I have come across an Apple IIe with a True Data Corporation card in it.
 S/N 0267 model 350405901 rev a
 cable out to 25pin female D
 4 dip switches
 Sure would like to know what it is for! :)  And, of course, would love to find the dip
switch info. 
Any large (>24 pin) chips on the board other than EPROMs? If so, what are
their numbers?
