Control Data hard disk.
The specific lot is here:

Despite being local *and* placing a low bid on the lot, I completely
dropped the ball (mouse?) and forgot about the closing.
Did anyone here end up with this fine blue machine?

What exactly did you get? What density is the boot drive? I may be
able to help you out with a boot diskette.

There's a single-density boot image on bitsavers, IIRC. Any MDS will
boot single-density. But the OP has been told this on Erik's VCF when he
asked.

I've seen several that were upgraded that way.

Thanks Dave for mentioning that. That is what I thought
as well. I was just afraid to say so.
One could still connect the internal drive to the IOC board
and run it as a single density.

Yeah, I remember both the DD and SD versions of the board set--and I
remember how hot the channel board ran. One of the first questions I
asked on the VCF posting was whether or not the OP had the DD board
set--kind of hard to miss. He reported that he did not, so he's running
off the 8271 built-in controller.
If he was using the DD board set, that would create an interesting
issue, as it uses MMFM, not MFM for encoding. Not something easily done
on a PC.
Fortunately, it's clear that plain old SSSD disks will work just
fine--and he can probably use a PC to write the images to disk.

This is the auction listing for it here:
http://www.ebay.com/itm/261336294714?ssPageName=STRK:MEWNX:IT&_trksid=p…
I'm afraid I don't know that much about these units. There used to be one at a
'museum' in a computer store we used to frequent, and I determined I had to have
one one day. This one came up and I jumped on it.

You'll need a keyboard. They used parallel out type keyboards.
Not that common now days but it can be emulated with a
printer parallel port.
