While not as early a run as Eric's this one has a serial number of 119719. If Eric is right and IBM started their serial numbers with 100,000 it still was made in the first 20,000. I am not sure how many 5150's IBM made, but I suspect several hundres thousand if not a million or more.

The BIOS is dated 1981 and is numbered 5700051. The case has what appears to be a 25 DB pin knockout above the serial number. The power supply in black in color or slightly bronze with the nuts on the outside and not recessed. The speaker holder is metal rather than brown plastic and the connector is a right angle rather than a straight up connector.

It came with 4 cards installed a Monochrome Card with a Berg Connector. A Qubie modem, an Apparat, Inc. memory expansion card and a floppy controller. I believe the Monorchrome Card and Floppy Diskette Controller are early version based on the link Modem 7 send me about another machine.

I have attached some pictures.

Yes that's from the 1st batch. Does it have original SS floppies and case cover?

It has the case cover, but the floppies had been replaced. I do have a couple of SS floppies to install.

Jimmy, if that is true that is pretty cool. That also means two board members (http://www.vintage-computer.com/vcforum/showthread.php?36547-Ibm-pc-5150a-Possibly-a-pre-release-build&p=290783#post290783) have 5150s from the first 3500 produced. I have one with serial number 103175 and PCFreek (http://www.vintage-computer.com/vcforum/member.php?28937-PCFreek) has one with serial number 101911.

Mine is complete (i.e. it comes with everything original form the factory), alas no box. I believe PCFreek's is a case and parts (no original MB). He got it from a seller who was parting out the computer.

Excellent find for you! Enjoy it! I am glad to see these early one's ending up in the hands of enthusiasts who will take care of them!

It was on eBay last week. I am the only one who bid on it. I was really surprised. I was sure it was one of the first run, but had no idea the serial number was that low. Any luck with the IBM 7531?
Other than I have to install the SS floppies and clean it up, it seems to be okay.

I was eying that one, almost bid, but have reached the regrettable point of "yeah, but where am I going to put it" since I just added a Jr and a Coco 3 to my collection.

Glad to see it went to someone who can appreciate it.

I understand, I am the same way. I have got to let some thins go.

I need to trade some larger items for smaller ones.

Sometimes you get lucky like that... Usually its other people who get lucky and not me.... But hey I am not complaining ;)

No luck on the 7531. Al Kossow gave me a line on a 7532 up I already have two of those beasties! I was thinking of picking up the third one but the seller dropped off email. So I am still looking for a 7531...

Nice find Jimmy. That aught to be worth a pretty penny or two.
