There are a number of different variants but, that sounds a lot like my /36. Basically, the entire system is one box (box ass tower) with integral HDs, I/O, tape drive (optional), and 8" floppy drive. I think most of the HDs are in the 60-90MB range. All external devices including the console are connected through a twinax cable. IIRC, mine has several (4) coax connectors on the rear panel. I don't recall the terminal type but, I think they are common IBM twinax terminals. I see the terminals on Ebay fairly often. As I recall, they go pretty cheap. Since the HDs are internal and the systems are not likely to be under maintenance, it's not too difficult to find a 36 with the OS still installed. The one I collected came with all the original install disks so passwords weren't an issue. The lack of an available OS has certainly dissuaded me from bothering with any 400 stuff. I messed around with the box when I first got it but, it really didn't seem all that interesting so, I stuck it in the garage. I'm sure a number of other collectors s on this list also have a /36?
