Nope.  The PC-1 had an 8088 as well, and was limited to 64K on the
motherboard (using 16K chips).	It also had only five expansion slots
compared to the eight on the PC-2, which could hold 256K on the
motherboard (though by adding one chip and replacing another, you could
get it to hold 640K on the motherboard).

BTW, even the newest PS/2s still have the identical BASIC interpreter
in ROM (copyright 1981).  Has something to do with the fact that IBM's
BASIC.COM and BASICA.COM make calls to absolute addresses in the BASIC
ROM....
