I don't recall what hard drive it was that we used when back at
Intel. We used a number of Series IIs and MDS-800s. We had some
type of network so that hard drive could be shared between
machines.
The drive had one removable platter and one fix of 5 Megs each.
We salvaged the drive from scrap that was going to be junked.
It had had water in it while running and it had destroyed the fixed
platter. We cleaned up the heads and took a platter from a spare
cartridge to bring it back to life.
We used it for the programs that we regularly used. Editor, assemblers
and PLM compilers. Our favorite editor was called X1.11.
The Series IIs were upgraded with better IOC software and even a
8086 boards. We had floppies using the M2FM ( double boards
mentioned previously )
I was responsible for test programs for the analog board, as well as
the UPP.

Subject: Re: Intel MDS 225 system being auctioned by Chicago Transit Authority
The Chicago Transit Authority is auctioning off a
whole load of
miscellaneous stuff (including a couple of rail cars!). One of the items
being auctioned is what appears to be an Intel MDS 225 "Blue Box" (4 MHz
8085A system) complete with an MDS 720 disk expansion unit and some sort of
Control Data hard disk.
The specific lot is here:

Looks to have lots of multibus cards in the slots. Two for the double
density floppy controller. I would guess two for the Hawk drive
(although I've never had any experience with that particular
combination). The internal floppy drive is converted to double density.
In the expansion chassis I would guess there is some sort of in-circuit
emulator. I don't know how to tell what one it might be, or even two.
It'll probably cost a couple hundred to ship it, maybe more. Those
things are heavy!
