There were 655/24 machines in IVC 9000 helical, AVR-1 2" Quad  and Bosch-Fernseh BCN 1" type B. In 2" Quad, the AVR-1 was exclusive in that it was the only machine that could handle the bandwidth required.

I was wondering if any body knew of a process to play these back recovering the colour and as many lines as possible and also to record - capture them. I have thought long and hard and the best answer I have is to treat them as 625 25FPS NTSC Colour suffering the loss of some lines, unless you know better. I obviously do not have a 655 line 24P NTSC SPG, but can look at adapting an AVR 2 or VR 2000 system to play back correctly. The question then is what to do with it to record or capture the signal. Has anybody had any experience of working with this system, how to convert a machine to replay it, and how to save it?
