I've found the source code to a Vectrex game.  The ROMs start at $0000, 
btw.  This source is filled with spaces where there should be tabs in 
EDTASM-style code, so it will be a while before I can fix this to 
assemble.  After that, I should be able to build the ROM Pak with my IDE 
and emulate it in the Vextrex system.  I'm looking forward to doing this.

It's also apparent that the standard ROM size was/is 4K.  I remember a 4K 
ROM for the CoCo, for "Skiing".  I am not sure if 4K EPROMs are readily 
available or if it's even worth it to build one, but if the Vectrex 
requires a 4K ROM image, then my IDE must support 4K images, so I'm adding 
this now.

It's such a simple thing to add and might even allow a lot of Vectrex 
development/testing.
