Hi, sorry, I’m asking what option I need to select in PayPal, not how you send it.

One option you get charged the PayPal fees, the other option I do.
Sorry for the misunderstanding.
I would appreciate if you send it as a gift.
If not they take 3% of the money.

Re: PiTubeDirect signalconverter for BBC Micro

It will be fine. My master has 2 co pros powered by master (internal and external).a Beebsid, gosdc, 2 carts, videonula, Ethernet module, external power to gotek. I did recently put a more powerful psu in my master, but more because I can, not because I needed 2. You can still run a pi 3 b+ off a 1...

I suspect you are using basic IV e.g. A master. To be consistent we using Basic II for all the timinigs.
Hi,

Your are right.
I did use the Master version.
Thanks for clearing that up for me.

Pi3b+ is much faster. Timings from memory for fast 6502 Pi2 slower than pizero Pizero 290MHz Pi3 290MHz Pi3B+ 336MHz I have some more speed increases in the pipeline that take the 3b+ to 340MHz. The original acorn external 6502 copro was 3MHz so 3b+ is over 110 times faster. Other cores see a speed...

Hi Dave,

The resistors are 33 ohm and not 330 as I previously said.
I have tested my master and it does not have this problem.

Re: BBC Master screen interference PiTube direct

Hi, When designing the first version of the master card I had the same problem, but I thought it was noise on the datalines. Because when I added the inline 33ohm resistors on the data lines the noise was gone. I will change the design and make new cards. I will see what we can do with replacing the...

Re: Pi-based Co-Pro on the cheap - 100MHz 6502 for £10? (now 274MHz)

I have done some testing with it today.
It does not seem to load the kernel at all.
There are no out from the debug kernel.
I loaded the old release from October and that works fine.

So it just seem to be a problem recognizing the Pi Zero W at boot.
