8" floppy connector READY signal

[Christian Grössler]

Hi,

I've built the 8" <--> PC adapter described on Dave
Dunfield's site. It works well with an 8" drive from
an
Olivetti M40 system.

But it doesn't work with a Shugart SA851 drive.

Now, after checking the pin description in the SA851
OEM
manual it seems that the SA851 uses pin #22 instead of
pin #12 for READY.

I haven't tried yet whether the adapter works if I
change it for pin #22...

I'm just asking if it's a well known fact that there
appear to be different layouts of the 50pin 8" floppy
connector. I was under the impression that it is quite
standard.

I'll probably add a switch to the adapzer to select
between pin #12 and pin #22.

regards,
chris
