No, the PS2/m25 and m30 were ISA the PS2/m40 and m50 286 version was MCA,
different bus. it was the m25 and m30 that were the inexpensive XT class
machines eith 3 ISA slots and a thin case (~4"). As XTs go they were
turbo (8mhz) and well made. The rest of the PS2 line was MCA bus (better)
and incompatable at the card/bus level with the then PC world.

Whoops there.
I have model m35 (386sx and slc version do exist) that has ISA slots,
m25 and m30 can either be 8088, 286 or SX. Model 40 used same board
as m35 except more slots and more drive bays. To differeniate:
starting model series based on MCA from ISA is m50 and up.
BTW, all PS/2, many PS/1s, some Aptivas, any IBM machines were good
made quality-wise even case components and circuit boards.
Mind those later PS/1s that has 386 and up. They're much better than
the early PS/1's, few did support parity ram. I know because I have
few of them and read the hardware manuals.
