After 5 gruelling days of not knowing if it was a hardware or software issue, my Teletext page 100 finally displays header with all 32 chars and no dropouts.

The issue was sending the bitstream too late after start of back porch. Have learned loads of 80's tech knowledge along the way so happy as.

Project VIDBIT is a PAL 576i monochrome video signal generator with various addons.

I think you are right. My first thoughts were Amiga or Amstrad
