The originai version of this croagram was written in Micro- soft Basic by author George Steniart and First appeared iff the Dec. 19823 issue of POPULAR COMPUTING (with corrections iff the March i984 issue}. Please re rer -to this arti ere for @ complete description of how the program warks. It. 28-4634 complicated and ingenious. FneigGhbor af mine named Jim Payne next converted it to fun om his TI 8@O74A computer and I worked from his version to make it run on the' TvS 2068 computer amd 2@4de printer.

IT went through about twenty remrites ta get everything cperating carrectty and I have Lte€etted the Foltawing Printout Pretty thorought Os I am sure there if always room for improvement hoamever, and I would be anxiaus ta hear oF any.

TI did mot Find any reasons why the program caouvid not also be modified to work on the TS 1808+ 4588. This wouid be a good eroject Far sameone and I would be glad to talk it over if amnigone is interested.

When typing in published programs for the 2068 you must keep in mind that a program line can be entered wrong even though it reads exactly the same as the line being copied. Consider the line: 10 PRINT AT 6,15;°R®

The R in the above line can be typed in with the cursor in either the L mode or in the graphics G mode. If you are as innocent as I was you would probably type in the R usint the L cursor mode. If R is made into a user Gefined graphic character (see Chapter 186 of the

~—~3068 User Manual) somewhere in the

program, you can have trouble. If R has been entered using the L

-~cursor mode, the R will print ou

as R when the program is RUN, but this might not be what is wanted. If R has been entered using the G mode, the user defined graphic will be printed out. The graphic symbol will appear in place of R when the program is brought back on to the screen after it has once been run. The lesson to learn is that if you are typing in a _ program for the 2068 you must study the program to determine if letters "A" to °0* should be typed in the L mode or in the G mode.

A second source of trouble occurs when typing in the graphic symbols found on the number keys 1 to 8 using the G cursor mode. If you are a little hazy about how to type these graphic symbols, you are apt to get into the INVERSE VIDEO mode part of the time. This won't keep you from making the string of graphics from looking exactly the way you want it to look, but the running of the program may 0be stopped by an error signal. In my particular case the error signal °K - Invalid color® came up further on the the program. This was puzzling since color did not seem involved. I had much trouble finding the fault. Keep in mind that if you get into the inversev video mode, the cursor mode symbol will not change to indicate it.

The First Bug

It was the summer of 1945. The US Navy

was rushing to finish Mark II, the

first American large-scale digital computer. “It was a hot summer with no air

conditioning, s0 all the windows were open,

Hopper in the Annals of the History of Computing

” wrote Navy Captain Grace ing. “Mark II stopped, and we

were trying to get her going _ We finally found the relay that had failed. Inside the relay-vand these were large relays—was a moth that had been beaten to death by the relay. We got a pair of tweezers. Very carefully we took the moth out of the relay, put it in the logbook, and put scotch tape over it. Now, Commander Howard Aiken had a habit of coming into the room and saying, ‘Are you making any numbers?’ From then on if we weren't making any numbers, we told him that we were debugging the computer. To the best of my

knowledge that’s where it started.” This

i logbook page, with the first computer bug still taped to it, is at the Naval Museum at the Naval Surface Weapons Center in Dahigren, Virginia.

Thie program is @ fun and easy to use tool. It’s possibilities, are quite extensive, and range frow a siaple sketch pad to- complete GRAFIC DESIGNS, as wel) as VIDEO DISPLAYS and so on.

There are various modes, (which wil) be explained in detai)) these include. Draw, TITLES, TEXT entry, DISPLAYS of TEXT or “PICTURES”, saving & loading of eratic “files” setting PRINTER and so on.

One of the important features, are the 3 STORE/RECALL pages. These hold in memory, complete ecreens (colour H/R grafice TEXT, TIILES, etc, and can be used for any purpose, including ANIMATION or EDITING.

Following, are operating instructions for the various modes.

1-DRAW.. You can either use the JOYSTICK, or KEYS 1-8 (1-4 are for @iagona) soves). To wipe out (erase), hold down the firing button on the joystick, or prece key 0. If you use the keys, then you wil] have to press key 9 in order to return to normal drawing. The various sub sodes and their keys, are displayed on the scre.n at al) times.

Before the drawing i6 actually activated, (or at any tise you wish), the colour options wil) be displayed. These will always follow in the same order of input, PAPER bright or normal, PAPER colour, FRAME, BRUSH, PEN, TITLES, CHARACTERS.

