The BBC Micro turns 30

Ironworks11

Pre-production?

The first production machines used a 'linear' power supply with conventional transformer and regulators which did get quite hot. We quickly sourced a much better 'switched mode' power supply which ran cooler and could provide the extra power required to run accessories such as floppy disk drives. And yes, the first edition user guides were printed with a simple blue cover. These were replaced with the colorful ring bound manuals a few months after production started.

Yes. Steve wrote the first simulation model of the ARM processor in BBC BASIC and ran it using a second processor.

BBC Micro design team

The picture on page 3 is actually of the Acorn Atom team taken in 1980. I'm not aware of any pictures of everybody who worked on the BBC Micro, but their names are all listed inside the MOS ROM as follows: David Allen, Bob Austin, Ram Banerjee, Paul Bond, Allen Boothroyd, Cambridge, Cleartone, John Coll, John Cox, Andy Cripps, Chris Curry, 6502 designers, Jeremy Dion, Tim Dobson, Joe Dunn, Paul Farrell, Ferranti, Steve Furber, Jon Gibbons, Andrew Gordon, Lawrence Hardwick, Dylan Harris, Hermann Hauser, Hitachi, Andy Hopper, ICL, Martin Jackson, Brian Jones, Chris Jordan, David King, David Kitson, Paul Kriwaczek, Computer Laboratory, Peter Miller, Arthur Norman, Glyn Phillips, Mike Prees, John Radcliffe, Wilberforce Road, Peter Robinson, Richard Russell, Kim Spence-Jones, Graham Tebby, Jon Thackray, Chris Turner, Adrian Warner, Sophie Wilson, Alan Wright.

This list includes key contributors from the BBC and also credits other individuals and organisations who worked with us throughout 1981.

On the pricing: There was some escalation of cost as we included all the features that were determined to be necessary but this was largely offset by purchasing efficiencies as manufacturing volume increased. One major reason for the price increase was a change in Acorn's business model from direct mail order sales to selling through distributors and dealers. This was necessary to give the machine the market penetration and customer support it required but the price had to be increased to provide an adequate margin structure in the sales channel.

Unhappy

Slow and unstable

Sad to say I've just given up with FF after some years. It takes forever to start and latest version 4 unstable - crashes when printing etc.
