First, I'll say that it probably isn't worth your while, if it takes a 
month to process 100 work units.

What I'd do is keep two clients on the floppy - one Windows, one DOS. 
Run the windows one to fetch/flush to the buffers.

Of course, floppies may be a bit slow. You should be able to set it to 
store buffer files in A:\ or so (probably by setting the path to the 
files). Then have a windows client configured to also read buffers from 
A:\, and you can move the floppy, fetch/flush, and move the floppy 
back. Hopefully the cruncher will be in the middle of a block and not 
care that the disk was removed. If there's no monitor connected, you 
may be able to get away with typing 'r' (retry) after reinserting the 
floppy, just in case.

Lastly, there's the -import option which you can use to import blocks 
from buffer files, but sadly no -export, so you'd have to move buffer 
files around somewhat (specifically buff-in from the windows client to 
the floppy, and buff-out from the DOS client to the floppy), which 
would involve stopping the cruncher.

Alternatively, don't do anything, and use the money you save on your 
electricity bill to buy a new computer.
