 There was a PS2/8530 XT and a PS2/8530 AT. I have both machines.

 To my mind the PS/1's all had a 2xxx-xxx designation. I have a 2011
which is a 286. The monitor unit contains the PSU. It also had a built-in
2400 modem. The 2021 is virtually identical but IIRC had more memory.
 I also have a 2123 and a 2133 which were 386's.

 I have 5 other PS/2 MCAs , my favorite being the 8580 which introduced
the PS/2 line, MCA, and VGA . A full tower built like a tank which could be
dissassembled in a minute with a dime. It cost $10,000. bare.
