EDITORIAL

Well, the newsletter is definitely late this time. It's partly my fault because I've been so busy at work (overtime ad nauseum). As editor I tend to be a little proprietary about Sine-Link ("It's MY newsletter and I'll get it out when I'm good and ready'.") so offerers of help tend to get their hands bitten. I am mellowing a little, though, and Pres Rene Bruneau will take a crack at producing the July - August issue (1*11 be watching him like hawk).

As I said, I am partly to blame for the delay but the other reason is that in the last couple of months we have seen a marked decrease in the number of letters/articles coming in. Why is that? We have more out-of-town members than ever but we're getting less material from them. Surely we can't have discovered everything about our computers. There must be something you've found that you haven't seen published, so why not write about it.

Give it a try and I'll try to be more on time, editorially- speaking. 'Nuff said.

RHODE ISLAND UPDATE

As mentioned last issue, here is more info on the QL-fest being held in Newport, Rhode Island.

The get-together will be at the Salvation Army Building on Memorial Boulevard, Saturday June 5th. Show times are 1 PM to 6 PM. Contact Bob Dyl of IQLR for more info (401 )-849-3B05.

Our own Hugh Howie has reserved a display table for the Toronto Timex-Sinclair Users Club. Hugh will be manning the table, possibly with one or two out— of— town members, handing out lots of promotional stuff about the club and also running an elaborate demonstration of the QL's abilities.

Hugh expects to meet lots of new faces, including some U.K. software and hardware vendors, generate new memberships, attend all the pre- and post-fest talks and dinners and find time to run his demonstrations. Whew, he'll need a week to recover. Watch for his impressions and articles of the fest in the next issue.

BAD NEWS FOR NESQLUG

Just prior to publishing, Hugh phoned to inform me that the Director of the New England Sinclair QL Users Group, Ernest Wider, died suddenly on May 31st. Our condolences to his family and NESQLUG.

SO LONG, SINCLAIR USER

Courtesy of out-of-town member, Robert Shade, I have included an article on the TS2068 lifted from the pages of the last issue (March 1993), of Sinclair User magazine from the United Kingdom. This article might explain how a few U.K. vendors (ie Doctor Dark, PRISM PD, etc.) found out about some of the clubs on this side of the pond. Sorry to see another Sinclair-related publication fold. To my knowledge, only Your Sinclair remains in publication in the U.K.. Thanks for the info, Robert.

That's all for now ... J.T.

INDEX. B1 By George Chambers TS2068 Larken

In our TS2068 Larken library, buried in Disks #02 "OMNIBUS" and Disk #33 "PULL-DOWN (Menus) OMNIBUS" is a utility called " index. B1 ". It is designed to maintain an index of the contents of any collection of Larken disks. One simply feeds the disks into the program, one by one, and it reads and stores the contents of the disks. One can then search, sort, and print out the contents to screen, TS2040 printer, or to a large printer. The program was written by Bob Mitchell some time ago.

A later refined version (VI .11) is found on Disk #47 "UNIQUE PROFRAMS", and the refinements described in this article are applicable to this version. Ask for this disk.

When Bob Mitchell wrote this program he incorporated within it the ability to detect whether the selected printer, TS2040 or large printer, was ON or OFF; and to display the cond it ion on the screen.

The problem with this feature was that not all printers supplied the same signal info as the Fastext 80 used by Bob. And if the signal for the ON cond it i on was not the one Bob had incorporated in his program, one could not continue with the PRINT feature of the program.

There is another feature of the program which may be customised to your part icular needs. Many disks contain an AUTOSTART file and/or a "menu" file. An option was provided which allowed these two filenames to be NOT printed out. Later, I expanded the feature to include two more f i lenames to be s im i lar 1 y excluded from the pr intout ; f i lenames "taswi", and "help". The program listing below does not provide for changing the AUTOSTART filename, since it is so univerdally used.

The method used to make these changes is to POKE them into the appropriate addresses in the " index. Cc" code. The following listing will do this task. All you need to do is determine your printers' ON/OFF codes and enter these values in the var tables. And to enter any changes in the f i lenames .

To determine the printer ON/OFF signal codes, run this short program: 10 PRINT AT 10,10;" "; AT 10,10; IN 127

20 PAUSE 10: GOTO 10

Switch your large printer into it's OFF and ON (ready to print) modes. Write down the values, and then enter these values into the variables LPOFF and LPON in Line 150 of the listing.

Change the IN 127 in the above listing to IN 251. This will check the 2040 printer. Probably this will not need changing, but if it does, then do the same thing. Record the values and place them in variable TSOFF and TSON in Line 160.

150 LET LPOFF =127: LET LP0N=108 160 LET TSOFF =126: LET TS0N=56

MULTIPLYING BY TWOS Rene Bruneau

Here is a quick programming trick that I learned to convert binary numbers to decimal. Starting from the most significant bit ( MSB) - the one on the extreme left - multiply it by 2 and add the result to the bit to the right, then multiply the new result by 2 and add to the bit to the right, continuing the process untill there are no more bits to process.

Example: 1001010 = 74

0 =

Because you double and add to the right, the arithmetic is simple and can be done in your head - no need to go looking for a calculator or conversion tables. Besides you can always impress your friends and fellow programmers with your computer-like brain maybe --.

Q L I P S

by Hugh Howie

SUPER DISK INDEXER

Recently I came across something we could all do with. A program to help us keep track of our disks, and what is on those disks . This program is called SUPER DISK INDEXER, written by Imre Dominik, and available from Dilwyn Jones Computing at the very modest cost of £12.00 and worth every penny.

The program will keep track of all your disks and cartridges by setting up a database of the contents of your media. You don't have to type very much as the DISK INDEXER reads the contents of your disk or cartridge direct into the database .

