I looked thru my collections of formulas and found the following.

Developer for T-Max Films

This formula produces results similar to those of the T-Max developer. <BR>

Distilled water (50C) 750 ml
Sodium sulfite (anhy) 100 g
Hydroquinone 3.5 g
Dimezone S 2.2 g
Sodium metaborate 14.0 g
Boric acid 6.0 g
Ethylene glycol 100 ml
Distilled water to make 1.0 l

Use the same dilutions and development times as for T-Max developer.

Another TMax developer

Distilled water (50C) 750 ml
Sodium sulfite (anhy) 5.0 g
Dimezone 1.4 g
Hydroquinone 9.0 g
Diethanolamine SO2 adduct 20 mole % 130.0 g
DTPA Na5 5.0 ml
Distilled water to make 1.0 l

The second formula looks like it might be closer to the Kodak product since it contains two special chemicals found in HC-110.
