I believe the TI-66 despite having alpha key legends in programs and LCD and two-three years younger was a BIG step back in speed compared to the 58/59.

Indeed. However, consider TI 66 appeared in 1983 after TI 88’s cancellation. In my opinion TI 66 was meant to compete with HP 11C not to replace TI 58/59. Then in 1986 the TI 95 (note the figures ) came. It had little success although it was a good machine.
