Bingo. I have a Corvus enclosure and DE-9 transceivers from the first
Mac installation at my Mother's typesetting shop (late 1980s). The
drive is a FH 5.25" mech in a shoebox with a PSU and Corvus Omninet
board. ISTR it uses a Walkman-style connector from node to node.

ISTR it died before she gave it to me. Not sure if the HD mech
went Tango-Uniform or the PSU or the Omninet board.

She replaced it with 18-20MB drives in/next to each Mac. She continued
to use the Mac 512Ks she purchased at the same time as the Corvus drive
until she closed up shop, c. 1997 (but those particular Macs had been
upgraded (officially) to 512Ke (new drive and ROMs) and had a Dove
Snap installed, giving them 1MB total and SCSI).
