Re: ABug Scotland (working title) Meeting 4th April 2.00pm

We'll have to see how the second virtual ABUG goes, but I'd be wary of having too many people in one conference call. So, one or two special guests might be fine, but a free for all might be unworkable. There's also a question of how it's arranged: is it a circle with everyone equal, or a panel, or...

... I’ve tried reformatting the MICRO SD but still get the same error. Any help or advice would be greatly appreciated. It’s a Model B that I have. Have included pic my ROM layout below.
If you reformatted the MicroSD card (FAT32), did you copy the Beeb.MMB File back onto it?

Re: Adding a Raspberry Pi Second Processor running PiTubeDirect using KenLowe's Level-Shifter Interface

OK, Ctrl-Break gets me a > Prompt. Am I correct that the *FX 151,230,n is only activated after the Ctrl-Break? That's not quite correct. The Pi can't tell whether Ctrl is pressed or not, so it will switch to the new Co Pro regardless of the break type. However, the Beeb OS only transfers the langau...

When the Beeb Boots, it shows just a flashing Cursor and needs a Break to display the normal startup messages. Question 1: Should this be a Ctrl-Break (which Clears Function Key Settings) or is just a Break OK? Either should be fine. (It's a shame this case now hangs on a Model B on power up. It's ...

Re: New Raspberry Pi to 1MHz bus interface

The Tube level shifter was never really meant to be a dedicated For Sale item, as there are several other vendors out there who already sell them. It was primarily built for those who needed to get power to the 1MHz level shifter from the tube port whilst running PiTubeDirect at the same time. As s...

I have seen threads relating to the install on B's order of chips but not sure what IC to stick the MMC into.
The MMC ROM should be "above" the DFS in the order. I am not familiar with the B+ socket positions but a *Help will tell you what you have and the heirarchy.
