I put up a composite of the TMC0271NL pics that I've taken so far: http://www.seanriddle.com/speakandspell.html There's a 6000 pixel GIMP image at http://www.seanriddle.com/tmc0271nl.xcf
I'll re-shoot the output PLA above RAM and the instruction decoder PLA at top right with a higher magnification objective and post those. Any other areas?
I dumped the '351 and '352 from the other S&S and the contents are identical to the other unit's chips.
