Re: Post Edits

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...

Re: Cracking Apple II floppy copy-protection - 4am

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.

Re: Post Edits

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 ...

Re: Which is the canonical Elkulator repository?

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. :)

Re: Emulator setup to make all ROM area writes use bank 15 SWR

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 ...

Maths 'O' Level Revision II Geometry and Set Theory by Shield Software

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. :)

Re: Nested archives in SparkFS

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...

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

Re: Any short type-ins for unattended Beebs?

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

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

Re: Any short type-ins for unattended Beebs?

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

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.
