Interesting. HP made ISA card versions of early
(or actually, pre-)
HP9000-300 that were designated as "Basic Language Processors", hosting a
68000 and having GPIB I/O. Interesting beasts. I believe that they were
able to take control of the ISA bus for at least some functions; they were
fast for their time, and it was easy to share GPIB-acquired data with the
MSDOS world.
The HP 82324A coprocessor card wasn't an ISA bus master card.
Software
running on the host PC implemented some of the I/O interface. When
software on the coprocessor card made some I/O accesses the
coprocessor card could be frozen while software running on the host PC
completed the I/O access.

This article describes the second and faster version of the card based
on the 68030.
