- 1k ZX-81 Wall-run
- WALL-RUN is for the ZX80/ZX81, (1k or 2k+), and is a simple open source machine code game.
The zip file has the source code, "zwall.asm" and 4 executables:
ZX81: zwall1k.p and zwall2k.p
ZX80: zwall1k.o and zwall2k.o
Use the keys "WADX" (W=up,X=down,A=Left,D=Right) to control your wall and trap the computer opponent. When you do, you progress to the next level. You have to trap the computer twice on level 2, 3 times on 3, etc.
Collect bonuses ($) for points, they score more on higher levels.
The level number (1-9) is shown on the top bar.
The 2k+ version has a bigger screen, score/high score and title screen.
Note that the souce code can conditionally compile the same code to ZX80 or ZX81, 1k or 2k+. This code demonstrates how you can write programs that work on both systems.
Is this the first pouet prod for the zx80? - isokadded on the 2025-06-15 11:21:55

- demo Commodore PET Hawaii
- This is the famous "Hawaii" demo for the PET 2001 computer (upgrade rom) by Ken Morley. It appeared on Cursor tape magazine #15.
For complete collection (1978-) see:
https://www.zimmers.net/anonftp/pub/cbm/magazines/cursor/index.html
I posted this because I saw the TRS80 "Dancing Demon" demo here, but not this one. Cursor might be viewed as the first widespread "scene" type tape/disk magazine. Each issue had a "cover" program, with a simple m/c or basic demo style effect.
Anyway what do you think was the first "scene" demo/prod/magazine? - isokadded on the 2025-05-14 15:27:36
- game TRS-80/CoCo/Dragon Dancing Demon by Leo Christopherson [web] & Radio Shack [web]
- Remember this from the time, coolest thing ever on TRS80.
But First ever demo? There were earlier ones, ie Try PET cursor tape magazine, 1978-, each issue had a demo effect opening screen.
Also "Hawaii" from Cursor #15.

- 128b Linux MS-Dos This is the (one dimensional) Life!
- yes, inevitable! This one does compile down to 57b if using mod 4 and no user keys, but the results are less interesting. I thought it important that the user could step through a wide range of different effects.
After writing it I realized I had done it differently from the normal 1d method, in fact the 5 colours are 0-255 vga index, which are added and THEN made MOD 5. This makes the colours more varied, and I think changes the maths and makes the effects more interesting.
More experiments needed.
Thanks for the links, useful.. - isokadded on the 2025-05-09 14:32:45
