Hello Everyone I have an antique that is no longer supported by AB, A PLC2( mini 2/16), which I just pruchased a hand held programmer for. I plugged in the unit (with new batteries installed) and turned on my PLC2. Like always, my rack lit up, all cards working fine. The 1770-TB has no display and is apparently dead, does it require a separate power supply in addition to the battery pack and what is supplied by the rack? I figured that since the AI only works on win98 and before that the T-11 would be a viable alternative. Does anyone have literature for the unit? or better yet advise(constructive would be appreciated). Thanks for the help Jaye
