I suppose this will be an Alphastation 5/400 or 6/400, desktop case with
external greenish grey skins. These use narrow SCSI disks with an
NCR53C800 controller (siop(4) in OpenBSD).

I'm not sure these systems can accomodate more than 8x32MB ECC simms.
Maybe 8x64MB. Probably annoying enough to require the original DEC part
with gold-plated connectors, rather than average x36 FPM simms. I'm not
that sure about that, it's been years since I last used such a system.
I'm only using 21264-based systems those days (as well as a 164LX
system).
