The PiTube direct module allows almost any vintage 8bit BBC Micro computer to connect to and harness the power of the Raspberry Pi. This allows for all sorts of amazing software to be used with the veteran system
Today Tom installed a custom internal PCB and reuses an old Raspberry Pi A+ board into his preserved BBC Master 128 computer system.

it's a fantastic upgrade. Got myself an internal one a while ago. I have been able to install the BBC version of DOS and virtual Winchester Drive using a Compact Flash interface, all thanks to RetroClinic. The BBC Master has so much potential as a home computer and I still love using the keyboard after all these years :)
Fella, fella - thank you so much. I get that this is 3 years ago - but the simple copy of the files to the SD card - NOWHERE on the Github site, or in the Wiki does it say "simply copy the contents of the release zip file to the sd card" - thank you again!
I must get around to fixing the BBC master system I picked up some years ago. Looking forward to the co-pro software vid.
Nice idea - the only thing I would suggest is putting the Pi, not the BBC. That way, you original stickers are preserved from adhesive, etc.
My Sunby PTD fits just fine in the external tube socket on my Master 128
that'll be the later revision board.
Its nice to know the external boards now fit both systems
Thank you very much for this video. I made everything as you said and it is working (BBC Master 128, with SD card and PI Tube internally). Now, there should be some HowTo, for example, how to move between disk images, list program, start with chain or load or whatever. Some link for self-learn? I also have SDcard and it doesn't work with tube?
I also don't understand why does: *DIN 45 followed by *TUBEELT starts Elite? Is it Elite on SDcard on image 45 or something else? Is that Elite for 2nd CPU on Master BBC or what? Some help or some links to the really good explanations of FX,DIN,CHAIN commands in order to use this goood machine would be really, really helpful. Currently with only Quick HowTos... I can't enjoy the fully potential :(
Hi .... yeah the MMC interface command set is a little lacking at best, and even im not an expert in it! Although it works well, it seems to assume users are fully up to speed with the commands and many... myself included, are not.
But basically
*CARD followed by ctl+break hard resets the machine into MMC card mode.
*DIN selects the disc image to be mounted eg *DIN0
*DBOOT executes the !BOOT file if present on the disc image eg *DBOOT0
CHAIN loads and runs a BASIC program file
*FX are OS calls for special functions most of which are listed in the BBC Micro manual.
The MMC games menu (*DBOOT0) does not work with the TUBE activated
As for the elite build on DISC 45 I have no idea without checking and assuming your using a stock MMC image. The Co-Pro version of wont boot if a second 6502 is not present (Pi Tube Direct)
There are many other functions which might be worth making a video on some work and others less so.
@@WiFiSheep THANK YOU!!! Hooray! This really, really helps :)
I have one myself and it's great fun playing with CP/M and writing ARM code. I sped up a suitable numeric intensive piece of code by at least a thousand times.
By the way - noticing the upped professionalism of the video :-)
Nice upgrade, although I would like to rip the old beeb motherboard out and replace with Raspberry pi with a hat which provides all the I/O the BBC micro had then run BBC emulation software which uses the hardware. That could run many times faster than the BBC micro with a fraction of the power consumption and support much higher resolutions and colour depth.
no!!!!
Just run RISC OS on the Raspberry Pi. A Risc PC/Archimedes was essentially the "better BBC Micro" anyway.
That's a terrible soldering technique! Instead of using the hot iron to transfer molten solder to the work, simply use the iron to heat up the work and then apply the solder wire directly. That way you don't boil away the flux that's already supplied inside the solder wire (like the lettering in Blackpool rock) and make a lot of smoke. If you do that there's absolutely no need to add any additional flux.
Very interesting... thank you for the suggestion
