This is a confusion of two distinct projects.

A modified 68000 chassis was microcoded by a team of IBM engineers from
Binghampton, NY.  The resulting processor, together with a vanilla 68000
and a derivative of the Intel floating point unit, went into the XT/370
product which appeared in 1983.

While the above project was in progress, Nick Tredennick (who did microcode
the 68000) had left for IBM Yorktown, NY where the micro-370 project was
launched.  This project used similar design methodology as the 68000 project
itself, but never resulted in a product.
