Re: Yarrb - redesigned

Hi Dave and Roland. I changed over the position of the jumper to the left, and it booted up fine and I tested the Asteroid program and others. The YARRB was installed as a new install, with my own IC’s inserted, and the noise killer. The Asteroids game worked ok, but did crash a couple of times with...

Re: Yarrb - redesigned

Hi Hoglet,

It does start with the beep at the end, and your program triggers it too.

It sounds like a machine gun, continuous single bleeps.

Re: Yarrb - redesigned

Hi Chris, I remade your mod again, this time I left out pin 10 on ic44 as directed. The problem is still there when I killed in Asteroids, but other newer games, like chuckle egg, run ok . I wonder if everyone has the same problem with this game on hoglets menu A. Could someone check this game for m...

Hi Dave, Thanks for your input, I suppose I can reflow the connections on the 6847, but that’s about it. I’ll leave out the noise killer as you suggest, I certainly notice the difference in screen clarity with it out. In your posts regarding the hdmi cable being cut at core 4 ( I think) to stop cros...

Re: Yarrb - redesigned

Hi Folks,

I am scrolling through the menu trying random programs, it certainly seems a bit more stable, it would normally have crashed starting programs by now....15 minutes up.

There is more noise on screen as expected, without the noise killer.

Re: MMFS SD Card on the BBC B Printer Port?

Hi Jason,

I’ve not tried any of these on a master, I didn’t get round to it at the time as something else came up.

As you don’t have a master, I’m happy to test it out under your instructions as required...but I’m no expert.

Hi chrisn,

Glad to hear you got yours working, where did you get the info on the commands...
Quote.
[Edit] The board is working fine at 1MHz and 2MHz (using ?#BFFE=70), but if I select 4MHz (?#BFFE=38) the Atom hangs.
I don’t see the in the Manual.
