Nope, it's CMOS clock plus battery RAM, Motorola MC146818A clone. |

I putting my bet as of CACHE chip on position "U2" left bottom corner of memory slots below JP1 and above first ISA slot, can barely reed numbering but its TOSHIBA TC.........
p.s. most of 74/244 series dips are latches ("relays") of some sort
