I wasn't suggesting that people want the feature in order to be deceptive. My perspective is that it can be disorientating if you've read an original message then the author went back to change something. If you have a memory that picks up certain turns of phrase or snippets of information that were...

Thanks for posting the link. It's very interesting to read 4am's perspective on copy protection. I wonder if the Scott Adams adventures on Acorn platforms had similar in-game copy protection checks to those mentioned in the interview. I don't think I've ever looked at those games in any detail. Does...

I only tend to "silently" edit if I'm fixing a typo, broken link or attachment. Other than for those reasons (and sometimes even for those), I put a reason for editing in the message because I think that, even if I could get away with a silent edit, I don't like the idea of tampering with a message ...

Liking the animations!

I'd like to be able to feed my changes back into an official repository. I can import mine into a new one under the stardot organisation on GitHub if that sounds good.

myelin, I noticed that you sent me some pull requests. I'll try and get to them early next week.

davidb

Welcome at long last!

Ah, Metal Mickey, also known as Android 0.1 (Atomic Thunderbuster).

The Lass O' Gowrie looks familiar in that video. I wonder why?

Hi there! I was the one who invited you here. :) Feel free to post an introduction in the introduce yourself forum. We like to hear how people got here and what other retro kit they might have. :) Your Electron doesn't sound as bad as I had imagined. It looks like the experts will be giving you some...

davidb

A couple of non-technical questions from me. :) Was the protection on the tape versions (particularly on the Electron) ever shown to be effective at countering "piracy"? I realise that the Beeb scene had lots of users who could crack games to disk and share them that way but there didn't seem to be ...

Welcome from a fellow Electron user.

Sorry to hear about your original Electron, though it seems you have more than made up for losing it in recent years.

In this video, it looks like someone has picked up a copy of Maths 'O' Level Revision II Geometry and Set Theory by Shield Software. Acorn Electron World only lists the first volume, so I wonder if this is in the education archive.

The guy in the video didn't seem too impressed with it.

davidb

Very nice! Thanks for making it available.

Conpressing everything to a spark file (ie /arc) will allow zip files within it and works okay, but it still tries tode-archive any spark directories found within the parent. Disconcertingly, with varying degrees of success. I couldn't understand exactly what the problem was with nested Spark archi...

Welcome!

It would be good to see more demos for the Electron and A3000 since both were machines I grew up with.

davidb

Welcome!

Are you the real Jet Set Willy?

I also suggest that a statement is added to the effect that the text and picture content provided by users to StarDot becomes the copyright of StarDot. This then means that if a user asks for all their posts to be removed, the administrators may not have to remove all of the posts. As removing some...

And to round off for now, here's one that switches screen modes periodically:

Code: Select all

10MODE2
20?&FE00=0
30M%=2
40A%=&18
50B%=0
60REPEAT
70!(&3000+RND(&4FFF))=RND
80?&FE03=A%
90A%=A%+1
100IF A%=&40 A%=&18
110B%=B%+1
120IF B%=256 B%=0:M%=M%+1:?&FE07=(M%AND7)*8
130UNTIL FALSE

Edit: Video on YouTube.

davidb

This can probably be shortened but is a more colourful version of the previous program:

Code: Select all

10MODE5
20VDU23,1,0;0;0;0;
30A%=&18
40REPEAT
50!(&3000+RND(&4FFF))=RND
60?&FE03=A%
70A%=A%+1
80IF A%=&40 A%=&18
90UNTIL FALSE

Edit: Also try MODE 2 instead of MODE 5 for even more colours!

Ah, it turns out I had run some of the previous programs before running this one. Try the next iteration on this theme:

Code: Select all

10FOR A%=8 TO &20
20?&FE03=A%
25!(&1000+(RND AND &7FFF))=RND
30NEXT
40RUN

davidb

One for the Electron. Perhaps someone can convert it to the Beeb:

Code: Select all

10FOR A%=8 TO &20
20?&FE03=A%
30NEXT
40RUN

&FE03 controls the top 6 bits of the screen start address.

It gives you two expansion interfaces for the price of one, especially since a lot of add-ons were made in cartridge form rather than use the bus directly.
