Most often the screw pattern/spacing can be an issue. It's very unlikely that a table would list compatibility with an older router like that. If you measure between your plate screws and then measure the spacing on a table in the store, you should be able to tell if it will mount in existing holes. Or even easier, take your base-plate off and bring it to the store to compare.

I used a router similar to that for years to cut plexi for signs.

I just noticed a post about a Bosch table with a Ryobi router. He mentions another pattern of holes besides the plate ones which worked for him. Perhaps your router has more than one set too. They're usually in a triangle or rectangle pattern.

Seeing Jack's 'Rebel Router' brings back memories of cutting sign faces. We got many miles out of that inexpensive router. Sometimes whole plaza lengths of plexiglass cut to size with a 1/4" to 3/8" straight carbide bit, using a 20 foot piece of EX-1 aluminum extrusion for a guide.
