Hi,
I said I had a Blizz 4 but it turns out its an 030 Mk4 with an IV SCSI system. All jolly confusing and looking at pics it seems more like an 030 with all the trimmings (apart from an empty plug above the Motorolla CPU which I'm not sure what it's for). Again, apologies for this and I hope nobody is too annoyed with me. :-(
