It has four 74ls367 93 state buffers), four 74ls243
(Quad 3state bus
transeiver) and one 74ls00 (Quad 2 input NAND) that are in sockets. Any
idea why they'd be socketed but the rest aren't?
Typically manf. socketed chips they found failed more frequently - or chips
that where the most available version could be used - i.e., substitute a
74s00 or 7400 for a 74ls00, etc.
