I had no problem expanding disk 177-20.
I did it on a Linux system using wteledisk (which I got from
https://github.com/jmechnich/wteledsk.git) using this script:
for d in
~/downloads/decpro_software/ftp.update.uu.se/pub/professional/PRO* ; do
newname=$(basename $d | tr [A-Z] [a-z])
for f in $d/*.lzh ; do
lha -x $f
for f in *.td0 ; do
~/build/wteledsk/src/wteledsk $f -o`basename $f .td0`.dsk
Here's what the files look like:
$ ls -la build/pos32/decus/pro177/177-20.dsk
-rw------- 1 user group 409600 May 16 2020
-rw-r--r-- 1 user group 152827 Oct 22 1993
$ md5sum build/pos32/decus/pro177/177-20.dsk
Did you possibly download a corrupted copy of 177-20.lzh?
