Probably pushing your definition here, but...
Veritas Technologies released a DPO (dual processor option) 8088 board for the TRS-80 Model II. It was a complete 8088 computer on a single board that used the Z80 portion of the Model II for I/O. It ran CP/M-86 according to reviews and was intended to run MS-DOS. But few if any of the boards made it into the marketplace before it was dropped. Apparently they could not get it to work with the Model 12 redesign.
The MicroMerlin was an 8088 expansion device for the smaller TRS-80s which actually was a viable product for awhile.
