I need a bit of information about the main computers on the space shuttle. A small wager rides in the balance. 1. how many? 2. what kind? 3. how old? 4. more powerful than a PC/XT?

I am sure someone over in sci.space.shuttle would have a better answer, but
this is what I remember. (Someone is sure to correct me if I am wrong :-)

5 computers (4 IBM AP101's and one Raytheon?? one); about 1972 technology,
96K core, tape drive (to page different software for various phases of the
mission. Definitely a lot less powerful (and larger) than a PC, but which
would *you* stake your life on? They are planning an upgrade to 256K of
semiconductor RAM in the near future.
Lately, they have been taking up a GRiD 386 laptop for various housekeeping
chores on board...
