I'm going to move an old Honeywell DPS6, working. I've in mind to park the heads of the disk ... but how ? The disk unit is from Magnetic Peripherals , model 9448 Internal parts are from CDC , the only code present is BJ7D1-A Anyone know this unit/system ? Thanks Alberto Hah, that brings back memories. The 9448 was code named the Phoenix or cartridge module drive or CMD. Built in Oklahoma City in the early 80's. It's part of the SMD family, sharing the same interface and some of the components, like platters and heads. And used a common Servo Track Writer, the key to their success. For shipping there should be a head locking bar. Lift up the top cover (with power off). On top of the actuator should be a bar with two pins sticking out. There should be a yellow label showing how to twist the bar 90 degrees and it fits into a hole on the carriage and the frame. There was also an instruction sheet stuck inside the top cover with a drawing showing how to install the bar. A lot of the field engineers used to paint the outline of the bar in red for newbies. When new, there was a green card taped to the outer plastic bag with locking and shipping instructions. I don't have any manuals handy - I'm still in Orange County. But if nobody else on the list has any, I'll look on my next trip up to the Bay area - Mother's Day. I think all of my parts are gone, though I did come across a box of heads recently. In the last few months, I've seen the field tester come up several times on eBay. It was called the TB-216. One went for $10 a couple of months ago. These would work on any SMD family drive. Right now there is a Wilson Labs in auction. That also works on any SMD drive, as well as most of the Fujitsu drives. I've seen cartridges on eBay several times, but the idiots open them up to show the platters, thereby hopelessly contaminating them. I used to clean them, but it takes careful patience. The CMD was one of the drives I supported out of OK City for 10 years. I did all the cartridge drives, but mainly the Hawk and Phoenix. I did a long write up on that time recently for an alumni memory book. I should revise it and post it here, provided the list owner doesn't mind 20 pages of ramblings. Incidently, the Lead Design engineer, a media engineer and one of the firmware engineers for the Phoenix work with me here at Western Digital. I shared with them that there still is a Phoenix working somewhere. It delights us all. We spent a lot late nights getting it debugged. Especially contamination issues; removeable media was a Black Art to keep running. Billy
