Serial Number Tags

Overview

The serial numbers on the back of your Kaypro came in multiple different versions over time. I attempt here to show the different styles and potential "skips" in the numbering system.

Small Grey Tag (6 digits) Version 1

Range seen 2561-21460

The first serial number tags that I have seen are the small grey tags with 6 digits.

Small Grey Tag (5 digits)

Range seen 22755-99300

The second serial number tags are similar to the first tags but they are limited to 5 digits. The first one that I know of is 22755. That creates a gap of about 2000 from the previous tags. They appear to end somewhere after 99300.

Small Grey Tag (6 digits) Version 2

Range seen about 100000-158324

Some might argue that this is not a new tag since it appears that these tags were required since they had reached 100,000. I believe the first one would be 100000. (I cannot find a new 6 digit before 100000.) They appear to end somewhere after 158324.

Large Grey Tag

Range seen 200494-215417

The first one that I know of is 200494. I suspect that there may be as many as 40K that are skipped and they may have restarted at 200000. They appear to end somewhere after 215417.

Large White Tag

Range seen 240019-?

The first on that I know of is 240019. Again there may be a skip of as much as 25K maybe restarting at about 240000.
