I was thinking about that (answer to Castellen), but I never have seen the SCSI controller module to put another memory simm (sorry to tell that), so I don't know where it goes.
Does anybody have a photo of the blizzard scsi-kit IV mounted?
I mean, if it fits inside perhaps you could install it with the memory at the back side too?
I've found these photo's online showing the SCSI IV Kit mounted:

http://amiga.resource.cx/manual/BlizzardSCSI4.pdfSo basically the SCSI IV Kit fits nicely just under the keyboard of the 1200.
You could install a 128MB double sided simm on the scsi kit, and a single sided one on the Blizzard (if you could find one, then 256MB RAM is possible).
