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.
