The name 84PLC/TA1 seems to imply 84Plus Color revision 1 but if they realized they needed more than 48k of ram for the color calcs and thus went back to the ASIC with more ram. This is pure speculation of course but the naming sure seems to imply that the PLC asic was intended for a new revision of the calc rather than just a minor revision else it likely would have been called the 84PLUSB/TA3. --[[User:TheStorm|TheStorm]] 23:52, 6 May 2014 (UTC)</del></div></td><td class='diff-marker'>+</td><td style="color:black; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div>&#160;</div></td></tr> </table>
