I also found two Micropolis 1203-I disk drives in the loft. They are 8-inch hard disks, +24V, -12V and +5V power requirements and connected to an ICL "formatter" dated 1989. The formatter has various chips from the 8X300 bit-slice system all over it. They're in Bristol, UK, if anyone wants them. -- John Honniball Email: John.Honniball(a)uwe.ac.uk University of the West of England
