Parodinal

Source: http://silent1.home.netcom.com/Photography/Dilutions%20and%20Times.html

Water - 250mL
Acetaminophen - 15g (30 x 500mg tablets)
Sodium Sulfite - 50g
Sodium Hydroxide - 20g

Mix in order indicated, let stand in sealed container 72 hours before using. Keep crystals from bottom of container with liquid when decanting, stir before drawing off concentrate for dilution. Use dilutions and times as for Agfa Rodinal. Use within 30 minutes of dilution.
This isn't an ascorbate developer but can be combined to make a good one.

Borax - 19g
Ascorbic Acid - 6g
Phenidone - 0.15g

Use the same start times as D-76.  Re-use the developer as 1L will process at least 12 rolls of film.

PC-Glycol

Source: http://unblinkingeye.com/Articles/Preserv/preserv.html

Part A:
Propylene Glycol - 70mL
Ascorbic Acid - 10g
Phenidone - 0.25g
Propylene Glycol to make 100mL

Propylene glycol should be heated to help dissolve the ascorbic acid and phenidone.  Dissolve each ingredient before adding the next.

Part B (Carbonate):
Water - 750mL
Sodium Carbonate (anh) - 5g
Water to 1L

Part B (Borax + Lye)
Water - 750mL
Borax - 6.1g
Lye - 1.7g
Water to 1L

Part B (Bicarbonate + Lye)
Water - 750mL
Sodium Bicarbonate - 2.8g
Sodium Hydroxide - 1.55g
Water to 1L

Use 20mL/L part A diluted with part B.  I prefer the borax+lye solution as it plays nice with my hard water and is compatible with acid stop.  Start times are the same as D-76 1+0, generally 7:30 for most films.  If using as a print developer use 40mL/L part A and add 1g/L Potassium Bromide.  If using for stand development add 0.04g/L potassium bromide to ensure even development.

RCB

Source: Original recipe by Michael Madio

Parodinal - 20mL
Ascorbic Acid - 6g
Borax Saturate - 400mL
Water to make 1L

Tested with semi-stand development (5 min pre-wet, 60 sec initial inversions, 10 sec inversions at 60 min, 120 min total time).  Expose film at +2 for best results.  Gives the tonality of rodinal with much finer grain and highlight compensation.

PCM

Source: Various, insipired mainly by posts from Patrick Gainer

Part A (a.k.a. PC-Glycol):
  Ascorbic Acid - 10g
  Phenidone - 0.25g
  Propylene Glycol - 100mL (warm/heat to fully dissolve ingredients)

Part B:
  Potassium Bromide - 0.2g (make a 10% solution as it's easier to measure)
  Sodium Metaborate 1% - 1L (6.92g borax + 1.45g sodium hydroxide in 1L water)

Use 8mL part A (0.8g Ascorbic Acid + 0.02g Phenidone) for every 1L part B.  Start time is 8 mins @ 20C.  Full stand development (60 sec initial inversions only) for 90 mins gives a +2 push with highlight and contrast control.  For C-41 film, full stand development (60 sec initial inversions only) for 60 mins gives a +1 push.

MF-1 Fixer (Michael's Fixer #1)

Source: Original recipe by Michael Madio largely inspired by TF-3

Ammonium Thiosulfate - 120g (200mL 60% solution)*
Sodium Sulfite - 15g
Borax - 5g
Water to make 1L

*Ammonium Thiosulfate 60% solution is also available as 12-0-0-26S liquid fertilizer.

Use undiluted and 1L will fix 20 8x10 prints or rolls of film (very conservative).  This is a low-odor rapid fix that is simple to make.

MF-2 Fixer (Michael's Fixer #2)

Source: Original recipe by Michael Madio, an evolution of MF-1

Ammonium Thiosulfate - 120g (200mL 60% solution)*
Sodium Sulfite - 15g
Borax - 5g
Boric Acid - 5g
Water to make 1L

*Ammonium Thiosulfate 60% solution is also available as 12-0-0-26S liquid fertilizer.

Use undiluted and 1L will fix 20 8x10 prints or rolls of film (very conservative).

From a functional perspective this is no different than MF-1.  The addition of boric acid is to reduce the ammonia odor.
