Nice piece, even with single side floppy drive and CGA card.

Odd that somebody f***ed with the insides of the power supply. The motherboard power harness has the wrong connector on it, and somebody's replaced the header on the motherboard too, to match the wrong connector on the power supply.

Please elaborate. I must be missing what you are seeing.


... and somebody's replaced the header on the motherboard too, to match the wrong connector on the power supply.
The different coloured power connectors on the motherboard is normal for very early 5150 motherboards.
As an example, Framer has his early motherboard pictured at [here (http://www.vcfed.org/forum/showthread.php?24223-I-bought-a-model-A-5150-cheap-on-FleaBay)].

I took a pic of my early 5150 for comparison. The serial number is 19157, I am not sure when IBM made changes. The power supply is more bronze in color than black and the 4 nuts on top of the power supply are not recessed.

The power supply does have some discoloration and surface damage, but works.
