Re: How do you replace the rubber feet on a Master?

I had that problem and got a replacement set from Mark at Retroclinic.

From memory, I peeled off the old feet, cut the base of the new feet to size and then peeled off the sticker and stuck them on.

Re: BBC Elite Which is the best version? Or do they differ?

Tonight I did a comparison of the Master 128 and Tube Elite version. I'm using the download from STH . This appears to be the original version, not the "Pizzasoft" hack that I'd previously seen. I didn't notice much of a difference when I had a quick play of both. The Tube version does seem a bit fa...

Re: Beeb FPGA port to Spectrum Next

Wow, very impressive! I was planning on getting a Spectrum Next when they do the second Kickstarter, and having a Beeb mode gives me an extra reason to want one! Theoretically, would the Next's expansion connector be usable in Beeb mode? Does it carry the signals to facilitate something similar to t...

Re: Remarkable videos recently posted on Youtube

The Retro Hour podcast with an interview with Steve Furber:

The interview starts about 29-30 minutes into the episode. Not a massive amount of new information (especially if you've listened to the recent RetroManCave episode), but still interesting.

The Blitter doesn't do anything with the actual video generation so new modes aren't really possible - though with shadowing in place larger screen modes are possible. Yep, understood. Any "new modes" would ultimately have the output characteristics and limitations of existing screen modes. I was t...
