The A807 comes in a 4-track variant, though I think it's always 1/2". There is also the C278 which is an 8-track variant but again, is 1/2". There is no 8-track 1/4" version. I suspect Telefunkin posted in the wrong thread by accident or something.
So yes, as far as I'm aware only Fostex and Tascam produced 1/4" 8-track machines.
