 Right. I believe what also distinguished most PS/1s was the "stub"
(shell) built into the ROM. This contained a Quad-screen interface
with 4 choices of programs- MSWorks, Prodigy, DOS, and another
I can't remember. The "stub" could be bypassed and a regular
system installed to replace it. I've got a 2011 ( the monitor section
contained the PSU so the bottom section is useless without it)
 The 2021 was similiar. I also have a 2123 and 2133 which had
separate monitors. I believe the 20xx models were 286 while the
21xx could be 386 or 486. It's interesting to note that there were
specific French-Canadian submodels.
