I have an IBM XT 5160 that came with two of these Mitsubishi M4851 floppy drives.
They have a 1985 date on the serial number stickers.
They have an unusual "door" that I had not seen before.
Most ICs on my motherboard have 1984 date codes. All pre-1985.

I have this 5160 motherboard that just blew a tantalum capacitor, and noticed a few things about it while working on it.
64-256KB
Board p/n 6320155
Chips are mostly dated early/mid 1984
The tantalum capacitors are common 2-lead, not the more usual 3-lead I've seen before on IBM PC...
Any info available on this SIO-3 Combo Controller board?
Uses a UMC UM8388 floppy controller chip and HM83C452L chipset.
Marked SIO-3 on the front and IDE IO 345 on a paper sticker on the solder side.
The topic of these DS8837 bus rReceiver chips comes up from time to time.
I bought 50 of them, "used, socket pulls" for $6 plus postage from Electronic Surplus in Mentor, Ohio.

I have an original box for an IBM PC 5150 CPU.
Just the box, the internal packing materials are long gone.
It's been in the hot humid attic here for 29 years.

"Easter" is written on one of the inside top flaps...
