The ibm 5161 expansion box was designed for use with
the ibm pc.
the pc had fewer slots then the later released pc xt
and it's power supply was too small to handle a hard
drive.
the exp box added a hard drive to the system and
provided extra card slots ( i think the box also had
additional bios or came with an extra fixed disk rom
chip that went into the pc).
the card that connects to the ribbon cables that come
from the exp box goes into one of the pc's card slots.
i cannot remember if it is slot specific or if it can
go into any slot - there is a plate on the pc's back
that removes to allow the ribbon cables to exit the
case.
a local retired ibm ce had asked me years ago if i had
ever seen one - as he was looking for one at the time.
i was told that the expansion box was a little rare
because, shortly after the pc was released that pc xt
was released .
the pc xt has a large enough power supply to support
a hard drive as well as the bios to operate one and it
has eight card slots.

Hi collecting folks,
A surprise consignment arrived for me this morning -
an IBM 5150 in not
bad
condition complete with keyboard/monitor and a 5161
expansion box,
spare
expansion card and 2 extender cables.....reading the
classiccmp
archives
back to 1998 makes me think I should be impressed
since the 5161 isn't
that
common? It all apparently works but I won't be able to
set it up fully
till
tomorrow. Not much info about it on the web either,
though because 5161
is
obviously bits of a phone number there's a very high
signal to noise
ratio.....
cheers
