And of course, treat yourself to the PM5534 manual: https://github.com/inaxeon/PTV_Preservation/blob/main/PM5534/Docs/Manual.pdf Stan has given permission for it to be shared, on the condition it is never sold. Well I don't think we're going to be doing that ;-) And the PM5570 manual can be viewed here: https://github.com/inaxeon/PTV_Preservation/tree/main/PM5570
