Trying to help a new VAX-11/750 owner

A friend of mine at work got the 11/750 recently offered for free in Pittsburg. I don't yet know how it's loaded except for the L0022 mem controller and 14MB of RAM. My friend would _like_ to get a CI750 for it, since he already has an HSJ40 at home. Barring that, he's considering the $$$ for a Unibus SCSI controller. Besides the actual L0009 card, I'm reading that there appears to be an external enclosure to house part of the CI750. My 750s were always a local-disk affairs (UDA50/SI9900/etc). I have no experience with CI hardware and don't know what advice to give him. Can anyone here describe what you need to pull this all together (he already has an SC008 and cables). I'll try to get him on the list... he currently has about a dozen Alpha Servers and is in the process of working backward in time in the DEC world. -ethan
