Re: BBC Master boot
On my Master (and BBC "B"s), SHIFT-2 is double-quote. What is it on yours?
I'll grant that SHIFT-8 and -9 being left and right parentheses, rather than the PC's -9 and -0, feels odd these days.

Re: BBC Master boot
I took no special precautions with the ROM cartridges, and while they won't have been exposed to bright sunlight in my possession, they haven't been stored in total darkness either. I obviously have no idea how they were stored before I got them, so I would assume the worst. Could you get them reflashed?

Re: BBC Master boot
Sorry, I got that wrong! I am used to shift 2 being an at sign, not a quotation mark. Still, it isn't like I'll be doing much coding or anything on the BBC so I think I'll cope
I am sure I could organise something if required - learning to use a programmer probably wouldn't be a bad thing with the other less common vintage hardware I have kicking around. I am just not sure what should be on them - if they were a standard thing to have or not, and what those other ROMs could be. |

Re: BBC Master boot
Did you remember a series diode? The original cells were rechargeable, so are trickle-charged when the machine is on.
Most sources recommend including a series resistor as well (I use 150 ohms), but I'm not sure how necessary that really is. I usually fit both of these in the unused space of a 4AA battery holder. |

Re: BBC Master boot
The ROMs normally held an application such as a word processor or a game (I vaguely remember that Ramrod was a game). One common ROM was a VT100 terminal emulator.
Lots of Beebs in schools didn't have floppy drives and did everything with ROM cartridges. |

Re: BBC Master boot
That's good I couldn't see it in the photo, but looking again, I'm guessing they're inside some black sleeving that I think I can see if I look at the monitor at the right angle
