Having never owned a BBC Micro (I had the "trusty" Acorn Electron) I always hankered after MODE 7 and its Teletext capabilities.

This is the first attempt at creating a standalone Teletext server - the intention is a CMM on a stand with a hardware IR remote (Maybe a Windows MCE remote would cover this).

YouTube - Teletext Page

The viewer reads files in TTI format (as used by wxTED by Peter Kwan)
TeeFax
Teletext Art

The only snag I'm having finding a decent resolution that works with 40x25 characters based on an 8x13 font. �

I'm considering moving over to the Bedstead font. �Whilst not a pixel for pixel recreation of the Beeb font, it does look a lot better on the higher resolutions supported by the Maximite.

Feedback welcome, one I've completed the editor (basics done, but implementation and tidying the code for both now) I'll be publishing the code here and on Fruit of the Shed.

Version now incorporating Capsikin's excellent port of the Galax.xyz font

Liking this...

But what is this>>

Specifically the "*EXEC !boot" << am I missing a whole layer of CMM2 goodness?

I'm guessing:
* a history with the BBC micro computer
* OPTION RAM
* an AUTORUN.BAS file that's producing the header
* a file EXEC.BAS either at the root or located via OPTION SEARCH PATH
* a file called "!boot.bas" that is displaying the launcher menu

Am I right ?

Life is so simple when explained so well --- DOH!!!

Thank you - given the depths of the CMM2 I wouldn't have been surprised if I'd missed something though.

Provided you use OPTION RAM all the bits seem to exist in the firmware to write a "better" CMM2 O/S on top of BASIC except for some way to automatically re-launch the "shell" program when another program exits ...

... and some way to prevent that happening when you don't want it to, probably need to distinguish between Ctrl-C to return to BASIC and Ctrl-<SomethingElse> to return to the shell.

Totally, it's a bit of Retro Beeb indulgence. �I'd missed the OPTION RAM will look that up but otherwise, it's an autorun.bas that produces the original page and defines the F12 key to do the same startup except run a file called Exec in the search path that chains !boot.bas in the root.

I've also got that set to run on F12 which is where the Break key used to be. �Shame it can't distinguish between F12 and Ctrl+F12 when launching the script.

If I could get a sample of the Beeb startup that would be in there too!
