     Evidently, (from the "Accelerator II" name) you have a Titan Accelerator II
board. Have never owned one these. There seem to be "II" and "IIe" versions of the
board. This info from Mitchell Spector may help with testing:

>>
According the (photocopied) manual that came with my Titan board, switches 1, 2, 3
and 8 are reserved for diagnostics and should always be set to the 'ON' position.
Switches 4 through 7 correspond to slots, and should be set to 'OFF' _only_ if you
have a timing sensitive card or device installed (e.g. disk controller, video
digitizer, etc).

Older/newer revisions of the card may have had switches 1 to 7 correspond to the
internal slots.

     Perhaps an Accelerator II board owner will have some ideas about the chip you
need. Brian Hammack is the IIe board guru; he may be able to help with your II+
board. Good luck with getting it working!
