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.

Re: Hello!

Welcome! :D It sounds like you need to get yourself another Electron. ;) I recently pulled my Beeb down from the loft, and obviously the PSU exploded. My 4 year old son (who was having fun playing games on the Beeb at the time) thought this was absolutely brilliant. He's a big fan of Daddy's old com...

Re: AP6 rom incompatibility with Codename Droid

It would be interesting to know if there are problems with Codename Droid, or any other games for that matter, when running from the MGC with an AP6 present. Indeed, it would be useful to know about any incompatibilities that people have discovered.

Re: Adventure Soft / Scott Adams recommendations please

I wouldn't be at all surprised if there was some kind of screen reader for the BBC Micro. The BBC Micro was massive in education and alternative access in the UK much like the Apple II was in the USA. All kinds of forgotten stuff was made for it. It occurred to me that one way that a screen reader ...

Could that be fixed in the python code, by scaling/padding? Yes, I'll pad it, I think.

Dave, I've sent you a pull request for your Atomulator repository on GitHub.

I also recorded a video and uploaded it to YouTube but it seems that 512 x 384 is a video size that causes problems as, even after a few minutes, it's still not been processed. :lol:

It's not usual on the Electron version, though I believe I have seen this sort of behaviour before when experimenting with lots of collectable objects, like grenades.
