The 'drivers' snapshot linked above is missing much for the earlier machines, e.g. 360, 370, 700, 701, 720, 750, 755, since it faithfully replicates the useless Lenovo pages. No criticism intended, that's just what was available when it was archived as Lenovo were about to dump the old support pages.
As a nostalgic nod to the old IBM Personal Computing Support website pages I remember using in the 1990's - specifically TPOPSYS and then TPAD-MATRIX - I've put together a similar tabulated matrix style of download resource for the older machines. It links to the original downloads from the various IBM PCCBBS archives; as a convenience I've unpacked the DOS-only* self-extracting diskette image .EXE files into .IMG and/or .ZIP files, plus created per-model ZIP archives containing all the drivers in one download. I've also linked to User's Guides, HMMs, etc, in the per-model tables, and converted some of the old RETAIN tips (where available) to .PDF so they are readable again.
Here's the link
Thus far I've included:
PS/2 N33, L40, N51, CL57
ThinkPads 340, 345, 350, 355, 360, 370, 500, 510, 600, 700, 701, 720, 750, 755, 760, 765
PS/Note 425 (ThinkPad 350 rebadged)
As you see, there has been some mission creep, e.g. 600 and 760 are well catered for on the drivers link above, but I enjoyed trawling through the PCCBBS files to work out exactly what was there, and in the process gaining a better understanding of sub-model hardware differences (e.g. 600 vs 600E vs 600X) so added them to the list. I might add the 560 and 770 on the same basis. The 310 will not be included
Enjoy!
* well, DOS, OS/2, 32-bit Windows XP or earlier. Not always readily to hand these days
