NO, Ed, I won't give it away AND pay shipping.

EARLY 5150, but with trivial modifications, such as
additional holes in
brackets for 4 half-height drives, and probably has a different video
board and disk controller than the IBM ones that I originally bought with
it. At one time, I had a Plantronics 640x400 CGA-sorta-like video, and
I used 8 inch drives with a Vista disk controller, a Maynard, and maybe
one or two others (but only one disk controller at a time; I only did
multiple controllers with 5160 and 5170)
It had a D hole in the back panel, I might have punched an additional
D hole, . . .
I recall it having an unusual black power supply with a white switch (Did
IBM run short of inventory supply?), but I might have replaced that at
some point.
The primary distinguishing features of the very first run of 5150's are:
1) No "B" inside a circle stamped on the back panel
2) Only two case screws on lower right and left of back panel (none on top)
3) Black power supply

Bill Degnan (from whom I learned all this) knows more about this.
