 According to my list, the 8085 has the IBM number 4178615. 
I was goingto ask...
There is a well-known equivalents list between HP house numbers and
stnadard numbers in various issues of Bench Briefs (which are now on the
web I think). IS there a similar list for IBM house numbers...
[With reference to the HP list, be careful. Some chips were dropped from
later editions of thr list, it appears only those chips in instruemtns
that were still supported by HP are included. You may need to check
several lists to find the IC. Don't ask how I discovered this!]
