There is a reference to one (TI.C24.970) in the SC.24 leaflet but I've never come across an example.

The poor-quality schematics are no help to the restorer and in the end it was necessary to cross-check the boards against each other and the schematic to be sure that all disparities had been caught. If anyone wants a list I’ll be happy to provide one. All the boards in my example have part numbers suffixed /3 for what that's worth.

Restoring the SPA.50 was entertaining as well…
