I=B9ve got one.  It came with a weird genlock system and a Sony Laserdisc
player (not Domesday, obviously).  Also has some kind of cartridge drive
that I=B9ve never seen before (definitely beeb specific =AD it has a beige meta
l
case).  I=B9ll dig it out of the loft for piccies / details if anyone=B9s
interested.
