That would explain what killed my master!

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?

Jon

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?

(perhaps use different subdomains for the different purposes?)

I have sent a request to ESET to get the site whitelisted again.

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 ;).
