Thanks Dave! J8048A TBP18S42N I looked at the schematics (this is from Red Alert, the Character board) and they label the part "S472". I did a search in the device files and found these 2 entries. Do you think they are a closer match than the 28S42? NAT 54S472 PROM DIP 008/009 V07 C NAT 74S472 PROM DIP 008/009 V07 C This is my first foray outside of EPROMs. Do I need to be MORE careful about static with PROMs? Thanks!

I would try reading it as a TI 28S42 first, use F/P code 13/09. I can't find the 18S42 in my old TI data books and it's not listed on the D I/O wall charts either. It seems to be a very obscure part. Is there a date code stamped on it?
You're probably right about the 2B's revision being the last three digits. Mine is 950-0086-006.
Good luck, Dave

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!
