IBM Series/1 update

Well, it seems that my Series/1 is not working right. I plugged it in and turned it on, and everything(CPU, FD, small HD and I/O unit) SEEMS to be working OK. Except that it won't boot. I took all the cards except CPU, FD controller and 4978 terminal I/O cards out and setup the floppy drive as the primary IPL device. Threw in a floppy labeled IPL(unknown if it really is), set the CPU to auto-IPL on primary device, the LED's on the programmer's panel lit up and did a few things and then it freezes(I waited a around 15 minutes before I gave up) with LED's 8, 9, 10, 13 and 15 on. Nothing happens at all, when the Series/1 is powered up the 4978 terminal displays a "=" in the top left corner and does nothing. Right now I'm not sure if the problem is in the CPU or floppy drive(I haven't had time to clean out the floppy drive). Does anyone have any idea what's going wrong or know someone who would know? I think the system was originally setup to IPL from one of it's four 200MB hard drives, which are still up in the garage(and I can't plug it in because of only 1 220v outlet. not good with three racks needing power) along with two tape drives and another 4959 expansion unit. Well, at least it was free... -JR http://members.tripod.com/~jrollins/index.html http://www.geocities.com/Area51/Lair/1681/
