I haven't tried that one, but as far as I know all such things are high speed source document microfilms plus some variation on POTA developer.
If you can find someone to sell you a modest quantity of Agfa Copex or Kodak Imagelink films in 35mm double perf, you could do it a lot cheaper. Most microfilm sellers seem to want to sell film by the case, and I'm not aware of anyone who will currently sell me a single 100 foot roll. It is very cheap by the case, and I wish B&H or someone would sell a single 100 foot roll for double their cost, but they don't.
16mm film and unperforated 35 is easier to find in small quantities, but the perforated stuff that fits our cameras seems to be the least common of the standard formats for microfilming.

It is the same as Gigabit - Agfa Copex Rapid. There is a recommended developer, a so-called 'variation' on the Holden & Weichert formula of 35 years ago. You can make that yourself (I did) and if you make the active ingredient part with glycol/glycerol/brake fluid (yes!) it will keep fine in the fridge. Just make sure you remember how much of what goes with that to get the final dilution. The numbers are weird. As to what to do with it depends if you're a 'grainless' friek. There is none. But it can still be hard to get pictorial results. The phenidone can cause banding of areas of almost constant tone, such as skies. Damned irritating. I bought a can of 35mm, and 16mm for the Minoltas/Kiev miniature cameras and still have a bunch. There are those who swear by C41 developer. Haven't been down that road yet but am considering Dignan's split C41 formula for just this film. Got the makin's just haven't done it yet. Lots of cameras and film - so little time. :-) Good luck you will get lots of experience with occult developer formulae. Murray

I wonder whether, at this late date, it would be possible to persuade Kodak to divulge the formula for Technidol.

Hmm; Richard M? Any thoughts?

Anyone in APUG would possibly know? I'm still finding Technidol in a number of local shops. Stashing it away in large quantities at the mo: used with Adox CMS20, I get stunning results. Adox makes their own developer for their film but Technidol works brilliantly as well.

For the sake of record I measured the pH of Technidol before I poured it into the tank - it was 8.8. This surprised me as plain DEA has a pH higher than TEA. The SO2 may pull it down. The colour of the spent developer even after 7 mins was brown and I expected it to be pinkish if penidone (Dimezone) was the main agent. Didn't know about the HQ altho it could be a substitute for catechol which IIRC was thought to be in Technidol originally. I have no data on that. How active is HQ at pH 8.8? Getting to be like alchemy. Murray
