Here it is plotting

"Fedora" plot...
(I converted to BBC BASIC from Atari 8 bit listing on AtariAge forum)

1 MODE 0
2 VDU 19,1,1,0,0,0
3 DIM RR(320)
4 FOR I=0 TO 320:RR(I)=193:NEXT I
5 XP=144:XR=4.71238905:XF=XR/XP
6 FOR ZI=64 TO -64 STEP -.5
7 ZT=ZI*2.25:ZS=ZT*ZT
8 XL=INT(SQR(20736-ZS)+0.5)
9 FOR XI=0-XL TO XL STEP.5
10 XT=SQR(XI*XI+ZS)*XF
11 YY=(SIN(XT)+SIN(XT*3)*0.4)*56
12 X1=XI+ZI+160:Y1=90-YY+ZI
13 IF RR(X1)<=Y1 THEN 16
14 RR(X1)=Y1
15 PLOT 69, X1*4,800-Y1*4
16 NEXT XI:NEXT ZI

I ran @rheolism's program and got this.

This is AWESOME! Portal! Yes, PORTAL! On the PET!!!!!! And it's fantastic!!

Just in case you missed the game release of the year, here's a little capute of the intro from #EyeOfTheBeholder for the #Commodre64 - thanks to @Herr_Irrtum fir posting the relase link (https://www.pouet.net/prod.php?which=92920)

You'll need a way to store the CRT file of the game (e.g. #EasyFlash or #KungFuFlash or whatever else does the trick).

P.S.: the white line on the left is an artefact only seen on my captured video. The actual game does *not* show it.

Pretty close, I'll let that prediction pass. (BYTE Magazine, 1981)

Thanks to @petestevens at @beasts for this brilliant step-by-step guide.

Super Star Trek, which I have converted from the original 1970s (80 column printer terminal) source code. Now for the #Commodorer64 with some sympathetic enhancements such as NAVigation and TORpedo helpers. It's not perfect, but getting there. Still deliberately terminal based!

Introducing the first alpha release of Mastodon 3.11 for Workgroups!

Available for Windows 95

It's funny. It's only now that I've made a .gif of the old Boing Ball demo, and I see it before it animates, that I realize exactly how they did it. There's no animation of the ball. Just colour-cycle it, and let the Amiga's hardware move it around. Genius. 🤓

Not sure why it never occurred to me to try my favorite retro demo program on an 80 column PET. Universe wrong now righted. Happy Wednesday! #commodore #PET #retrocomputing
