I checked on my unit's. They're blue with a biege band about 2 1/2" tall around the top. The name plates have a brushed aluminium finish. The CPU box is a model "ZDS" and it's also marked "1/40- 32K CPU" and "05-6013-01" and is serial number 26. The disk drive unit is marked "05-6013-05" and "1/40- 60K" and is serial number 275. I found a 32 sectored hard sectored disk in one of the drives. It's marked "PTR V7" "DO - T" "1-40" "5-12-82". Joe
