Re: Atari joystick on the BBC

It interfaces an Atari joystick to a BBC. It probably connects only one fire button.

Re: Atari joystick on the BBC

You would need a box sized about 7x5x2.5cm. The circuit board fits snug into the box. The board would be the most work.

Re: 5-pin 'domino'-DIN M to DE9 F cable for RS423 port

What baud rates can be used with the BBC serial port? I think the Jafa cartridge for the Electron copied the BBC circuit. How difficult would it be to build now?

Language of keyboard with XP

I don't see any settings for the keyboard language. I have a UK keyboard and a small USB keyboard that is a US one. When I have the small keyboard alone it acts like a UK one. I can only think that the "Regional and Language Options" setting affects it.

Re: Newbie has question

State snapshots do work with BeebEm and many Electron games play identically on it.

I had a copy of the BBC Snapper. Its slower and easier to play because the ghosts get stuck in the tunnel.

Do you mean using Electrem Future? There is menu options for save state and load a tape image which is not well worded. Tape images and state files are both in UEF format.

Re: "Splitting the Atom" reference

What that book calls the header checksum byte is actually a flags byte. I think all bytes are added in a 16 bit store and then the checksum is the lower 8 bits. It probably works most of the time. The Spectrum has a poor checksum that does not use any data from before certain sequences of data.

Re: C++ dynamic component creation

I made my program CSW Viewer have a separate module for the program and another for the UI. Theoretically I could use different compilers for the two. Although its better there is a lot of extra work. I'm considering making the UI be a DLL and the main program an EXE which is the opposite of what it...

Re: C and the const keyword

I would regard using enum as the best choice. I always use it for constants unless they have a decimal point.

Using static like that in C++ is not done anymore. The ints have static storage without that.

I am also looking for one. Isn't the port exactly the same as the BBC one? I know there is a difference in sampling. The Electons Plus 1 does 8 bit samples and the BBC does 16 bit.

Re: BeebSID

XNOR seems to be XOR flipped. Why is it not called NXOR? I tested it with a calculator and 0+0 and 1+1 makes 1, 0+1 makes 0.
