Sure thing. Here's a photo of the VT78 on its table over the tabletop RX02 box. You can see the bent metal "rails" in the bottom - the drive box just slides back on those. Quite minimal. http://computermuseum.informatik.uni-stuttgart.de/pics/vt78/vt78.jpg > I’m all for keeping things intact when possible, so I’d also be happy to do a > trade for a rackable RX drive if anybody is interested.

The drive mechs and boards and PSU are quite standard and were available in 2-3 configurations (rackable, DECmate I pedestal, tabletop box, essentially). All the internal drives used Berg-40-to-Berg-40 cables. The external ones used the DB25 arrangement. -ethan

Thanks for the info! I’m all for keeping things intact when possible, so I’d also be happy to do a trade for a rackable RX drive if anybody is interested. Otherwise, would definitely want to pass the box on to any interested collector. --FritzM.

The table-top enclosure has IIRC a small board with a 40-pin Berg and DB25 on it. Systems that came with a DB25 disk drive cable included the early DECmates (VT78 and DECmate I) and the MINC-11. Same pinout everywhere. The disk pedestal for the DECmate I definitely has a passive board inside for the DB25-Berg-40 transition. For the DECmate I, there's a DC37-DB25 cable from the CPU. For the MINC-11, there is IIRC a 40-pin-to-DB25 cable that goes into the RXV21 (same pinouts as the RX11). I don't remember any Unibus systems using the desktop RX01 enclosure but it would work with the right cabling. For the short term, you can get a 5-10' 40-pin cable and just run it from the RX11 to the RX01 controller board, but you wouldn't be able to close the drive box up. If you are just looking to remove the drive from the box and rack-mount it, they used the standard "Parkerized" grey-finish steel slide rails that were common in 1970s DEC gear. The box is kind of fun, and was standard for word processors and the MINC-11 but I can understand wanting a rackable system. -ethan

Hi Fritz, I'm interested in the RX01 Drive and equipment. Where is the stuff located? Many Greetings Ulrich

They could be wrong. I think the boards are very different and thus easily distinguished : The RX02 boards (which can be set to RX01 mode with a DIP switch on the controller board) : Are interconnected by a 20 way cable ending in Berg connectors The controller board has a pair of 2901s (40 pin chips) and a 2 position DIP switch on it. The RX01 boards : Are interconnected by a 16 way cable with DIL headers The controller board has no 40 pin ICs, no DIP switch. But it has a 36 way DEC-style edge connector for a KM11 board -tony
Re: RX01 wants
I think you mean RX11. I'll see if I have any I can spare. Isn't the BC05L-15 folded up in the case? Or did they put a short one to the back of the box? I can't remember now. There are 3 or so screws on on each side that hold the bottom of the box on. The same screw and holes are used for the slides. I'll look for slides also. Which are you on located?I know someone who was looking for a box last year. Are they the old Calcomp cast aluminum, or the newer DEC 70 class drives? The DEC ones can sometimes be converted to RX02s. I think the older (RX01 only) were the M7726 and M7727. The newer RX02 boards, M7744 and M7745, can be used for either. DISCLAIMER!! I'm taking the board numbers off the top of my head. They could be wrong.

Hi all, I recently picked up a “tabletop” RX01 drive for cheaps. So now I’m in the market for: - RK11 controller - cables - rack ears, rails (how was this done?) - formatted media If anybody here might have any of this and like to work out a deal, feel free to let me know off-list! thanks much, —FritzM.
