* Terco T4426 CNC Programming Station multi cart
*
- * The code here is heavily inspired by coco_pak and coco_232
+ * The T4426 is based on a Color Computer II PCB revision 26-3134A with a modified
+ * Extended Basic fitted through an adapter and a soldered wire as one address line
+ * was missing. Modifications involved obfuscation changing names of some common
+ * commands such as LIST renamed to LARS (which happens to be the name of the CEO).
