I also did a very crude first attempt to disassemble it. Since the VT52 has a mode bit that control what operation to run it has to be simulated to get it right. You find everything here: http://www.datormuseum.se/home/dec-vt5x I had a plan to run the VT52 with a logic analyzer attached to recover traces of what it is doing for a keypress, UART in, scanline etc. /Mattis > > Best regards, > Lars Brinkhoff >
