Re: Raspberry Pi as the successor of BBC Micro

…both the beeb and spectrum have the OS built in. None of the home computers had an O/S. They booted into immediate mode for a BASIC interpreter, and sat in a tight processor loop waiting for input. There was no user management, no multitasking, no memory management, no file or network management. ...

Re: Raspberry Pi as the successor of BBC Micro

I'm 37 so I remember the BBC micro appearing in the classroom all those years ago. The point I'd like to make is that when I first booted my BBC/ZX spectrum I was immediately confronted with a ready to use programming interface. Getting the PI to the same stage requires considerably more effort, kn...

Re: SALE: Many unused RPi Model B in UK

Does not instill buying confidence when perfectly reasonable questions about the sale are asked but the replies back are very cagey and will only communicate via PM if direct answers are required. This one has 'walk away' all over it.

Re: Raspberry Pi as the successor of BBC Micro

that really does not make much sense both can boot to the command line in 30secs and you can program right away the raspberry pi has a much bigger library of programming languages than the Beeb ever had and higher resolution and more memory and faster Your just dismissing it out off hand without RE...

Re: Raspberry Pi as the successor of BBC Micro

What would be interesting to see is a match up between the BBC model B and the Pi. Both aimed and promoted towards the education establishment, both aimed at being very simplistic in their setup and running. As some have pointed out, the Pi is not exactly the easiest thing to start programming with ...

Re: Send mass texts to everyone near your pi

What the #OP plans looks to be a clever advertising/marketing gimmick. If you come within X distance of his building, it sends out and automatic message to the persons phone. If this was legal i think many of the big companies would have implemented something by now. For example, you walk nearby a M...

Re: Help!!! Raspberry Pi B+ Will not boot!

I notice in the boot screen it is detecting a USB hub. I think the Pi is drawing too much power and the 1A apple supply you are using is not powerful enough so it reboots at that point. You need a 2A power supply.

Re: Failed RoHS for plastic parts in USB

In all seriousness this needs to be investigated by the Foundation. If the manufacturers are using non-compliant RoHS parts but passing off the units as RoHS compliant this is a major problem. RoHS compliant parts are more expensive and manufacturers would use non-compliant parts to reduce costs but...

Some things you can glean from the graph: There are around 500,000 256MB Pi model B's There are approx 100,000 of the "rare" 256MB rev2 Pi. 15% are Rev1 models (no mounting holes) 20% of Pi are 256MB models (a fair bit more including model A) https://docs.google.com/spreadsheets/d/1zWwpcckDEEVAhNH3...
