Today i search PRU08 with google and i have noted that someone has problem. I have a manual for TSX11 and TSX21. I have two TSX21. I have also an PRU08 consolle. I can read program from EPROM with display. I can't write program on my RAM,because it has some problem. I can print program. If someone need some material can ask on Ebay to Plc-City. I need a Ram pc board for my PRU08. :
