Hi,

Sorry for this. I will send an email to all that has bought the Master version.
It should not kill your master if you don't connect the master's serial port to the Signal converter.
These lines go direct to the Pi.

May I suggest when you update the silk screen you use arrows as RX and TX are meaningless, both pins connect an TX to an RX.

Labels are local - RX is in and TX is out. RX at one end will be connected to TX at the other and vice versa.

I know how. I just find arrows showing the direction of data transfer more useful.

Ha must be a preferences thing, I cursed the max3232 converter board for having arrows instead of RX and TX.

Hello

Ive only just come across this idea of using a Raspberry Pi as a second processor on the Beeb, sounds absolutely fantastic.

Kjell S, I was wondering if the you are still producing/selling the PITUBEDIRECT SIGNALCONVERTER FOR BBC MICRO?

I'm interested in the version for the BBC Micro Model b that sits under the Beeb for the Raspberry Pi Zero.

And if so, how do I purchase one from yourself?

Welcome Jon! Have a look towards the bottom of Kjell's overview page:
http://www.sundby.com/index.php/project/pitubedirect/

In passing, I'll mention a recent development or two by RobC: he's written a PDP-11 and a ZX81 emulator, to run as applications in the ARM Native flavour of the PiTubeDirect. So that's two more ways to enjoy your new second processor!

Hi,

This is probably because the site stores a lot of old 8 bit code.
I maybe need to put the mirrors behind password protections.
Can you bypass the block?

There are some problems with snow effects on some BBC Master's using the internal PiTubeDirect Signal Converter for the Master.
The ones connected to the external tube works fine.
It seem like are different version of chips in the Master causing the problem, but this need to be investigated.
To see if you have this problem run the program below and see if you get the snow effect.

10 MODE 0
20 GCOL 0,129
30 CLG
40 GOTO 40
Will investigate and find a solution for this. There may be more that needs to be fixed.

All people that have bought the Master version and have this problem will get a new card.
Since this is a "hobby" I would just ask to get back the cost of shipping the replacement.
I estimate to have new cards ready some time in January for shipping.

Hope nobody gets any problems with their Masters after this.

Not sure if he has had time to read your question as he’s busy putting the new cards together, which I guess answers your question ;).

Hi yes I want to purchase from his shop but he says to ask for total amount if buying more than 1 board ?

I'll just go ahead and buy 2 boards from his shop and fill out the shipping

If there's any problems I'm sure come back to me ☺

Is there a problem with your order page?
In Edge and Firefox I just get grey circles with white circles spinning inside and am unable to continue.... :cry:

I'm experiencing an issue with the Sundby shop using Chrome.

When I input my details I get the following error message:

SyntaxError: Unexpected token < in JSON at position 0

On the checkout page.

I had the same problem with Windows 10 and Chrome. I emailed Kjell at Sundby who asked me to just sent payment via Paypal.
However, in chrome menu - more tools - clear browsing data, cured the error and allowed me to order through the web interface.

Hi i am having some problems getting my retroPi zero to work with the BBC model B

I have just received the PitubeDirect board from Kjell and with that board in the tube connector under the BBC model B the Computers boots up when switching on but when i connect the raspberry Pi zero board to the PiTubeDirect the BBC won't boot up at all ?

I don't even get a biiirrrbeep and i get a black and white display on the screen ? The raspberry Pi zero is new which i have recently bought with the header pins already soldered on. I have left the jumper on the two pins as it came to me which i presume is to draw power from the BBC to power the raspberry Pi Zero.
Can anyone shed some light on this for me please?

I originally bought the Pi zero to use on my BBC Master but found the PiTubeDirect board does not fit under the tube connector on the BBC Master as there is not enough room to slide the board on to the tube pins ? If i'd known this i would have gone for the external fitting in the first place.

I've messaged the guy on ebay who i have bought the Pi zero from and asked if i can send it back to him for him to test to see if its working ok and if not can i have a replacement. I have no way how to test the Pi zero? I don't have a mini hdmi adapter to hook it up to my monitor. I unzipped the anaconda files to the sd card and was hoping for a plug and play but the BBC won't boot up at all with the Pi Zero connected to the PiTubeDirect SC board ?? The two boards fit only one way so there is no way i have connected them up wrong? Any help or advice is much appreciated :)

Have i got the right files need in the root of the sd card for the Pi zero ?

I have unzipped all the files from the anaconda to the root of the sd card but am wondering do i need all of them or do i just need the setting for Pi zero only ???

a quick update i have connected the rasperberry Pi zero to the PiTubeDirect board and when switching on the BBC i don't get a beeerbeep and all i get is a black screen but as soon as i press the ctrl and break the BBC boots with a beep sound to the normal screen BBC Computer 32K Acorn 1770 DFS
But if i type the *FX 151,230,0 to activate the 6502 nothing happens? even if i press ctrl and break nothing happens there is nothing showing that the coprocessor is there at all ?

Do you think the Pi is dead or will i need to download and unzip a more uptodate files to the root of the sd card?
