Gee,
Surprised no one has mentioned Microdol-X as the old time developer for Tri-X.
Have used it since the 1960's, about 8 minutes at 68F.

This reminds me of what happened in 1978 when I was a first year student photography at the 'Royal Academy for Fine Arts' (what's in the name).
As my father did not 'believe' in a career as a photographer, he did not really support my choice and I had to go to school with an 'old' Rolleiflex I had been using as a young amateur for years. But I was full of high expectations and courage. Not for long!
The Royal Academy teachers were not pleased whit me using this kind of camera because all of my fellow students (51 of them) had 35 mm camera's, and they did not like the advantage of my 6x6 camera. As I was used to work on AGFAPAN 400 film and Rodinal, for about 4 years with good results, one can imagine the troubles I had to 'adapt' working on TXP-320/120 and developing it collectively, all together with the 'normal' TRI-X 400/136 in D-76 1+3 as imposed by the Fine Arts teachers. I was not entitled to any 'extravagance' as they constantly remembered me.
Needless to say that after half a year, I still had very poor results, all my megatives ware useless for good printing. And no teacher seemed to have an answer to this, very strange indeed.
Desperately as I was (what else?) I send my negatives and my modus operandi to Kodak Belgium. A few day's later the helpful answer came very clearly. Kodak advised me to develop the TXP-320/120, for the best results, in CONCENTRATED AND REPLENISHED MICRODOL-X! I do not recall the exact times, temperature and replenishment rate, but the results were super from the very first time I followed these instructions! Kodak also mentioned that the TXP-320 should not be processed in diluted developer, concentrated was much better.
But, naive, young and inexperienced as I was I did something very stupid, I showed the letter from Kodak to my teachers... Their reaction was clear too : every time I asked the supposed 'munificent' teacher for something, even simple and small, the answer was : "...why don't you ask Kodak?...".
At the end of that 'interesting' year, I left this Art school for an other one (Sint Lucas)!
From then on, I never touched TXP-320 and Microdol-X again, the remembrance hurted to much...
Salut,
Philippe
