Dear Les,

Congratulations on another good issue. In fact so good that I am enclosing my subscription for the next six issues.

Grab an Apple is one of the best magazine programs that I have found published anywhere, it is short and sweet. Having said that, I. now offer some small improvements which I find make it even more playable.

220 HX=HX+DX:HY=HY+DY:LOCATE HX,HY,Z:SOUND 0,100,12,4:SOUND 1,COUNT*4,10,4

225 COLOR 161:PLOT BX,BY:COLOR HEAD:PLOT HX,HY:SOUND 0,0,0,0:SOUND 1,0,0,0

235 W=51:1F STRIG(0)=0 THEN W=SPEED+1:C0UNT=COUNT+l

248 COUNT=COUNT-1:IF COUNT THEN FOR I=1 TO W-SPEED:NEXT I:GOTO 170

These modifications add on an extra sound to let you know that your time is running out (lines 220,225) and give you the opportunity to speed up the caterpillar by pressing the fire button, gaining extra points and improving the early stages of the game (lines 235,240).

Dear Les,

I am very pleased with PAGE 6 but I was wondering if you had any plans for articles on how to use Atari computers for other purposes. I am interested in amateur electronics and every month see D-I-Y interface boards for other computers but never Atari. Any information on this subject would be of interest to me and I am sure to many other users as well. I have never even seen any information on the 850 interface but at over 100 it does not seem good value when compared with D-I-Y projects for other computers which can be made for about 15. Even the Input/Output ports on the Atari seem to be a secret. Can any of your readers tell me what the pins are on each port or where I can find the information?

** I would be happy to feature articles on hardware projects but rely on readers to send in articles. One or two people have promised articles of this nature and as soon as they are received you will see them. Among the projects which other users have built are a speech synthesiser for 25, a rapid-fire joystick trigger, an infra-red burglar alarm and various modems including a hook-up to Micronet. If any of these people wish to share their discoveries they are free to do so in the pages of PAGE 6. I don't understand the hardware side of things, but it is exciting to hear some of the projects others have designed or built.-Ed.

Dear Sir,

Having got stuck on Adventures, I have often wanted to PEEK memory to get some clues but the Reset on the Atari does not enable you to get back to Basic to write the program.

For those with a Disk Drive, the solution is so simple that I wondered, why I hadn't thought of it before. Simply choose selection C of DOS and print the program to the screen, e.g. PYRAMID,E:. Then using CTRL-1 you can stop the listing where you want to.

Dear Sirs,

I am much impressed by Tiny Text in issue 2. Your readers might like to add the following lines I have included because I required an underlined title. This is for use with an Epson printer.

The Control Codes included are:

CTRL-U underline following text

CTRL-O turn underline off

115 TRAP 120:0PEN #1,8,0,"P:"

729 IF B=21 AND OP=3 THEN ? #1;"[ESC,ESC,MINUS,CTRL-A"

730 IF B=15 AND OP=3 THEN ? #1;"'[ESC,ESC,MINUS,CTRL-COMMA]"

830 IF OP=3 THEN ? #1;SP$(1,SP);A$

Finally, change LPRINT to ? #1 in lines 725,727 and 815.

Without changing the program further, it is only possible to underline all text on a line.
