The VIP-I/88 ROM chip for the MPF is an IBM CGA graphics module, providing:
'set mode', 'set cursor', 'plot dot', 'write character/attribute', 'read attribute'
Text mode: 80x25 black/white and colour, 40x25 black/white and colour
Graphic mode: 640x200 black/white and colour, 320x200 black/white and colour
Coo! Not sure how you were supposed to interface it to a CGA monitor though. S'pose I've got to open it to find out!
