Hi,

    One of my RT's has a rather strange card in it,  It doesn't seem to do 
anything (that I can tell) and I was wondering if anyone out there might
know what it is.
   It is an 8-bit card, and is short.  The metal faceplate has no connectors,
but is stanped with a 7.  At the bottom of the board is something that looks
like a battery, but is soldered on; it is marked 5154
There is a big, socketed IC in the middle marked P/N 59X1003 (c) IBM 1985
There are also 3 socketed chips marked PAL16L8ACN 8528 / IBM 85.
There are also several other chips, and an LED in the upper corner.  Any
leads on what this is/does?

Thanks in advance,
Stephen
