Silly thing's sitting on my desk daring me to power it up, but without a critical bit of code I can't. To operate a 5364 you need a PC attached and running the "Attachment Programs". They act like a control panel for the server -- controlling the whole IPL and diagnostic process. As you may have guessed, I haven't got them. Would anyone on the list have such a set of disks around somewhere? -Colin Eby yea, I have one. you talking about the AT size mainframe with the single floppy drive? I got one about 2 years ago along with the dual floppy 5150 that runs it I guess and a terminal connected via twinax. I managed to IPL the system, but that's it, not knowing how to operate it any further. Mine just uses a single floppy. Is that what's needed?
