+# ZDE 1.6 (Z-System Display Editor) reconstituted source - MECPARTS 
+11/19/2020
+
+Using the source code of [VDE 2.67]
+(http://www.classiccmp.org/cpmarchives/cpm/Software/WalnutCD/enterprs/cpm/utils/s/vde267sc.lbr)
+as a guide, I've reconstituted the source code for [ZDE 1.6](http://www.classiccmp.org/cpmarchives/cpm/Software/WalnutCD/cpm/editor/zde16.lbr).
+
+The source has been assembled with:
+
+* Al Hawley's ZMAC: assemble as is.
+* MicroSoft's M80: rename to ZDE16.MAC, un-comment the first two lines
+  and assemble. Use RELHEX to create ZDE16.HEX.
+* ZASM (Cromemco's ASMB): Rename to ZDE16.Z80 and assemble. Use RELHEX
+to create ZDE16.HEX.
+
+Use MLOAD to create ZDE16.COM.
+
+There are still a couple of routines new to ZDE that I haven't figured
+out (yet). But most of them have been sussed out.
+
+## ZDE 1.7 - MECPARTS 11/24/2020
+
+I've fixed the "doesn't preserve timestamps for files larger than a
+single extent under ZSDOS" bug that was present in v1.6. The existing
+ZDENST16.COM program will work with the 1.7 to set the program up for
+your terminal and printer.
+
+## ZDE 1.8 - Lars Nelson 12/3/2022
+
+Added routine to save create time stamp under CP/M Plus since 
+CP/M Plus, unlike ZSDOS, has no native ability to set time stamps.
