Yep. Found those. Full of SRAM, not DRAM, astonishingly enough.

Three. I have three 1MB modules. Didn't know there were 4MB modules.
I'm sure I'll never run across any. For DOS usage, 3.6MB is OK. This
one has Windows 3.0 on it, but I don't need it for what I'm doing.

Mine has the bog-standard 40MB Connor drive (type 22). Would love to
find a set of replacement ROMs for this so I could use oddball drives,
but for now, I'm stuck with what I've got.

P.S. - I got impatient/bored, so I carved the top of the DS1287 off,
bored out the battery and soldered on some wires to a lithium battery
holder. Not sure I can put the lid back on (used a low-profile socket,
but it's awfully close to the aluminum drive tray/RF sheild), but for
now, I have successfully loaded high-density floppies into it and
am staring at the up600 application menu!
