Totally awesome

[@danimationstips]

Amazingly cinematic for high-key monochrome!

[@btarg1]

The coolest one yet! The smoothness is really impressive

[@Foebane72]

It is smooth, yes, but the music is fucked up.

[@SpaceParanoidX]

Awesome

Now port it to the real Teletext graphics machine, the Philips P2000T! How does this fit in RAM btw? You can usually fit around 40-50 pages max.

The BBC Micro had a real Teletext graphics chip.The Philips SAA5050 and that’s what Mode 7 used. This is Mode 7 on a BBC Micro.

@@melanierhianna I know, but it was kind of a side-kick, the machine itself was pretty beefy. Hence the challenge to get it into a Z80 machine with just a SAA5050 and 32kB of RAM.

Don't think this framerate can be achieved on a "common" TV like my old CRT Samsung

[@thepostalteenager2206]

Whats the year of manufacturing?

If you're using an RF modulated PAL / NTSC connection (coax TV areal lead) then 25 / 30 Hz will be the limit. If using the BBC's Composite Video or RGB ports the Motorola 6845 video encoder can to 60 Hz, it's then just a question of what your particular TV / Monitor can support. The GitHub page states the demo is running at 25 fps / hz.
