WTD: 5.25" DSDD drive & Acorn Master128 keystrip scan/schematic

[Philip Pemberton]

Hi folks,
  I'm after a 5.25" 80-track (preferably 40/80 switchable) DSDD drive,
jumperable for DS0 and 300RPM rotation, suitable for an Acorn Master 128.
  I'm also after a decent-quality scan of the keystrip that came with the
Master 128. A copy of the Master 128 schematic and/or service manuals would
also be rather nice :)

Thanks.
