The answer is: no, you can't.

I found a feature list for the MVME147 on the web at
<http://www.mcg.mot.com/cfm/templates/article.cfm?PageID=1095>. It
confirmed what thought I remembered from the Motorola site; no PCMCIA,
no IDE/ATAPI. As a matter of fact neither of these technologies
existed yet when the board was being designed in the mid-1980s.

(The article I found is kind of interesting. It's a dissection of the
MVME147's design and history...narrated in first person.)

In any case, if this *had* been a problem, the right fix IMO would have
been to split the SCSI symbol into SCSI and SCSI_DRIVERS and have
constraints that would make SCSI and the presence of any SCSI card
imply SCSI_DRIVERS.

The prestige of government has undoubtedly been lowered considerably
by the Prohibition law. For nothing is more destructive of respect for
the government and the law of the land than passing laws which cannot
be enforced. It is an open secret that the dangerous increase of crime
in this country is closely connected with this.
