Odd Q-Bus questions 18/22bit

You should be able to do that... but the VT103 had some special paddle board which plugged into the connector on the VT100 basic video board and which provided a connector (2x5) which connects to something like an MXV11-B, and a second connector which also attaches to the MXV11-B (or DLV11-J) and routes the signals through to the external connector (if I remember correctly - otherwise it provides a separate external conenction). I'll have to open up my VT103 at work one of these days to get the info for you (like part numbers).
