Hi, Jules.  I used to have two ACWs.  I *may* still have a copy of the
hard drive formatter.  The standard drive was a 20MB Seagate ST225, but
the Acorn firmware will handle up to 2 x 30MB.  The standard floppy was
a double-sided 80-track unit giving 640K under ADFS.

The hard drive controller subsystem consists of a small Acorn-made PCB
which is a 1MHZ-bus to SCSI interface, along with an Adaptec ACB4000
controller (which provides a SCSI to 2 x MFM interface).  There's no
system support for other SCSI devices, though; if you wanted anything
else you'd have to write your own.  Having said that, Digital Services
in Portsmouth (?) did make a tape streamer for the BBC/ACW/Master128.

The memory configuration you have is pretty standard.  AFAIK, boards
with 'hundreds' of DRAMs are the exception, not the norm.
