Ono Sokki CF-6400 FFT Analyzer
« on: Yesterday at 05:11:22 am »
Dear folks,

some years ago I could rescue a Ono Sokki CF-6400 4-channel 100 kHz FFT analyzer from the dumpster, even with all manuals included.
As far as I can see the unit still works quite fine and is still very useful for me as an audio-enthusiast, except for the battery (all settings are lost after re-power).

Has anybody got more information on that unit? The schematics could be quite interesting.
Also, the 'operating system' is stored on three EPROMs labeled as D27C040 (I put some tape onto them because the stickers got loose). I think it might be a good idea to do a backup, what do you think?

You find some pictures attached.

Thank you very much!

If you have the manuals, you probably have more info on it than anyone else  :)

If you plan on keeping it, backing up the EPROMs is probably a good idea.
