How do I read a TI 18S42 with a Data I/O 29b/2b?

How do I read a TI 18S42 with a Data I/O 29b/2b? I did a search through
the device files and found no match. A search on Google found this article:

http://groups.google.com/groups?selm=leD3a.129288%24vm2.77578%40rwcrnsc54

So can I read this as a AMD 27S29, a device that the 2b supports?

A couple unrelated questions:
1) What is the A/C (last) column in the device lists?
2) How do I tell the version number of my 2B? On everything else it's
obvious. Is it the last 3 digits of the part number? So 950-0086-011
would mean I have a version 11?

Thanks!
