The S/370 channel emulator cards (MCA) will work with the P/370, but not
with the AT/XT/370 for obvious reasons.  There was an IO boardset sold for
these (ISA) but they do not do a full channel implementation.

You also cannot treat the onboard DASD (32MB "minidisks") as being channel
attached, VM/PC did not emulate that far down.
