  Pair-production of heavy top quarks at the Tevatron Collider is significantly
enhanced by the color--octet technipion, $\eta_T$, occurring in multiscale
models of walking technicolor. We discuss $\bar tt$ rates for $m_t = 170$ GeV
and $M_{\eta_T} = 400-500$ GeV. Multiscale models also have color--octet
technirho states in the mass range 200-600 GeV that appear as resonances in
dijet production and technipion pair--production.
