Oh, these drives are definitely very strange.
Made in Singapore by
IBM Singapore, the connector is like nothing I've ever seen --
it's in four separate little sections, which are 3, 3, 4, and 8
pins wide, but double-sided, and with spaces in between them.
I wonder if this
might be some sort of SAS connector. I guess we'll
find out eventually.
As I said in the thread yesterday, it's an IBM SSA disk connector. It's
IBM's pre-fiberchannel "fiberchannel" - a serial link to connect a
string of disks to a controller. They made MCA and PCI adapters for
RS/6000s, as well as some AS/400 adapters (I think), and it was also
used for storage in the Multiprise 2003 ("small" s/390 system;
processor and DASD in a standard IBM S/390 rack).
Why so many *pins* (conductors)? I think the OP indicated
3 rows of 24 pins (?) Unless there are 20 for each *supply*,
that sounds like an awful lot for a serial device...
