The DOM for January consists of theentire lAC disk *10, some localcontributions and some progra.s takenfrom the Mini'App'Les Librarya Thelater was in existance before the DOMbegam.

GAME SOUNDS EDITORThis program will produce sounds on theApple speaker in accordance with theuser entered values for pitch, duration,rise or fall. The resulting sounds canbe used in ga..s of the user's writing.

From time to time, as space permits,material will be selected from thatLibrary. Please let us know if thispractice should be continued. Most ofthe Library programs on this DO" arefrom Call-Apple.

The first prOQrams on DO" *10 arelocally contributed.

CALENDARFOR PRINTERThe free calendars around the firEt ofthe year seems to have all butdisappeared. With this program and anBO-column printer you can create yourown for many years to come. Line 200may need some adjustment for differentprinters. From the library. By PhillipZimmerman.

STRING SWAP DEMOWhat happens to the Appl £I when you wri tea program to sort string arrays? If youhave tried this, you will notice thatthe sort goes on great for a while, thenthe computer appears to 'hang' for aminute while it does an automatic FRE.This becomes necessary because thestring arrays become defined andswapped.' In the process many unusedstring arrays are left taking up lots ofmemory. Here is a demonstration of aswapping technique that does not createthose unused strings waiting for'garbage collection'. By RandyWiggington.

DISPATCH TABLE LISTIf you do assembly language programming,there may have been times when you havewanted to use some of the routines inthe Applesoft ROMs. This program givesthe entry points for several of theroutines. For further info see the lACmagazine of about a year ago. From thelibrary. Written by Neil Konzen and ValGolding.

AUTO PROGRAMThis program will write some of a newprogram for you. It is an adaptation ofa similar program written for theTRS-BO. Bill DeCoursey has rewritten itto work for the Apple. The prOQram askswhether the user wants st~ndard programparts to be included 1n the newprogram. These standard parts includesuch things as clear the screen, 'get'input, string array set-ups, etc. Theresulting program segment is saved as atext file waiting to be exec'ed into alarger program.

LOGOSome time ago, Tim Pfaff thought the DOMshould have a logo. This logo should besomething that becomes a tradeMark forthe organization. This logo in not quitethe same as the logo used in thenewsletter, 50 perhaps a seperate logocould be adopted for the DaMs. I am notsure how Tim created this logo, butthere is an ample supply for some futureDOMs. Here is another opportunity forcomments.

SOFTWARE NOTEThe next group of programs comes fromthe lAC disk *10. They are a collectionof hi-res graphics demos from fellowApple users in Europe. Some of the filenames are beyond me so I will notattempt to explain them all. Suffice itto say that they all can be 'RUN' andall will produce hi-res pictures ordisplays. Be sure to let the program DABIN ICH run to its completion.

This is a n..., colulllll for ournewsletter. The club receives a largevolume of mail announcing new products,or Making an offer to sell something.Most of these announcements arereplicated in ads that you can see inthe journals. However, some are qUiteinteresting and we will attempt to bringyou a glimpse of those without takingtoo much space. In many cases fUrthurinformation may be obtained by calling aclub board member.

MOUNTAXN MUSXC BOARDMountain Computer has reduced the priceof their Music board from a list of $545to $395. Be careful if you are thinkingof buying one as many stores have stockthey purchased at the old price! Manyof you have seen and heard it at clubmeetings or at Boody's special meetingin Nov. Byte magazine had an extensivereview of it in the July Ell edition. Itis a really fantastic piece ofhardware.

PASCAL GROUP641< RAM BOARD

LEGEND has announced a 64K-byte RAMboard. Thats the equivalent of 4 16kboards on one board. It uses the n...,64k-bit dynamic RAMS, so you only need Elchips. (Incidentily the cost of the64k-bft RAMS has come down to about $9so you may see a lowering in price ofthese boards from their announced listof $350 each.> If you buy two of them,you get a Disk Emulator software packagethat allows you to use the two boards asif they were a single disk drive. Theprice of two boards and the emulator is$700. You can also use the eMulatorwith one board where it emulateshalf-a-disk. The RAM boards are 3 timesfaster than a disk.

Of course you may use the RAM board justlike a Language card too. It uses thesame Device Select Address convention asApple. See 32k Ram board review inNovember Newsletter.

I attended part of the Pascal meeting onDec 2nd. I want to take thisopportunity to thank the Pascal membersfor helping fold the December newsletters? that it might be mailed for a regularfIrst class stamp without the 9 centover-size surcharge.

