+The board project contained in this directory was built in 2020-04 under highly
+adverse political conditions.  It is an LCD carrier board originally built to be
+connected to the expansion interface on the historical iWOW DSK v4.0 Calypso
+motherboard, also compatible with our FC Caramel2 MB built in the later part of
+2020.  The actual LCD module in this design is HaoRan HT020K1QC36S: out of the
+two candidate LCD modules we had evaluated in the FT2232D MCU host bus emulation
+setup back in 2018, this one was a little easier to use mechanically in a quick
+low-effort development board like the one we needed to build in 2020-04.
+
+These HaoRan LCD modules appear to be no longer available (in our 2020 work we
+used the last remaining sample pieces from the batch we got in 2018), but the
+new LCD subsystem board being designed in the lunalcd2 directory (using a
+different LCD module from a new vendor with whom we are engaging in 2021) is
+hoped to be a satisfactory replacement.
