You CAN continue programming in BBC Basic even if you are running XP or Vista on a modern PC. Richard Russell, who wrote the original version of BBC Basic for the BBC Master's second processor has written 'BBC Basic for Windows'. A version designed specifically for Windows based machines. It is as powerful as the original and makes extensive use of the Windows system as well. It takes some beating!

As a BBC Micro fan (currently own three plus accessories, books, etc.), this is a great read. It's a shame that today's computers are so complex and leave no scope for the sort of enjoyment that could be had from a BBC. Thanks for posting this article! Excellent!

Was we robbed or what? I am a sad old fool too, but nostalgic and I only wish I could continue programming in BBC Basic

I LOVE the good old Beeb and still fool around on my punch-packing Master Turbo on a regular basis. If only to play Elite ;) Those were the days. As for Neil's project; I'm currently dreaming up a design for a PCB that will hold up to 8 Commodore 6581 SID chips (only got 4 at the moment, maybe 5 if I wreck my last complete C64) and memory-map them on the Beeb via the incredible 1MHz bus. Won't be needing MIDI then I reckon. Can't wait to start coding the lot and make unbelievable sounds. And as for Graham's thoughts; sounds to me like one hell of a machine. A 3GHz 6502 ? Wow ! Maybe it should be an ARM3 though, my other great love, because ARM assembly is simply the best ever. Still can't believe we have to do with those Penthingies or whatever either.

And the 6502 was my favourite processor, in fact the 6845 is at the heart of the CGA in the early graphics cards for IBM pc's which is why I am here. One day we will reach a limit of how much info we can store and how fast we can access it (a memory module 1 mile long will have access time issues) don't laugh have you seen how big applications are becoming !!! going back to zx81 and BBC micro days is the only way forward, everyone should learn assembly language, binary arithmatic and logic. Imagine a BBC micro with 10 gig of RAM and 100 Gig hardrive and a 3 GHz 6502 ? oooh! and no bloody USB just nice TTL pins everywhere !!!!! Alas! that is too much power for us humans to handle so we make do with IBM pc's instead. Oh my GoD, They were the best days ever.

I'm designing a MIDI interface for its user port. So why am I looking at a description of the BBC Micro? Because I want to know if the MIDI interface will be hardware compatible with the BBC Micro too (perhaps with a different connector!) Why am I building a MIDI interface for twenty five year old hardware? Because I think it is cool that writing a device driver is as simple as a couple of dozen lines of assembly language - rather different to writing a device driver for a USB-based MIDI interface on my Mac or a PC. Plus 8-bit Commodore machines have interesting on-board audio hardware that I want to utilise as a musical instrument.
