Raindirk console modules

[bramley]

Looking for any drawings or info on late 70's Raindirk broadcast input modules, series 400.

The boards are designated " R1298A " . The cream & green knobs are not original.
thanks!

I now have a full input module schematic, if anyone comes across this while searching for info on the Raindirk series 400 please PM me, I'll get it to you.
