Information about a Lexmark M15

[TheRavenDog]

Recently, I had the good fortune of acquiring a Lexmark M15.





But I can't seem to find any information about it's "Part No." and "ID No."

It is a Part No: 1378300 with ID No: 327. I think the 1378300 was the first of the Model M15s. I think the ID No. is the unit's unique serial number.

The only google search for the part number is this  page: http://www.flickr.com/photos/njr/406263107/in/photostream/.

If the ID No. is sequential, then I may have found the 327th M15 every made! It certainly is one of the earliest production dates I've seen for a M15 (after a quick look at clickykeyboards.com).

Does anyone know anything more about the Part and ID numbers?

Thanks,

Chris Petersen.

The part number is the OPN - so when you ordered an M15 from Options, you specified a PN 13H6689 not an "M15." Plt No L1 confirms it as Lexmark, Kentucky plant (this is consistent across all IBM keyboards) - which is the only plant to manufacture the M15. The OPN distinction there is important - you've got an extremely rare Lexmark branded M15.

The M15 serial numbers started at 0000000 - so it would technically be the 328th. However, the highest observed serial number for '94 (reset to 0 for '95 for some reason) is 0001895 - with the lowest seen in the wild for a '94 being 19. And it's unknown if the Lemark branded ones are in sequence with or separate from the Options sequence.
Given the spread and other data, I suspect the entire production run for 1994 may be less than 3000 units and they're shared for both PNs.