Keith Madonna started the Pascal specialinterest group about 2 years ago andreally does a magnificant job inproviding an interesting and educationalenvironment for those who attend themeetings. If you are a Pascal user oreven thinking about becoming one go' toone of those meetings. '

EPSON PRINTER NElJSin one place. With use, the ribbonis improving and was OK to print thisnewsletter. I have seen this exactsame phenomenon on ribbons forTeletype 43s.

1. Mr Barden, the fellow in NorthCarolina publishing a newsletter hasmoved to:

136 Candlewick DriveWendell, NC 27591

Information curtesy Joff Morgan, CallA.P.P.L.E.

2. We found a local ribbon re-inker andare trying to get enough ribbonstogether to try him out. We need 12ribbons for the first order. Afterthat, he will attempt to stockre-inked ribbons at about $5 apiece. So, if you have a ribbon youcan let go for about 2 weeks to getre-inked please let Dan Buchlerknow.

Incidentily, Al Peterman when heordered the last batch of ribbonsfrom the Chicago Epson supplier,received a different make of ribbon.They are much more heavily inked thanthe earlier Epson ribbons. In fact,they are so heavily inked that forthe first hour of printing theyblotch badly. Also, if you stopprinting the ink tends to accumulate

3. Al Peterman says that the newerversions of the Tractor Feed option~rom Orange Micro are significantlyImproved due to the inclusion of anextra support roller above theplaten.

4. Anyone contemplating the purchase ofan Orange Micro Grappler Interfaceboard should understand the pros andcons.Pro - it gives you at your finger tipa screen dump and other features.Con - you pay alot extra for featuresthat can be had on a disk free ofcharge and, you get a verynon-standard piece of hardware.Programs that use PR*1 will work OKwith it, but programs that interfacedirectly with the Apple 110 will notwork at all. Examples. theMini'app'les screen dump (of courseyou would'nt need it>, Buchler'sHiprint and similar things which -.ycome along in the future.

5. At least 2 local dealers are sendingpersonnel to an Epson Maintenanceschool and are willing to fix Epaonsnot purchased from them.

Apple 800Ft Keysb!;l Pete Lelia!:I

Function keys are found on many higher priced terminals.They are keys that can be programmed to represent almostanything the user wants. Because they are programmable,they are also called soft keys.

Many of these terminals will also display. labels whichdescribe the function of each soft key. The labels are usuallydisplayed on the bottom row (or rows) of the screen, and; inmost cases, each label lines up with its corresponding softkey on the keyboard. This allows the user to visually connectthe label with the key.

Soft keys can be programmed on the Apple II. Specialfunction keys are missing, but any key will serve. I'veincluded an example that uses the numeric keys (1 thru 4).There may not be a direct label-to-key visualcorrespondence; but, with a small number of soft keys, it isnot so important.

The listing shows a program, written in App lesot"t.that illustrates a way of providing soft keys. The essentialprocedures are at line numbers 31100, 31200 and 31300. Therest of the program is a demo which shows how to use theprocedures. I will describe the procedures in more detail.

Set lli!. LabelsThis procedure, located at 31100, initializes the labels. It ishere that you can give visual meaning to each label. Thisexample allows for four labels of eight characters each, butyou are not limited to that.

Display LabelsTo display the labels, first the cursor is moved to thebottom line. Then INVERSE mode is turned on, each label isprinted, and the program is returned to NORMAL mode.POKE 35,23 causes the labels to be locked on the screenwhile scrolling occurs above them, and the VTAB 1 gets thecursor up out of the locked area of the screen.

Get ResultsFinally, in line 31300, we have the routines which input. theresults of pressing the soft keys. A GET is used, togetherwith a one-character string variable, so that the user doesnot have to press the return key for each selection. If thekey that is pressed is not one of the valid soft keys (1 thru 1in this casel, the GET is repeated. In 31330, the inputcharacter is converted to a number for use in the outerprogram (e.g., line 70). Before returning, the labels areunlocked.

The procedures shown here can be used in any Applesoftprogram which provides interactive choices to the user. Ifnothing else, they serve to further illustrate the flexibilityof the App Ie.

Summarizing Dtack's Newletters 3 thru 5by Dan Buchler

In the October (81) issue ofMini'app'les, you were introduced toDtack Grounded (OS) • For those of youwho did'nt see that article, OS is aproduct forthcoming from DigitalAcoustics of Santa Ana, Ca.

