Re: I think my 6522 in IC69 in my Model B is faulty

Definitely sounds like 6522 to me. I think my carnival requires a user via timer, but my Pacman doesn't if you fancy a blast while waiting for your replacement ;)

Re: Write some BeebASM output to text file

I build the string/file in memory and then save it. This method may not work for you if you are building a .ssd. I build my disc image as a second pass as I computers my game between the two passes. https://stardot.org.uk/forums/viewtopic.php?p=263175#p263175 look from the hex4 macro at the end. I u...

The kids prefer the sega megadrive pads that I use with my own adapters.
I don't suppose you sell those do you? I have a soft spot for Mega Drive controllers.

Re: BBC B+ 64K

I was also going to suggest exercising the palette to see what happens. You would get the effects that you are seeing if you only partially program the palette. Does the flashing stop if you hold break or change the flash periods. There is a thread to a great new website all about the versions of ma...

Re: Excellent New BBC Joystick.

Edit: sorry, I misread the thread and confused the analogue joystick with the digital one! This is about the digital one, but I do have one of the analogue ones but not from this seller. They look to me to be 3D printed, with modern joysticks parts, designed for "zero delay" USB adapters....

Re: Digital to analogue Converter

I'm sure it's not suitable for what you want, but apart from stuff in the music x000, there was a parallel port DAC that was just a resistor ladder + decoupling (?) capacitor.

I can't remember for sure, but the virtual ABUG videos may have something.
The boobip eeprom board has a simple basic program for updating it and the DIY eeprom also has software on here. I don't know about any others.

I had 13 bytes free and managed to rearrange some code to make reducing the difficulty after dying "for free", but stopping the invisible bombs cost all of the 13 bytes. There are still a few bytes in ZP, so another tiny change may be possible! I can't guarantee that the invisible bombs is...

Re: B-Em

Sorry, I don't do git.

It wasn't constantly slow, just some slow frames.

47% of CPU cycles, but it was probably two threads.

I'm not sure how the poll time would help unless it is very infrequent.

Thanks very much for the video. I see the bottom of the shield graphic being left on screen when the mother ship is coming down, I don't know why I haven't seen this, but I suspect it is to do with being char row aligned. The bit of the mothership that gets partially destroyed and then restores itse...

Re: BBC Micro Issue 3 - couple of issues

If you have the board or again, does the socket for the 76489 look like it was added later, has different looking solder?
If so, maybe someone already tried swapping it.