You can then use DISK INDEXER to search for a title anywhere in the files.

The first thing to be done is to put your disks in order and give each one a number, and writing that number on the disk itself. Load up DISK INDEXER and follow the simple instructions. Yes it does take time to do all this, but the hardest, part is getting your disks in order, and swapping them in the disk drive. The reading is doen so quickly you are kept busy.

This program requires at least 256K extra memory, but as most of us now have that, it is really no hardship.

Can handle up to 999 disks with up to 480 files to each disk - now how many files is that? Of course if you run out of space then you can start up another file under a different title. Have you got that many disk/files? How do you keep track of that number without an indexer to help you?

It is time you had this little beauty, I have foound it of real value in tracing down exactly where a certain file is.

I would not be without it. Now here is what Dilwyn Jones has to say about it in his catalogue .

DISK INDEXER

A really easy to use aid to indexing your floppy disks and cartridges. Sets up a database of the contents of your media (reads the contents directly from the disk or cartridge, you don't have to type it all in) and can handle thousands of filenames on up to 999 media (subject to amount of free memory) . You can then search, sort (filename or disk number order) and print the contents of the media. Can't remember which disk that file is on? Search for it using Disk Index - if you know the filename, do an "exact" search, if you don't do a "vague" search. Easy to update the database if the contents of a disk is changed. Works with numbered disks - you simply write the number of the disk on the label and enter it when asked by the program as it reads the directory automatically. Can give you lists of disk contents, lists of unused numbers and so on. This program will really help you to get your disks organised! Super Disk Index needs at least 256k extra memory on a QL. NB can only handle up to about 480 files per disk, so the current version may not be adequate for cataloguing ED disks if you pack them with larger numbers of files! Ideal for cataloguing lower density disks and microdrives. Ideal companion program is our Disk Labeller program, described elsewhere in this catalogue. DISK INDEXER (on disk or mdv) ... £12.00

April 5, 1993

Mr. George F. Chambers, Secretary Toronto Timex Sinclair Users' Group 14 Richome Court Scarborough, Ontario M1K 2Y1 Canada

I mentioned last time that I had made an offer for a 3 00

baud modem/serial interface from Byte-Back's "Make David an Offer" sale, but hadn't heard anything. Well, the package came in the mail the other day, and believe me, it was worth the wait. I had asked David Leech in my order if I could get copies of both 2068 and 1000 terminal programs (assuming he normally provided such software with the modem), since I had both 2068 and 1000 (1500) units. Mr. Leech did indeed send both 2068 and 1000 tapes, not only for terminal operations but also for utilizing other serial devices like a printer with the serial interface. He replied in the letter accompanying the order that the modem was intended for use with either a 2068 or a 1000 unit, but not both, and had to be hardware configured for the appropriate model. However, since I apparently wanted to use it with both kinds of units, he had added a switch for me so I could change back and forth! I had also mentioned in my order that, when I had gotten a parallel printer cable from him a few months earlier, I had not known to request 1000-specif ic software to accompany it, and as a result he had sent only the software to have the cable work with my 2068. In his package, Mr. Leech tossed in the 1000 parallel cable software and the instruction sheet! This is clearly service well beyond the call of duty; the T/S world is going to be losing not only a vendor but a true T/S enthusiast when the Mr. Leech's closeout is completed. For people who want to get some of the remaining goodies, his address has changed very recently; it is now: 53 6 Long Terrace, Leesville, SC. 29070 (USA) . I'd strongly urge anyone with a need for a peripheral/ interface to get an order in now!

ANALOGUE "to

1 RESOURCES DIGITAL CONVERTER

Rent Bruneau Hay 1992

s analogue to digital converter is a simple design based .. the ADC0804. It will convert voltages up to 5v into a fori that your computer can translate and display for you. In the present configuration, a LH335 is used to convert temperatures froi 0 to 100 *C to a voltage that the ADC can sample.

CONSTRUCTION:

Loading the components on the PCB is straightforward. Hake sure that CI and C2 are installed correctly and note that pin 1 of U3 faces pin 1 of Ul and U2. An address block (P2) allows you to tap the board to port 191 or 127. The temperaiure probe is assembled using the LH335 mounted in a Bic pen tube. Seal the ends with epoxy or silicon sealer to protect the connections to the LH335.

CALIBRATION:

To calibrate the ADC, you will need a thermometer, a glass of ice and water, and a glass of freshly boiled water.

Tor a 2068, use the following procedure:

Enter the following program:

10 OUT 191,0 20 PRINT AT 0,0: ' ' 30 PRINT AT 0,0; IN 191 40 GOTO 10

On running the program, place the LH335 in the ice water and after a couple of minutes, adjust RV1 until you read 0 on the screen. This is your minimum temperature setting. Now, place the probe in the hot water alonq with the thermometer and wait for the readings to stabilize. Adjust RV2 to match the reading on the thermometer. Recheck the probe readings in the ice water and repeat the calibration until you are satisfied.

For the ZX81, you have to install a small machine code routine to provide the IN and OUT commands. Use the same procedure as above to calibrate the ADC.

Load the following:

1 REM 12345678901234567890

10 FOR X = 16514 TO 16524

20 INPUT A

30 POKE X, A

40 PRINT X}' PEEK X

50 NEXT X

At the prompt enter these values:

62, 0, 211, 191, 201, 219, 191, 79, 6, 0, 201

Replace lines 10 - 50 with the following:

10 RAND USR 16514 20 PRINT AT 0,0; 1 ' 30 PRINT AT 0,0; USR 16519 40 GOTO 10

Once the ADC is calibrated, you can embelish the program, adding all the bells and whistles you want.
