  Other manufacturers had similar number schemes. IBM

  3 character code on some of their standard TTL (etc)
chips -- I 
 started compiling a list of those as well as they turn up in UK PERQs. 

 The one I would love to get an equivalents list for is Xerox. Xerox 
 D-machines have what are obviously TTL chips with only house numbers 
 on them. I have never seen any equivalents list or dual-marked ICs, 
 though, which makes fixing these machines a little harder. 
Stuff made by Motorola's COMM group was the same way.  WHen I left that
organization in 1986, I took with me a table cross-referencing commonly
used chips with their Motorola Part Numbers.  Very useful, if you deal
with alot with their old (read: mid-80's) radios, consoles, and 
computer-ish things.
