I just printed some board handles for a 32k OMNIBUS board (thanks Vince Slyngstad, et al.) I now notice that all the OMNIBUS boards have an extra 0.1in spacer between the board and the handle. UNIBUS and QBus boards and logic flip chips don't have the spacer.
Anyone else notice this and understand why? The only thing I can see is that it might adjust for the over the top connectors used on a lot of OMNIBUS boards. -chuck
