I just acquired a DG Eclipse S/230 in semi-decent condition. It's mostly complete with some fun peripherals in a gigantic rack. It'll be fun to get it going, but it's going to be a challenge -- the machine has been scavenged from here and there, I'm missing basic TTY I/O and controllers for the 8" floppy drive (and probably other things, too). Going over the boards, there's an IC on the "CPU 1" board that was somehow forcibly ripped from the PCB -- it looks like someone started clipping it off, then said "screw it" and yanked the thing off with pliers, leaving much of the leads leading up to the IC die. The PCB is undamaged, but I don't know what the IC is supposed to be. I suspect, based on what's surrounding it, that it's an SN74172J. The IC is located at position X3 (approximately, it covers more real estate than that). Anyone have a CPU 1 board from an S/230 they can check for me? There isn't much in the way of schematics for this that I can find... Thanks! Josh
