I don't quite know why it never caught on.

Does anyone know what eikonogen is? Metol perhaps? Interesting formulas.

Was that the first Jobo???? ;>)

Eikonogen was 1-amino-2-naphthol-6-sulfonic acid.

I would maintain that it did -- you see the modern equivalent every time you pass the hour processing counter at the local drug/grocery/big box store. Also reminds me of the beloved (and beloved to any other ex-US Navy Photogs who might be reading this) Kodak EH38D Versamat processor:

ah... I can almost smell the chemicals and the rubber and fiber board rollers and hear the chains cranking the film through there now. The link above is from a lab selling theirs for $850.00. If I was a 20-something working in IT with nothing to spend my money on... I'd be very tempted to get it, of course, then I'd have to get the rollfilm contact printing machine to use with it.

I once saw a very high speed motion picture film processor that looked a bit like a half dozen of those linked together with a belt transport.

It never left the research labs, but was a pretty neat design and did a terrific high speed processing job.

Gerald, you lost me on this one. Is there a common name for this?

Sorry, none that I am aware of. It is an obsolete developing agent introduced by Agfa in 1897. It was used as the sodium salt.

There is: Eikonogen. Sorry...

My father used to help build processing machines (did the wiring I presume, since he was into electronics). We used to go on road trips to deliver the things (it used to be delivered on a tandam trailer pulled by the bosses Rambler... our Datsun would never have towed it!) Every now and then I see one come up in our eBay and wonder if it's one that Dad worked on and we delivered. Amazing that they haven't all been scapped long ago since this would have been in the mid '70's. As this was a second job for Dad, I used to go some weekends and got to play on the plastic bending machine... a highlight for sure!

I asked for that!

And Eikonogen is still used in biochemistry to determine phosphate ions by colorimetric assay with molybden blue... gee, looks like I got about a kilo bottle of it somewhere in my lab!
