The top cover has been removed and there are no identifying brands or markings apart from a serial number. The platters are approx. 20cm in diameter.

EDIT: Removing the metal cover reveals some ICs but none appear to have date codes.

EDIT #2: I'm just wondering if the SS9130 and QFVD9146 markings are date codes? Late 1991 perhaps?

It could be anything. An indication as to what sort of interface it uses may help. With 20cm platters, I don't imagine that thing fitting into a PC-compatible any time soon, and before then hard drives were mostly server, mainframe, or mini's domain.

If it's broken, I probably did it.

It's definitely not a PC hard disk, it's from a mainframe or server of some sort. Probably from the 1980's if I had to guess.

In the 1980's we used 14 inch drives in our DEC VAX cluster. Each 14 inch drive had a capacity of about 450MB. This gives an indication on the capacity of this 8 inch drive ...

If you had money, very much of it, you could buy an IBIS 1400. A disk with a weird vertical 14 inch drive with a capacity of 1.4GB. Cray used these drives with their supercomputers.

The date code on the MECL chips shows 1991.  Could be a CDC, IBM or DEC drive.  Ought to be a logo on something to tell for sure.
I did see a hint of a bar code on the edge of the platters.

Yep, it looks like the edge of each platter is encoded with a barcode however they are too narrow for my camera's auto focus to lock onto. No logos at all, I suspect there would have been on the top cover, but that is long gone.

I think the 32R252R's ic's from Silicon Systems date to around 1993. Does it have an IDE (40 pin) connector or a SCSI connector?

If it was IDE, the drive has a maximum capacity of just over 500MBytes and could easily be a lot less. That was as big as IDE could handle back then. If it is SCSI, there were a few brands that went up to about 2GBytes which was massive at the time.

I found out what it was (actually found the other half of the case). It's a Seagate 2GB "Sabre Module Assembly" ML202948 (Assy # 70896783). It looks like it had a SCSI interface but it has been removed. It seems to be part of a bigger system.