The product consists of an AppleInterface board and a large externallymounted P.C. board with a Motorola 6800016 bit Microcomputer and 4k bytes ofon-board memory. The memory isexpandable up to 92k bytes (not 16 bitwords as reported in last issue) on sameboard, and up to 16.711 million bytes ifyou have enough boards and powersupplies!

The minimum 4k byte memory system pulls0.7 amps and may be powered from theApple itself. Provision is made toseparate the 68000 board from the Applepower bus, so an external 5v supply maybe, and must be, used for larger memoryconfigurations. OS will not supply thatpower-supply. The price for the 4kconfiguration will be $775. A pictureof the configuration is shown below.The 'little' Apple Interface card may beseen with the unpopulated 4k mainboard. The 68000 MPU is the large IC onthe left of the big board.

DG will also market an expansion board(to help you reach 16.711 millionbytes). THe board will have space for128k bytes. Since they had space leftover (the expansion board is the samesize as the main board), they plan toinclude a Mpink marble statuette of anaked lady with a clock for a navel Moh; excuse me, OS later modified that toinclude a real time clock (that works)instead.

where the Applesoft Interpreter mustperform the equivalent of

a. Routines to allow the 6502 tocommunicate with the 68000.

b. The 68000 floating point code.c. Some simple modifications to the

RAM (language board) residentApplesoft to link the floatingpoint operations through thecommunication routines (a) into the68000 code.

Floating point operations are requiredeven in the most mundane internalbook-keeping type software such aSI

To those unfamiliar with themicrocomputer industry, the 68000 is theking of micros. It is expected to bethe processor for the next generationsystems. It is super powerful. Rumoursabound that announcements of 68000 basedsystems are imminent from Tandy andApple!

In DS"s first release which is expectedat any moment (in fact you may order onetoday), the 68000 will perform theFloating Point manipulations. This itcan do much more efficiently than canthe 6502 in the Apple. Later versionswill rely on software support fromsoftware houses such as those engaged incompiler writing in order to makegreater use of the 68000"scapabilities.

FOR 1=1 TO 10001 ••••••••• NEXT

In order to make the 6BOOO do thesefloating point manipulations, DB willprOVide software which will work inconjunction with a "language board" (orany upper 16K expansion board). Thatsoftware will among other thingscomprise:

OS will provide an initializationroutine (probably written in Applesoft)which will cause the 68000 FloatingPoint code (item b.) to be transferred

from the 6502 RAM into the 6BOOO RAM(4k+) so that the whole kaboodle canstart working.

DG has published alot of benchmarkresults using their board on a PET (CBH)with which for some unfathomable reasonthey decided to initiate development.The PET also utilizes the 6502 MPU andan almost identical version of MicrosoftBasic. Because of internal hardwaredesign constraits, the PET Basic isabout 157. slower than Applesoft. Inthose benchmarks, they have extrapolatedthe speed improvement which might beexpected using a compiler such as theone sold by Hayden. Two of theirbenchmarks were;

A B=SQR(3);FOR 1=1 TO 5000;A=B/laNEXT I

B FOR 1=1 TO 5000:A=LOB(I):NEXT I

Benchmark Times* SpGfid_RatioA -B A B

ApplesoftInterpreter 29.3 127.B 1.0 1.0+ 6502 FPU

Interpreter+ 68000 FP 17.7 20.9 1.65 6.1

Compiler+ 6502 FP 16.2 116.5 1.80 1.1

Compiler+ 68000 FP 4.6 9.6 6.4 13.3

**FP=Floating Point* DG's Interpreter times reduced by 2.6seconds to allow for improved spGfid ofApple over PET

Notice that the compiler itself improvesthroughput by no more than 1.Bll for theparticular benchmarks used here. Thisis consistant with reviews of compliersreported in Mini'app'les, Softalk, CallA.P.P.L.E, etc. The reason is that asignificant portion of the interpretertime (14.8 seconds for Benchmark A) isused up by Interpreter overhead. Thus,a compiler makes most impact in a numbercruching application rather than in alogic or text processing application.This is of course the opposite of theimpact gained by use of the DB board.For bechmark B, the overall throughputincluding the compiled code is 13.381

Now, DG is encouraging one or moreCompiler writers to make a version foran Apple with a DB board. Futher, ifthat compiler allows variables to bestored in 68000 memory space rather thaan

in 6502 memory space, then the nGfid totransfer the data from 6502 to 68000memory and back again is eliminated. In,such a situation, the 13.311 numberabove would then become 16.711. In suchan environment, the 6502 perfor.. thelogic and 110 and the 6BOOO does thecomputational work (something like theZ80 board).

