It may have been a local language quirk, but we used to call hypo "fixer".

Hi Bill!
Thanks, I never knew that.
It's amazing what you learn when you do research for an e-book on the
history of photography.
And my youngest son did Cibachrome and C-41 when he was in high school,in a carefully blacked out bathroom.
I home processed both colour neg films and Ektachrome slides (then the
C-22 & E4 processes) back in the late 1960's --- but Cibachrome! Now, I
am impressed! That's a tricky one!
I have a number of lovely Cibachrome prints on my walls, but all done by
pro-labs. Sadly, the last run of Ilfochrome (previously called Cibachrome)
papers was made in 2012.It is no longer available, anywhere. Like many
things, killed off by the rise of digital.
So we are, or were, a "wet chemistry" family.
I think the record for "wet development" belongs to a friend of mine in
Vancouver, BC. He has a freezer stockpiled with something like 12,000 feet
of 35mm Double-X Kodak B&W movie stock (5222 - ISO:200), and enough dry
chemicals to make developer for it all. Enough to last him a lifetime!
