I'm just wondering if this display actually needs to be connected to both the empeg serial port RX and TX lines. From what I can tell you don't ever read anything back from the VFD. If so then a SPDT switch would do. Also wouldn't a three pin header and a jumper be cheaper than using a switch?

Have you thought about using Veroboard/stripboard actually? The circuit is very simple and wouldn't require much Veroboard and it would save you money on getting a proper PCB.
