This computer was my favorite garage sale find of 1995. It even came with it''s own version of DOS, NCR-DOS, and some Peachtree productivity software. But my primary use for this machine was vintage PC gaming. This worked especially well after I installed a used hard card into an available expansion slot. Unfortunately Hurricane Rita tore the roof off the garage where it was stored a decade later, and this machine did not survive being flooded.

My first computer was an NCR PC4. I was in a mom/pop store of some sort. Behind the counter sat the PC4. It was obvious they were getting rid of it. I offered $250. They gave it to me. It had one floppy and an aftermarket 30 MB hard drive. Obsolete even then (1990), but absolutely reliable and great for the college student that I was at the time.

I am currently in process of restoring one of this system, have already installed a new vga monitor inside the case but the motherboard have a DB15 connector for the power supply i need the pinout of this connector or the shematics.

I have a DMV/ color monitor/prtr intfc/ expan mem/ all manuals /cables. I would like to sell.

I have a spare PC4, mono, that likely doesn''t work. But all the components, except the tube, are likely standard, so if anyone wants one they can have that much more fun fixing it! 25$ + shipping from NJ.

As one of three engineers responsible for the design of the PC4 I would like to clarify a few data points. The DMV, designed at our facility in Augsburg, Germany, won the German industrial design award. The DMV ran CPM and MSDOS but was not hardware compatible with the IBM PC. The PC4 was the first fully IBM PC compatible computer from NCR. It was designed and manufactured at the NCR plant in Liberty, South Carolina, USA.

This was the very furst computer that was totally mine as a kid. I simply loved it at the time, and now seeing it again, I almost want to track one down for old times sake.

The all-in-one build was such a pain to work on for even the simplest of things, but other than that, it was one hell of a little computer. This brings me back to days of Hero's Quest in whopping CGA graphics, hopping around bbs's, Norton Commander, and programming black jack in gwbasic.

The big block of manuals were fantastic. I literally always had one with me, going thru page after page of dos commands. A true delight for a geek of a kid.
