It's not really similar at all, (well not to any form of Rodinal)

The Sulphite content is more than ten times higher and the pH is close to 7 whereas old Classic/Rodinal must be nearer 9-10 (that's a very quick guess, but it should be roughly 11.8 before dilution).

It does show quite nicely how Kodak switched techniques though to high sulphite levels for fine grain
