This drive uses 3.5" MO disks.
Lets dig in! Oooooh, hey wait? This seems kinda not what I was expecting.
Is that a 3.5" standard drive in a chonky enclosure??

I& #39;m gonna go with yes. Also this is a SCSI drive!
Have a ribbon cable out to the external scsi ports. Molex power from the power supply. And another ribbon cable that turns the scsi id pins into a dipswitch.

Under the ribbon. uPD72050gm.. hmm few references, but one reference to "NEC SEMICONDUCTOR SELECTION GUIDE 1995" In we go.
There it is A MO disk controller! 230mb max size disc for 3.5" drives. Sourced pdf from Elektrotanya. Now at https://archive.org/details/nec_semiconductor_selection_guide_1995">https://archive.org/details/n...
MB86311A is a 16bit DSP