- BRUSH, is triple high resolution plotting, and thercfore is slower then PEN.

C-chrctr.. you will be prompted for an input of any keyboard character including the grafice. Note.. do not enter more then 26 at one time, as screcn may automatically scroll upwords. Chretre will be printed on the line of your last drawing position. Note.. FLASH applies only to these characters, and is turned on and of with key F.

E-erase.. will erase the entire screen (leaving the frame), and retaining al] previous positions and colours or sub modes.

O-over will print or draw over without erasing, N-normal cancele O-over. M-menu exits the DRAW pode.

S-store.. You will be prompted for the page number (1-3) and the picture and frame will be stored in that page. This allows you for eg, to start a drawing in certain colours, store it, then experiment for a while, either cont storing, or recajl the original and go on. Therefore, it is advisable, before any changes, to store the existing screen.

R-recal].. will of course recall] any of the above mentioned pictures.

T-TITLE.. Titles will aleo be printed on last drawing line, however since these are of variable heights and widths, care should be taken when specifying their dimensions, as they erase everything in their path.

The TITLE sode can also be accessed seperately (MENU item 3), placed in storage and later recalled in DRAW mode before FRAMING or drawing over.

I-ink will return to the above sentioned colour prompts. Note.. We have included the “CHAMELEON” colour, which allows the PEN, BRUSH, TITLE, chrctr, etc to adopt the colour of its

nearest plotting positions.

Z-CIRCLE.. after entering the diametor, the computer will automatically, draw @ circle to the right of the last PLOTTING position, (unless your specified size is too large for that area)

ve picture left. Y-move picture right.

"hesee gon will ecroll the picture sideways in the above directions. Assuming you have & drawing, and would like to erase the right side, every time you press X, the picture will wove to the right, therefore erasing that side, and bringing the left side 1 step closer to the center.

NOTE.. all af the above mentioned “submodes”™ and features can be used individually or in any combination. Please experiment & "PLAY" for a while, before attempting to recreate the "MONA LISA". As you can see from the examples in the program, the possibilities for creating “GARBAGE” are also quite extensive.

MENU item 2-ENTER TEXT.

This mode is used for creating DISPLAYS (including TITLES), for VIDEO, (credits, advertising etc).

The regular text is automatically “PROCESSED” (WORD WRAPAROUND) etc. TITLES are entered at the same time, the difterence being as follows.

l- Enter an aeterik (symbl shift 8B). 2- now enter your

TITLE, (max 29 characters long). 3- Enter another asterik. The asteriks at the beginniig and end of the titles, tell the computer (upon DISPLAY), that the text contained between them,

should be enlarged and displayed in a seperate lings end perhaps cclour. To create a “proper” display, enter text and TITLES seperately.

When entering the TEXT (since the computer is in input, gay we surgest.. that you onter every paragraph seperately. The “FILE” cam hold eproximately 1100 characters including the ones used for TITLES. All files are automatically saved and loaded tcpether with the 3 “PICTURE pages". Between entries of TEXT or TITLES, you can at any time, start from scratch or continue the TEXT in memory, which can be optionally displayed before new input. Note.. TEXT and TITLES can not be EDITED after entered, therefore Take care and do all your planning and editing while in input (" ").

REMINDER- every seperate input will be treated as a new prerp MENU item 6- DISPLAY/PRINT.

This of course will bring us to “the somgent of trouth”. Following will be 4 SUB MENU iteas.

1-VIEW (animate)- will display the 3 “PICTURES” every time you hit the key for that page (0 will exit that SUB mode). This can be affectively used for animation, and recorded on a VCR, as there are no prompts or any information displayed on the screen.

2-DISPLAY TEXT/TITLES—- will do the same for the TEXT/TITLES and will automatically scroll up and repeat, until any key is preesed.

3- COPY pictures to printer- Will automatically printout the 3 pages, (TIMEX or CENTRONICS type DOT BMATRIX printer.

4-TEXT/TITLES hard copy- will

above mentioned printers, but centronics interfaced printers.

S- Will return you to the main MENU.

MENU item 4- SET PRINTER .. you have to pass through this pode if you are using a CENTRONICS INTERFACE type PRINTER. This prograe includes a MC driver routine for sost popular CENTRINICS printers.

MENU item 5- SAVE/LOAD- enter name of file (mark cassette label if you are saving). This ends these instructions. As usual, this prograg is bug free, PLEASE TAKE YOUR TIME in discovering its uses.
