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 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.

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.

I hadn't noticed that about Estra. Games that load over the screen memory obviously take more time. I think later games such as Bonecruncher did that.

Re: The slowest-loading tape games

I'm looking for an Oric tape with 2400 baud to have a look at. MSX also has 2400 baud. They are both quite similar to Acorn tapes.

The blocks could be longer as well as the gaps being shorter.

I'm not greatly into disks. Is there a utility that transfers a disk to UEF for the PC? I'm only expecting ordinary files to transfer. The UEF file would have a typical baud rate and carrier tone lengths of course.
