Hi, we've cleaned and powered up our TI 960B at our museum, it seems to be working fine. I've entered a small test program to test the basic parts: 1000 7007 0000 NOP 1002 7007 0000 NOP 1004 7082 1000 B @1000 Both single step and run mode work. But that's all we are able to do at the moment because there is no documentation available for the 960B. The machine (from 1975) has 8k of MOS memory, and only few CRU interfaces, one TT/EIA (TT), one data interface (DI) (I think it's a digital I/O board) and one timer interface (TI). So we need at least the programmer's guides for the TT and DI, maybe the service manuals for the entire machine. Is there a chance to find them somewhere? Christian
