That machine would have the IBM BIOS upgrade in it--IIRC, the upgrade allowed
640K RAM and XT 10 or 20 MB disks (I once knew a guy who had tubes and tubes of
the originals back when they were worth something--probably a multi-millionaire
by now). It probably also has an upgraded PS as (again, IIRC) the original was
only 63 watts--not enough if the slots were maxed out and a hard disk was added
to the mix. Wow, what a power-user box that would have been in its day.
