Why too obscure ?
The Philips P851 mini also uses a 8X300 / 8X330 combo for floppy & HD controller.
Picture of this controller and dumps of proms are on :
If there is a chance to have a good pic of the P851 frontpanel I would appriciate it !
Too bad the 851 CPU uses ASIC for datapaths & control logic, so I cannot get this system up and running since it misses the control one.