In closing the subject of spGfid, it mustbe noted that many factors effectthroughput. A large Applesoft programruns slower, and one with many variablesruns slower. Th. DB board does nothingfor that. A compiler will h.lp thatsituation. The ultimate solution to allof this is to have a compiler whichgenerates 6S000 native cod. l.aving the6502 to do nothing but the 110. Th.n,your sp.ed improvements would b. maybetwo times again. Moreover, if you havea fully populated 6BOOO board, one canget much more .fficient use of memorysince the 68000 is a 16 bit machine witha vastly superior instruction set.Again, such a development is not outsidethe realm of possibility, though DBleast of all is making no promi ....

According to DS the 68000 is really aneat computer to program in AssemblyLanguage. " ••••••••• ther. is absolutelyno comparison whatever in the ease ofprogramming a particular applicationbetween it (the 68000) and the 6502. The68000 wins hands down." However DBrecognize that the 6BOOO is a newmachine with alot of new syntax. Tohelp in the education process, DB willprovide with their board a menu drivenprogram that 'walks' through the syntaxfor all the options for a particularinstruction.

Well thats the meat of DB'S last 3installMents. Now I await a letter frOMHal Hardenbergh, president of DB,telling me I am a 'cur' for .-ntioninghis pink lady!

by Keith Madonna

Apple computer has come out with anotherfine product, called 'PROfile' It is asyou may have guessed, a hard disk. Nowfor a few details:

Apple NewsThree pieces of hardware are shippedwith the unit:1. 25 conductor cord.2. An interface card which plugs into

one of four slots in the Apple III.3. The hard disk & power supply (all in

one unit).

Also two pieces of software come withthe disk:1. A 'PROfile' driver diskette,2. A demonstration diskette.

In the flyers sent out by Apple arementioned two new software packagesbeing released: Applewriter III, andMail list manager.

By the way, the disk drive cannot beused to store Apple ][ software in anymode, even emulation mode. Data orprograms have to be in Apple III formatto be saved to the hard disk. All newsoftware releases will be made with thenew version of S.O.S. 1.1. The cost ofthe hard disk package is $3495.

Also about to be released by Apple are:A memory board which will boost yourtotal memory capacity to 256k.A new Apple III monitor for '$322(which comes in black/white or greenscreen, both non-glare). This monitoris the best I have seen to date.Another card for inside the computer;a Universal Parallel card threeparallel cards in one for $225.

Now for some dimensional data:Height 4.39in.Width 17.28in.Depth 8.8lin.Drive weight 111bs. including powersupply which is built into the unit.

- Drive ready to operate from cold startin 60 secondsAverage seek time 95 millisecondsData transfer rate 5 MegabitslsecondData may be transferred one byte at atime, or by direct memory access (DMA)at one Megabyte per second. The DMA isaccomplished by disconnecting theApple III processor, and transferringinto memory under of the hard diskprocessor. The disk 110 speed can beincreased by a software change, whichdisables file verification on writing(default is verify on a writeoperation) •

It can store about 5,013,504 bytes, orsimply 5 Megabytes, or about 1200 pagesof single-spaced typed text, or as muchas 35 conventional floppy diskettes.This storage is accomplished using 4surfaces (2 platters of 5.25in.diameter), with 153 tracks per surface,16 sectors per track, and 512 bytes persector. The drive characteristics are asfollows:

The hard disk motor speed is controlledby a built-in card, which maintains aspindle rotation speed of 3600 RPM, plusor minus 1%. On a cold start the disktakes 20 seconds to reach it's operatingspeed, and an additional 40 seconds todo a check on the surface media, beforedata can be stored. Thus, nominal startup time is 1 minute. However, if theverify detects an error, variouscorrecting procedures are attempted. Anabort will only occur if the system hasbeen unable to bring the system on-linewithin 3 minutes.

The disk drive also has a mechanicalbrake to stop it quickly whenever poweris removed. This is important onlybecause the heads (4) are in contactwith the surface during start-up, andshut-down.

Another important point is the time ofin-use hours between failures; that ismean time between failures (MTBF). Thisis specified as 10,000 hours.
