Notes
The difference between WD1006V and WD1003V appears to be the buffer size.
- WD1006V-MM2 - 8K buffer
- WD1003V-MM2 - 2K buffer
There are a pair of link contacts (directly below J5) that set which buffer size the card expects. Switching this link and the RAM chip is likely the only requirement for converting a WD1003 to a WD1006 (or vice versa).
See the https://theretroweb.com/expansioncards/s/western-digital-wd1003v-mm1 page for the version of this card not equipped with a floppy controller.
