TS1000/1500/ZX81

An unusual graphics program using the unique graphics of the ZX81, by Daniel Richardson. The graphics characters for each line can be accessed on the following keys:

110: _/_/6/6, _/8/6/3/5, _/8/3/4/5, _/_/Y/T
130: A/H/H/ H/H/A
150: A/G/G/G/G/A, H/□/□/□/□/H
170: _/□/5/8/□
190: _/A/A/H/H
195: □/□/□/□/□ /□/□/□/□/5/E/1/2/R/8
Note: □- Graphics- space.

I’m afraid I’ve lost track of who sent in this program, but I think it was TSH author Richard Watts. It’s a very interesting music program: play the keys q,w,e,r,t,y,u,i,o,p,2,3,5,6,7,9 and 0 to play songs.

 10 LET a$="q2w3er5t6y7ui9o0p"
 20 DIM b(256)
 30 FOR c=1 TO 17: LET b(CODE a$(c)+1)=c
 40 NEXT c
 50 LET d=CODE INKEY$+1
 60 IF b(d) THEN BEEP .5,b(d)-1
 70 GO TO 50

  5 REM PROGRAM FOR TS-2068 by JOEE JENKINS, [address omitted], AMARILLO,TX 79109. Date is 11-NOV-85.  W5JEN
 10 REM SPIRAL , a conversion by Ted Knyszek  from APPLE II to TS-2068        See CREATIVE COMPUTING  FEB 1984    FEB 1984
 15 REM the PI in Line 20 is the GREEK LETTER PI, A SHIFTED M , you see.
 20 LET c=COS (PI/3)
 30 LET s=SIN (PI/3)
 40 LET c1=COS (PI/36)
 50 LET s1=SIN (PI/36)
 60 LET sf=.95
 70 LET x=95
 80 LET y=0
 90 LET cx=130
100 LET cy=88
110 LET sc=1.16
120 FOR j=1 TO 43
130 FOR i=0 TO 6
140 LET sx=x*sc+cx
150 LET sy=cy+y
160 IF i=0 THEN GO TO 190
170 PLOT sx1,sy1
180 DRAW (sx-sx1),(sy-sy1)
190 LET sx1=sx: LET sy1=sy
200 LET xn=x*c-y*s
210 LET y=x*s+y*c
220 LET x=xn
230 NEXT i
240 LET xn=sf*(x*c1-y*s1)
250 LET y=sf*(x*s1+y*c1)
260 LET x=xn
270 NEXT j
280 STOP

This program was converted by Joe E. Jenkins from an Apple II program. For a different look change the upper limit in line 120 to something besides 43.

TS2068/Spectrum or TS1000/1500/ZX81

This little program was submitted to Try These by Dave Johnson. Listing No. 1 is written for the TS2068 with the OS-64 cartridge from Zebra Systems. We haven’t tried it on the TS1000 but the effect on the 2068 is very interesting. Also try it without line 21.

  2 FOR a=1 TO 20
 10 PRINT AT a,a;"▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒"

This is an early program written by TS Horizons author Bernard Bush. We borrowed it from The Best of SYNC, Volume 1. Don’t miss next issue’s feature by Mr. Bush, a collection of TS 2068 graphics programs.
