I upgraded my SH204 to 100MB more than a year ago. I replaced the
Adaptec 4000A controller by a 4070 RLL controller, removed the Tandon
TM262 20MB MFM disk (and sold it), and put in two Seagate ST157R 50MB
RLL disks. This all fits just about into the SH204 case. And I didn't
encounter any problems with this setup or the power supply so far. The
only problem I had were quite some bad blocks on one of the disks, but
that's a whole different story ...
