Does one hook their hard disk into your box?

Does it require software or is it a total hardware device? (hope, hope)!

I thought the 256k and 1Meg chips had different pin-outs and sizes!  Is
this true?  If so, how are you getting around these physical differences?

If this is cheap enough, it could become a great plus for UNIX lovers.
Having a completely external ram disk (i.e. it doesn't take up internal
ram) is perfect for swap space, /tmp, and /bin.  Something like this
could help turn an ST into a (diskless, er, ram disk) workstation. 
Now if I only had a TT (file server), a nice big *HIGH HI-RES* mono
screen, and X windows, and Sun *might* have some low end competition.

What kind of work has been done on Ethernet iterfaces to an ST.  My
ST could sure use an expansion bus.
