I’m trying to identify Canon EOS film cameras that use the older T3 connector for a wired remote or vertical shutter release, rather than the later N3 connector. Is there a known list of EOS bodies that use the T3 socket, including models that require an optional grip for vertical release support?

There were several early EOS cameras that used the T3 connector for both wired remotes and to connect a vertical shutter release. Many of those early models are listed at this link that was current as of 1993. "compatible with T50, T70, T80 & T90 cameras as well as the EOS-1, EOS 5/A2E/A2, and the EOS 620/30/50/RT series when those cameras are fitted with optional grip GR-20"
The vertical release was only available directly from Canon Professional Services and was not distributed via the Canon dealer network. By the year 2000 the T3 vertical release was a rare, hard to find item.
You can still find adapters that allow using standard cable releases with 2.5mm stereo mini plugs (what Canon calls the E3) with cameras with a T3 socket.

Yes. The older Canon T3 connector was used on several early EOS film bodies before Canon moved to the N3 connector (the EOS 3 is commonly noted as the first to use N3).
Based on the information provided, T3-compatible EOS models include:
- EOS-1
- EOS 5 / A2E / A2
- EOS 620 / 650 / 630 / RT series
- Some cameras required the optional GR-20 grip for the vertical shutter release connection
The cited compatibility list also included Canon T-series cameras (T50, T70, T80, T90), though those are not EOS bodies.
A key detail is that the T3 vertical release itself was a niche accessory and was reportedly available mainly through Canon Professional Services, so it became rare fairly early on.
If your goal is simply to trigger the shutter, adapters exist that let you use a standard 2.5mm stereo remote (Canon E3-style) with cameras that have a T3 socket.
