Yes. There's a board that goes under the wooden "top" that has a DB25 on one side, a Berg 40 on the other, and some wires and ferrite beads in between. It should be the identical board that's in the RX01 enclosure for the MINC-11 and/or WT78. The pinouts should be the same even if those use a different part number for the board. > I actually have the DB25-to-DC37 cable that goes between the disk unit and > the DC37 connector on the CPU/display unit. Right. Well documented and easy enough to make, but good you have one. What I need to make (since I've never seen one) is the DC37-dual-DB25 cable to hang all the drives off of the DECmate I. 100% passive and just a few dozen solder joints. > If we move this along we may be asking for system software in the future, > I haven't looked at what may be readily available (i.e. bitsavers) as yet. I think mine came with WPS-8, but it should run OS-278. You just need to find a way to write RX02 floppies. I need to come up with a semi-portable PDP-11 rig with RX02s and 256K of RAM so I can cut floppies with vtserver (and probably some RL01 and RL02s while I'm at it) -ethan
