Looking for: "STP Connector Card" for a VT103

This is a long shot -- anyone have a spare "STP Connector Card" for a VT103? This is a small paddle board that plugs into the main VT100 circuit board (on the J3 slot). Basically it re-routes the external serial port internally in order to allow it to connect to the VT-103's internal PDP-11. It's a completely passive device and I have the schematic, PCB layout, and pinouts so it's not looking like it would be too difficult to just build one, but I figured I'd ask before I went through the effort. (And for those interested, I'm finally doing something fun with the VT-103 I got a few years ago. I've upgraded the backplane to 22 bits, and I've installed a QED 993 board (a 3rd-party 11/93 clone with 4mb memory onboard). Now I just need to work out the SLU connections for the terminal itself (hence the STP connector) and work out some storage... maybe I'll just borrow the SCSI card from my MicroVAX...) Thanks as always, Josh
