Hi, I recently made a trade in which I received a KTM-3/80 terminal (thanks Claude W. !) Questions: (1) Does anyone know what the power requirement is? Claude mentioned he tried a 9V AC, 1.5A or 2A power supply - and the terminal produced "garbled" characters on the screen. It was not determined if this was due to an improper power level being supplied - or due to some problem with the terminal itself. (My circuit analyzing skills leave much to be desired.) 2) Upon opening the terminal, at one point someone had added a daughter card. It is of the homespun type, not a commercially sold option. The daughter card has a total of 8 chips on it, which are: N7400A SN74LS393N 74LS04PC SN74LS133N SN74LS02N 74LS04PC It has been so long since I used this terminal - I don't recall if there was some particular feature missing that would have been nice to add. Thanks for any/all info ... Eric F.
