Ah, that rings a bell, although mine (NEC part number 806-220510-0 Rev. A)
is marked "NEC proprietary." :-) I also have "D2200 Series 8-inch
Winchester Disk Drive Theory of Operation" (NEC 819-000080-3001, March
1982) and "D22x7 Series 8-inch Winchester Disk Drive Maintenance Guide"
(NEC 819-000080-8001, December 1983).

Twenty years ago, I was working on a commercial development project that
employed the NEC 2257 drive in an emulation of the HP 79xx-series MAC disk
drives. The project never panned out, but I still have the drive and
associated power supply here.

(The project was always chasing disk drive technology -- the 8-inch NEC was
much smaller and lighter than the 14-inch Kennedy 53160 we started with,
but not as small as the 5-1/4-inch Maxtor EXT-4000 we ended up with.)
