The two I own are: 2630-2TU and 2630-7TU

Just curious in my never ending quest to archive info

The only folks that know it all are the IBM/Lenovo ones.
Whatever us mere mortals know is mostly contained in the TWBOOK
The 2630 is the TYPE.
The XXX is the MODEL.
XXJ last model letter J: usually destined for Japanese market
XXU last model letter U: Universal model for mostly North America
XXG last model letter G: General model for mostly Europe

The XX and other last letters denote the amount of RAM, HD size, screen size/resolution etc., the key to which is held by (see first line).

I was thinking the same for the J(apan) U(S) E(urope) at the end... but then i found all these A(sia??), 1 thru 9(???), W(???), M(???), F(rance??), C(???)

And then the 1st 2 digits... could be... 2 diff processors tween the C & CS models (is the 701CS still a 2630?), 3 diff hard drives(360, 540 or 720MB), then all the possible non-standard ram combos...

Would be really cool to find the actual meanings of these, thus the post. I know like for old cars... the option codes are now WELL documented... you can find the options sticker in a car and for most brands restore them to there EXACT factory specs.

Plus I see a lot of questions on eBay asking for model numbers, was thinking these people were asking cause they knew how to decode em

People just want to be able to look up the original specs, in my opinion.

Deciphering the 7-character mumbo-jumbo is way more difficult than decoding a VIN (or a chassis number on an older/imported vehicles) ....and I've been down both of these roads more than once...

There's another part of the code, which is the actual serial #...

Enough to drive you nuts. I've given up on all of that a long time ago.

Here's to patience... ...may it get you somewhere, ozzymud...
