Hi ! Could anyone give me the REAL pin assignment of the terminator used on the IBM 5110 / 5120 systems ? Has anyone build such a terminator ? I tried to build one and I'm fed up with getting always the same error : I can obtain the file list (using basic command UTIL DIR,D80 or UTIL DIR,D40) but 5 seconds after giving me the file list, the systems blocks, the promt disappeared and I must restard all... No led is lightning on the pannel...Sometimes I get the 24 or 26 error code (''diskette error...''is only said in my reference manual : what a help !). Very strange diagnostic... Thanks for your help ;-) Fred.
