Is there documentation for the position of the line and frame blanking and sync pulses for the TC2048 computer?

It's probably available somewhere in the Fuse emulator docs. I know Fred did extensive testing on real hardware to ensure accuracy. But this app is just to test that all three video modes are working in each frame buffer with ULAplus palettes enabled in 8x8 attribute and 8x1 attribute mode. Currently Retro Virtual Machine does not display the video correctly.

The four frame buffers are offset $0000 and $2000 in HOME banks 5 and 7. The three video modes are 8x8 attributes (normal Spectrum), 8x1 attributes (Timex color) and mono 512x192 pixels (Timex hi-res). There is no HOME bank 7 on the TC2048. However, as the files are all loaded at $C000 that wouldn't matter, except that the TC2048 has no ULAplus and can't run SE Basic 4.2.
