It's an #apple1 #BBS kind of night

Of course I had to log on to Mastodon on the #DEC #VT420 - maybe someday I'll make it prettier but it works.

Up close and personal with #Colossus

Sneak peek: This #ZXSpectrum issue 3 will move to the replica board on the right. I have to wait for delivery of some more components, but I am particularly looking forward for this #RetroComputer project. I will keep you updated, of course. 😀​

Here's a quick #c64 demo I wrote to refresh my #basic #programming skills.

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!
