Volex TTX2000 S Teletext adapter

I've finally got around to writing an article about the TTX2000 S teletext adapter for the ZX Spectrum that I bought in 2017, describing how the hardware works and a (currently incomplete) commented disassembly of the ROM.

If anyone has a TTX 2000 in their collection I would be very interested in getting internal photographs, and dumps of any different ROM versions too.
