It's an IBM 370 mainframe emulator. Here's what I've heard:
There should be a "P" card that should have two Motorola 68000s, both
modified in varying ways and produced under license by IBM on it, plus a
8087. It should attach to the M card that has 512K of ram on it. And
then there's a PC3277-EM card that is just a 3270 terminal emulator that
should attach to the mainframe.
I don't know much more about this, since I'm just getting all this
information second hand. It's allegedly in a book called _Upgrading and
Repairing PCs_, but I don't know the author.
I have that book. It's by Scott Mueller and the one I have is 1988.
Here's what it says (to add to your info):
"...All this hardware is run by a program called the 3270 PC Control
Program. This combination can support up to seven concurrent
activities: one local PC DOS session, four remote mainfram sessions,
and two local electronic notepads. With the assistance of the 3270
PC Control Program, information can be copied between windows,
except that a PC DOS window may not receive information. "
The cards used are:
3270 System Adapter (communication 'tween the 3270 PC & 3274)
Display Adapter (replaces PC's mono/cga card. No graphics unless...)
Extended Graphics Adapter - XGA (required to get graphics)
Programmed Symbols adapter (provides graphics with 3278/3279 stations)
IBM also had an XT 370 that used the PC 370-P, PC 370-M, and
PC 3277-EM cards.
The P card emulates the 370 instruction set. This card has the
Motorola 68K cpu's. It also has the 8087.
The M card is the 512K mentioned above.
And the 3277 card hooks up to the S/370 mainframe.
So I reckon you have the XT 370.
The price of the 370 attachments was $3,000 over the price of the
XT this stuff had to go into. Jeez!

Compared to to a real 370, a console, terminals, DASDs, and what not,
this price is not too bad. Add the fact that the XT 370 likely did
not require a riser floor, motor-generator, air conditioning, and a
square kilofoot of floor space, and it starts to look even better.
I wonder why they were not more popular. Run JCL on your desktop machine!
This may have a strange appeal to me, but how many people really want to
run MVS on a desktop machine? I'd really be interested in knowing what
people used these machines for other than super-3278s.
Anyone know what happened to OpenMVS? (Feels like Unix, works like MVS)
IBM was pushing it in some Unix rags a few years ago.

I used an AT-370 about ten years ago, but not long enough to remember
anything at all about it. We (fed government) had software that ran on
a 360 and I needed to run it in the office. (but never did!)

It exists. I haven't used it much, as I babysit RS/6000 systems, not big
iron. It does have a _few_ places where an old Unix hack like myself
will trip over mainframe conventions that I have little experience with.
But it runs here at the Prudential in Roseland NJ. Hell, it even
supports Samba

Awesome. What a cool find.
Speaking of 3270 stuff, does anyone have a use for any 3279 terminals and
IBM terminal servers, as well as some IBM printers (can't remember the
model number, maybe 3287)? I know a guy who has some that will go to
scrap unless someone wants to pay for the shipping.
