submitted by Garth Thornton (Wgtn) Ror2 : This one takes a little time to start, originally written by Kevin Bjorke, Submitted by Garth Thornton ScapeGen16a : Solid fractal landscape generator. Try level 5 an variable smoothness. By Garth Thornton. ScapeGen32 : Lores, 32 colour version of above. Contour1 : Contour mapping program, try data file TESTCONTOUR as input. Enter ranges 4-24 for X, 4-13 for Y, 10 contours, and 0.1,0.1 for the two 'courseness' parameters. Program by Harry Trethowen (Wgtn) Other programs were submitted by Harry Patterson (Nelson) and Glenn Blomfield (Bulls), but will have to wait until I sort through them. ~Utilities` - A few useful tools : ViewIlbm : The program that displays IFF files including H.A.M. files like those produced by digiview. Ty : Program to display textfiles from the workbench. Has inbuilt help - use the HELP key. PrintFiles : Workbench utility that dumps text files to your printer. NB the only printer drivers on the disk are 'epson' and 'generic', preferences is set to 'epson'. ~Public Domain Software :` Currently we've got : Aegis Draw Demo, Boing!, (Including multispeed version) CCC Multitasking Demo, Delux Video Demo, Digiview (Australia) Slideshow, Dynamic CAD slideshow, EA IFF 85 Standard, Sept 19, 1986 FAUG Disk #ll, (Anyone got their address?) Fractal Art 1, (From Captain ROM and Co of Titirangi) Future Sound Dukebox Demo, Hippy Art, (From Captain ROM and Co of Titirangi) Musicraft V0.99 Demo, (Three different sets of examples) NZAmigaUG #1.02, (Newsdisk) NZAmigaUG #2.02, NZAmigaUG #3.00, Robocity, Slide Demo, Superbase Demo, WB_THD/DEMO (Molecules). If any of that lot isn't freely distributable, please let us know! If you have other such demos send us a copy - a few that spring to mind are the dancing ballerina, and crying/flying bird demos seen on the video of the Amiga launch, and where is the Aquisition database demo ? Also available are AMICUS disks 1..6,8,9,10 and disks 1..53 of the AmigaLibDisk series assembled by Fred Fish in the States (Fred must spend a lot of time assembling these disks, and has been kind enough to supply us directly (at a small charge) with his disks. I hope you guys (and gals!) appreciate all the voluntary hard work done by the authors of the public domain software, don't take it for granted, try to repay these people by contributing something yourself. And remember, if you like and use any of the shareware products you are expected to send a donation (ussually specified!) to the programs author - this often entitles you to a manual and later updates. If you've got any contributions or requests then send us a disk. (or money to purchase a box of disks, and specifications as to their contents) ~Group Meetings :` ~Auckland :` The next Auckland group meeting ?
