-The '''155-0087-00''' is a Tek-made custom Legend Generator IC
+The '''Tektronix 155-0087-00''' (M166) is a Tek-made custom legend generator chip in a 20-pin DIP, designed by [[Roger McCoy]] and [[Mike Metcalf]].
-for the readout system of the [[7D15]] counter plug-in.
-It comes in a 20-pin plastic DIP.
+It contains a 12×10×4 read-only memory coupled to a 4-bit D/A converter with internal current sources that can
+directly interface with the row and column current inputs of the [[7000 series readout system]].
+The 155-0086/0087/0088/0104/0105/0135-00 (M165, M166, M167, M169, M170, M171) share the same silicon and differ only in the metallization layers.
+==Used in==
+* Readout interface of the [[7D15|7D15 counter plug-in]]
